This chapter covers various IBM i system management topics, including IBM Navigator for i, Advanced Job Scheduler, improved mobile access, and other work management topics.
This chapter describes the following topics:
For more information about the IBM i 7.2 system management enhancements, see the IBM i Technology Updates developerWorks wiki, found at:
2.1 IBM Navigator for i
The IBM Navigator for i is a web console interface. Using it, you can perform key tasks to administer your IBM i system. Most tasks that are available in the IBM System i® Navigator Windows client application are also supported within IBM Navigator for i. There are also additional functions that are available in IBM Navigator for i that are not found in the System i Navigator Windows client.
Unlike the Windows client application, nothing needs to be installed on your workstation for you to use IBM Navigator for i. The web application is part of the base IBM i operating system, and can easily be accessed by pointing your web browser to the following URL:
http://system:2001
The following IBM Navigator for i topics are covered in this section:
For more information about IBM Navigator for i, see the following websites:

2.1.2 Usability and performance improvements
By using Dojo technology, there are now significant improvements in IBM i 7.2 within the workspace for the following areas:
Navigation area
Similar to the IBM i Navigator client application, the task categories can now be opened to display any resource containers in the navigation area. It is now much easier and quicker to access tasks.
Common list view
Common list views now use new Dojo tables that make it easier and quicker to filter lists, scroll through large lists, and select items in the list to perform related actions.
Handling of tabs
After multiple tasks are selected, resulting in multiple tabs in the console workspace, data is no longer refreshed each time that you click back to a previous tab.
2.1.3 Searching for a task by keywords and CL commands
On the Welcome page within IBM Navigator for i, it is now possible to simply enter a keyword as a search argument and the related CL commands are automatically shown. Simply clicking the corresponding CL command redirects you to the corresponding task within the navigation pane, as shown in Figure 2-1. This is a quick way to access a particular task without having to navigate to it by using the navigation hierarchy.
 
Note: You can also type in a phrase that describes what you want to find (for example, create a user) or a system value (for example, qpwdlvl).
Figure 2-1 Search a task by keyword
2.1.4 Bookmarking your favorite tasks
There is now a new Favorites node in the navigation area. These favorites are saved and shown by user profile and system. It is possible to save a particular list view as a favorite. Favorites can also be organized by category.
Most likely, there are a few specific areas of the IBM i systems management that you use often during your daily job. For example, if you are interested in the jobs for a specific user, click Users and Groups  Users, find the user profile in which you are interested, right-click that user profile, and select User Objects  Jobs. From the Actions menu, select Save as Favorite, and specify a name for the task (TOMV_jobs in this example) and the category (SYSMGMT in this example) that you want.
The task, TOMV_jobs, is now displayed in the SYSMGMT category under Favorites in the navigation area, as shown in Figure 2-2.
Figure 2-2 Save an action as a favorite
2.1.5 File systems
The following new file systems actions were added to IBM Navigator for i for IBM i 7.2, allowing users to do the following tasks:
Upload files to an IBM i directory.
Download files from an IBM i directory.
Edit certain types of files.
Go to an Integrated File System folder.
Uploading files to an IBM i directory
In IBM i 7.2, by using the File System task in IBM Navigator for i, users can now upload files from their PC or a mapped drive to an IBM i directory, as shown in Figure 2-3.
Figure 2-3 Upload files to an IBM i directory
Downloading files from an IBM i directory
A similar interface is available for downloading files from an IBM i directory to the user’s wanted location, as shown in Figure 2-4.
Figure 2-4 Download files from an IBM i directory
Editing certain types of files
Another feature that is now available with IBM i 7.2 is the ability to edit files by using the IBM Navigator for i interface. To do this task, you must first specify the file types that you want to be able to edit. Complete the following steps, as shown in Figure 2-5:
1. From the main IFS list, select Properties from the Actions drop-down menu.
2. On the Integrated File System Properties window, enter the file extensions that you want to be able to edit and click OK.
Figure 2-5 Specify the file types to be able to edit
The user now sees the Edit action appear for these types of files when right-clicking them within the IBM Navigator for i. Selecting the Edit action opens the Edit window, as shown in Figure 2-6. The user now has full edit functionality for that specific file.
Figure 2-6 Edit a file in the IBM i Integrated File System
Goto Integrated File System Folder function
The Goto Integrated File System Folder function was added in IBM i 7.2. You can use it to go quickly to a specific folder within the Integrated File System. All the previous selections are saved by user profile and system within the IBM Navigator for i environment.
Within IBM Navigator for i in IBM i 7.2, it is now possible to enter directly a specific Integrated File System path, as shown in Figure 2-7. This task saves you time because you do not have to drill down the entire Integrated File System path.
Figure 2-7 Go to a specific IBM i directory in the Integrated File System
2.1.6 Target Systems and Groups
Target Systems and Groups is a new navigation node in the IBM Navigator for i, as shown in Figure 2-8.
A new interface is available to specify the target system to manage and to be able to group similar target systems into groups. A specific target system can be part of several systems groups. You can select to manage another IBM i 7.2 system. IBM i 7.1 and IBM i 6.1 systems are also supported.
In the example that is shown in Figure 2-8, one System group is defined (ITSO residency IBM i 7.2 Technical Overview) with the following two target systems:
One running IBM i 7.2
One running IBM i 7.2 with TR1 installed
Figure 2-8 Target Systems and Groups option
2.1.7 PTF management
Within IBM Navigator for i in IBM i 7.2, it is now possible to perform program temporary fix (PTF) management-related functions. Program Temporary Fixes is a new section under the Configuration and Service task navigation area, as shown in Figure 2-9, and you can perform the following tasks:
Display PTFs: Display PTFs for a specified product.
Display PTF Groups: Display all group PTFs on an IBM i system.

Collection Services system monitor support
With IBM i 7.2, IBM i Collection Services is used to collect system monitor data 24 x 7.
System monitor metrics have the following characteristics:
They do not exist in raw collected performance data.
They are a function of selection, grouping, and other calculations, including rates, percentages, and maximums.
IBM Navigator for i system monitor metrics are now produced by Collection Services and exported to database files. They are no longer stored in private *MGTCOL files like they are in Management Central. For more information, see “Differences with Management Central monitors” on page 67.
These files contain metrics that are defined for system monitoring along with other supporting data and include metrics that are supported by Management Central and more. Also, existing Collection Services files can be used for drill-down and detailed data. Data is easily accessible by the monitoring function and visualization tools (PDI), and data is also easily accessible to any other consumers and can be used for more in-depth analysis as necessary.
When system monitor data collection is enabled, monitor metrics are exported by Collection Services into a second Collection Services file-based collection for the active collection. A second batch job (CRTPFRDTA2) is submitted to produce the system monitor collection. System monitor file collections contain only database files that are related to the categories that are selected for system monitoring.
The database file interval that is used by CRTPFRDTA2 is always 15 seconds. Data is present based on the interval at which each category was collected. Also, system monitor file collections have a separate retention (expiration) period than standard Collection Services file collections.
Existing PDI perspectives can be used with this collection if all required data is present.
Here are the Collection Services system monitor files:
QAPMSMCMN (*CMNBASE)
 – Lines and LANs metrics
 – Still can exclude unwanted lines
 – Includes line count, average and maximum utilization, average kilobits received and sent, and the line with highest utilization
QAPMSMDSK (*DISK)
 – Disk metrics, including all units, system ASP, user ASPs, and IASPs
 – Includes number of entries in data, average and maximum busy and device name, average and maximum capacity that is used, and device name
 – Total capacity available and used
 – For both reads and writes: Ops, average response and service time, maximum response time, and maximum device name
QAPMSMJMI (*JOBMI)
 – Interactive and batch job metrics depend on the MI
 – Includes job count, total and maximum unscaled CPU consumed and percentage and job, and interactive transaction rate
QAPMSMJOS (*JOBOS)
 – Job metrics depend on the OS
 – Includes job count, batch LIO rate, and average and maximum interactive response time and job
 – Spool file creation rate, count, and name of job created the most
QAPMSMPOL (*POOL)
 – Pool metrics
 – Includes machine pool fault rate, count of user pools, and average and maximum user pool fault rate and pool
QAPMSMSYS (*SYSLVL)
 – System metrics
 – Scaled and unscaled: Configured, uncapped, and virtual CPU percentage
 – Speed percent, and virtual and physical shared pool percentage
 – Temporary storage that is used and percentage, and unscaled SQL CPU percentage
The same system monitor metric data can also be generated without starting a system monitor within IBM Navigator for i.
System monitor files (QAPMSM*) can be generated for your Collection Services collection by specifying the following options:
CRTPFRSUM(*ALL) on the Configure Performance Collection (CFGPFRCOL) CL command.
CRTPFRSUM(*ALL or *SYSMON) on the Create Performance Data (CRTPFRDTA) CL command when running manually.
System monitor data collection can also be enabled through the Configure Performance Collection (CFGPFRCOL) CL command by specifying ENBSYSMON(*YES). This does not start
any monitors.
Specify the categories that you want collected more frequently by using the SYSMONCGY parameter of Configure Performance Collection (CFGPFRCOL) CL command. This command starts the CRTPFRDTA2 job that creates the second database file collection starting with
an R.
 
Note: When monitors override the settings of Collection Services to gather performance data more frequently, the settings are not undone when a monitor stops. You must manually change the Collection Services settings if you no longer want to collect the data as often.
The following steps show you how to enable system monitor data collection from the Performance tasks in IBM Navigator for i:
1. From IBM Navigator for i, click Performance  All Tasks  Collectors  Collection Services  Configure Collection Services, as shown in Figure 2-71.
Figure 2-71 Configure Collection Services
2. In the Configure Collection Services - General window (Figure 2-72), select the Enable system monitoring option.
Figure 2-72 Enable system monitoring
3. You can also configure data retention, as shown in Figure 2-73.
Figure 2-73 Configure data retention
4. It is also possible to configure the system monitor categories, as shown in Figure 2-74.
Figure 2-74 System monitor categories customization
Differences with Management Central monitors
IBM Navigator for i system monitors and Management Central monitors are two separate functions.
Management Central monitors (that uses the IBM i Navigator client) still work and run against an IBM i 7.2 system.
Both system monitor functions have dependencies on Collection Services to control what data is collected and at what interval:
Management Central uses application override support, which can allow any of the Collection Services data categories to be collected more frequently than what is specified for the configured collection profile.
IBM Navigator for i system monitors the usage of the new system monitoring settings that are specified by the Configure Performance Collection (CFGPFRCOL) CL command or in the Configure Collection Services GUI in IBM Navigator for i.
Management Central gets and stores the monitor data differently than the IBM Navigator for i system monitoring support:
Management Central stores the monitor data in private *MGTCOL objects.
IBM Navigator for i system monitors the usage of the monitor data that is exported by Collection Services into DB2 files with file names starting with QAPMSM*.
 
Note: IBM Navigator for i system monitor functions do not work when an IBM 6.1 or 7.1 target system is specified. The underlying Collection Services support is available only in Version 7.2.
2.1.9 Performance
This section explains the enhancements in IBM Navigator for i that are related to performance tasks. The IBM Navigator for i performance interface includes PDI, Collection Manager, and web-based GUI interfaces for Collection Services, Job Watcher, and Disk Watcher. New functions for Batch Model, System Monitor, and Performance Reports are described in this section.
The following topics are covered in this section:
Performance data reports
A performance data report can be generated for a set of PDI perspectives. You can view the report in IBM Navigator for i or generate a PDF or compressed file. By using performance data reports, you can efficiently export multiple charts or tables for a collection at one time.
For performance data reports, as shown in Figure 2-75, users can perform the following operations:
Add a definition.
Delete a definition.
Add definitions by using existing definitions.
View report definitions.
Figure 2-75 Performance data reports tasks
Figure 2-76 shows an example of a performance data report definition.
Figure 2-76 Performance data report definition example
Drill-down information
In PDI, users are allowed to view additional information, which is shown in the blue title bar of the window. This is referred to as drill-down information. To view the drill-down information, users must select the intervals and do the drill-down action. Additional information in the blue title bar for the drilled-down chart shows what parameters are used for that specific drill-down information.
Figure 2-77 shows the drill-down information when selecting data in PDI.
Figure 2-77 Drill-down information in the Performance Data Investigator title bar
System Information pane
In the PDI perspectives display window, the Show System Information view option provides more detailed information for the system from which the displayed collection came. This includes information such as processor, memory, and partition specifications.
Figure 2-78 shows the System Information pane in PDI.
Figure 2-78 System Information pane in PDI
Show SQL error messages option
The Show SQL error messages option in the Options pane in PDI provides specific error information about SQL errors when the Modify SQL function is used.
Health indicators
The Health Indicators perspective for database health was added to the Health Indicators package.
For more information that is related to the health indicators, see Accessing IBM i Health Indicators Using Performance Data Investigator, REDP-5150.
Batch model
IBM Navigator for i 7.2 provides the modeling tool for system utilization and run times of
IBM i batch workloads, which is useful for analyzing and predicting batch job performance on IBM i, and helps users to know what improvements that they can do to meet a certain batch window target.
Here are the functions of the batch model in IBM Navigator for i:
Helps users to optimize workloads by locating times during the batch window when more efficient job scheduling can improve total system throughput.
Models workload increments.
Predicts the changes in throughput that results from hardware upgrades (processor or disk).
Predicts run times for individual workloads and the overall batch window.
Models batch workloads that are CPU- or disk-intensive.
 
Note: The batch model functions and content package require the installation of IBM Performance Tools for i (5770-PT1) Option 1 - Manager Feature.
To open the batch model function in IBM Navigator for i, click Performance → All Tasks → Sizing → Batch Model, as shown in Figure 2-79.
Figure 2-79 IBM Navigator for i Batch Model tasks
 
Note: You can also view any batch model collections in the main table under the Manage Collections options. It is also possible to use the Create Batch Model function from the Action menu under Manage Collections when selecting a valid CS collection.
Batch model collection is created based on existing performance data that is collected by Collection Services. During the process of creating a batch model, the measured data is analyzed and a model is built over the measured data.
To create a batch model, click Performance → All Tasks → Sizing → Batch Model → Create Batch Model. The Create Batch Model window opens, as shown in Figure 2-80. Specify the collection name and the library where the performance collection data is and click OK.
Figure 2-80 Create a batch model
 
Note: The Create Batch Model action submits a batch job to create the model. It can sometimes be a long-running operation. The creation is done when the status of the Batch Model collection is in a Complete state.
To check the status of a batch model creation, click Performance → All Tasks → Sizing → Batch Model → Batch Models. After the batch model creation finishes, it shows a Complete status, as shown in Figure 2-81.
Figure 2-81 Completed batch model creation
A batch model provides the facility to change the calibration of batch model measured data if it was modeled incorrectly by the system. To do so, click Performance → All Tasks → Sizing → Batch Model → Change Model Calibration. Specify the batch model name to be changed and click OK. Users are allowed to change the storage and workload for batch model calibration. See Figure 2-82.
Figure 2-82 Change a batch model calibration
 
Note: After changing the calibration of a batch model, users are required to perform a Calibrate Batch Model action so that the system can re-create the model after the calibration changes. To calibrate the batch model, click Performance → All Tasks → Sizing → Batch Model → Calibrate Batch Model. Similar to creating a batch model, calibrating a batch model submits a batch job to re-create the model and can be a long-running operation.
You can use a batch model to change the batch model to model various “what if” scenarios. Users can change a batch model to the following scenarios:
Overall system workload growth
Processor upgrade
Disk upgrade
Changes to individual workloads
To specify the above “what if” changes, click Performance → All Tasks → Sizing → Batch Model → Batch Models, right-click the batch model result, and select Change Model. In the Change Batch Model window (Figure 2-83), specify the changes to the batch model and then click OK to apply the changes.
Figure 2-83 Change a batch model
As shown in Figure 2-84, you can start investigating the completed batch model by right-clicking the batch model and selecting Investigate Results.
Figure 2-84 Start a batch model investigation
Figure 2-85 shows the investigation result of a batch model. The diagram shows the Measured Workload Timeline Overview, which describes the measured performance data that is collected in the Collection Services.

EIM configuration
The EIM configuration includes the following items:
EIM configuration wizard
Configuration list
Configuration actions
The configuration wizard guides you through the configuration of the system to participate in an EIM domain.
EIM domain management
The EIM domain management describes all objects and actions that are related to the EIM domain, which includes the Domain folder actions, the User Registries subfolder actions, the Identifier subfolder actions, the User Registry object actions, and the Identifier object actions.
2.1.12 Omnifind Text Search
The ability to search text from files in the integrated file system (IFS) and spooled files in output queues was added to IBM Navigator for i for IBM i 7.2. To use this function, click System → Search, as shown in Figure 2-106.
Figure 2-106 Omnifind Text Search
 
Note: The IBM OmniFind® product (5733-OMF) must be installed on the system to use this function.
In IBM i 7.2, OmniFind supports indexing the files from the top level of the directories and from the subdirectories of the directories recursively. From IBM Navigator for i, there is the possibility to search text from IFS and spool files without needing to understand stored procedures.
For more information about OmniFind Text Search, see 8.9, “OmniFind Text Search Server for DB2 for i” on page 412 and IBM Knowledge Center:
2.1.13 Disk management
In IBM Navigator for IBM i 7.2, the concurrent removal of disk units can be enabled from an ASP and from an IASP that is varied on.
After selecting the disk unit, you are prompted to confirm its removal from the ASP, as shown in Figure 2-107.
Figure 2-107 Confirmation of the concurrent removal of a disk unit from an ASP
After the removal is started, you can perform the following actions, as shown in Figure 2-108:
Pause
Resume
Cancel
Figure 2-108 Removal of disk units from ASP: available actions
You also can pause the disk unit removal process and afterward cancel the running process if necessary, as shown in Figure 2-109.
Figure 2-109 Cancel the disk unit removal process
As shown in Figure 2-110, a Solid State Drive column was added to the disk units list to indicate whether the disk unit is a solid-state drive (SSD). Previously, you could not find the SSD information from the type and model of some drives.
Figure 2-110 Solid State Drives column
In IBM Navigator for IBM i 7.2, some of the user access restrictions on IBM Navigator for i were removed, which means users can have a different user ID and password for IBM i and within System Service Tools (SST), as shown in Figure 2-111.
Figure 2-111 Service tools: disk management tasks access
 
Note: In IBM i 7.2 IBM Navigator for i, a user can access the disk management tasks in the same way they do in IBM i Navigator, that is, by using a service tools user that is independent from the IBM i profile that is used to sign on to the system.
If you have a matching service tools user ID and IBM i user ID, the sign-on window does not open and you access the disk management functions as usual. If that fails, a sign-on window opens asking for the service tool user ID and password.
The first time that you access disk management functions, if your service tools user ID and password do not match your IBM i user ID and password, the sign-on window opens. After you get access to the disk management functions, you do not need to sign on again, even if you log out and log in. If your service tools user ID or password is changed or expired, when you access disk management interface, an error message is displayed and the sign-on window opens again.
As shown in Figure 2-112, the following actions were added for disk pools:
Start tracing.
Stop tracing.
Clear trace.
Start balance.
You can use these actions to trace the hot data on each disk unit in the specific disk pool and balance them in the disk pool by different balance types.
Figure 2-112 Disk pool menu
As shown in Figure 2-113, the rebuild disk unit data action is added for disk units, which users can use to rebuild data on a failed disk unit within a parity set.
Figure 2-113 Rebuild disk unit data: failed disk within RAID protected set
The following options are available for the user, as shown in Figure 2-114:
Stop allocating data on specific disk units.
Resume allocating data on specific disk units.
Figure 2-114 Stop and resume allocating data to disk units
2.1.14 Partition management
Within IBM Navigator for i, you can now perform the following partition management tasks:
Create a partition.
Work with existing partitions.
Creating a partition
In IBM Navigator for i 7.2, you can create a partition, as shown in Figure 2-115, by clicking Configuration and Service  Create Partition.
Figure 2-115 Create a partition
This starts the Create Partition Wizard, where you can define the partition properties (Figure 2-116).
Figure 2-116 Create Partition Wizard
From the Create Partition Wizard, you can define the following parameters for the partition:
General: Specify the partition ID, partition name, and partition type (IBM i or Linux).
Memory: Specify the memory to be assigned to the partition. The minimum memory that is needed for a partition to complete successfully an IPL is 128 MB. The maximum allowed memory is the current available memory. Partitions must have memory that is assigned in multiples of the memory region size.
Processors: Specify the number of processors and the processing mode (dedicated or shared processor pool).
Ethernet: Configure the virtual Ethernet setup.
Storage: Select the virtual disk to be assigned to the partition.
 
Note: Virtual Partition Manager (VPM) does not provide the function of assigning the storage resource to the new partition, such as virtual disk, optical device, and physical disks. You must use the Create Network Server Description (Create NWSD) CL command for the new partition and then link the storage device to the new partition by using the Add Server Storage Link (ADDNWSSTGL) CL command.
Working with partitions

2.1.16 Integrated server administration
The following enhancements that are related to the integrated server support were added to IBM i 7.2:
Resource allocation priority
The resource allocation priority is used to define the cost of the hosting IBM i resources when formatting the storage spaces that are linked to the client servers.
In IBM i 7.2, when the resource allocation priority parameter is used the Create NWS Storage Space (CRTNWSSTG) CL command, it defines a range of 1 - 9 to indicate how many resources should be given to the process that zeros out the disk during a format request:
A lower value requires more time to complete a format, but consumes fewer resources from the host system.
A higher value completes the format faster, but consumes more resources on the host system.

In IBM i 7.2, support for Windows Server 2003 was removed.
 
Note: No new integrated Windows Server 2003 (and R2) servers can be installed or cloned in IBM i 7.2. Integrated Windows Server 2003 (and R2) servers that were installed on prior IBM i releases and then migrated to IBM i 7.2 can continue to run as is, but without service support. The suggested migration path for these servers is to upgrade to Windows Server 2008 or newer version.
Creating quorum disks function removed
In IBM i 7.2, the ability to create quorum disks was removed.
No support for IXS and IXA hardware
With IBM i 7.2, Integrated xSeries Server (IXS) and System x servers that are attached by using the Integrated xSeries Adapter (IXA) are no longer supported.
Integrated server cloning
Support was added to select the storage pool where virtual storage should be created. See Figure 2-131.
You can specify where the storage space should be created:
Auxiliary storage pool ID: Select an ASP ID 1 - 255.
ASP device: Specify the ASP device name in case there is an Independent ASP.
 
Note: Data offset is used to specify how IBM i should align the disk, that is, either align the first logical partition or logical disk. For *ReFS, use the default align first logical partition (*ALIGNLGLPTN), which is the same as the NTFS format.

Deployment wizard for easy customization and deployment
In a large-scale deployment, it is hard for the IT administrators to deploy IBM i Access Client Solutions and customize its functions on a large number of PCs. Therefore, a deployment wizard feature was added to provide simplicity of customizations and deployments. This deployment wizard leads the administrator through a series of questions, asking which function should be available for users.
IBM i Access Client Solutions wizards are inside the Windows_Application directory and are named as follows:
install_acs_32.js for the 32-bit version of Windows
install_acs_64.js for the 64-bit version of Windows
There are two types of IBM i Access Client Solutions deployments:
Local deployment
Local deployment means that the product files must be copied and stored on the PC where the product will be deployed.
Remote deployment
Remote deployment means that the product files are not copied to the PC. Instead, they are accessed remotely from the PC, which means that the product files can be shared by multiple users.
Customization and deployment of IBM i Access Client Solutions can be done in the following ways, depending on the user requirements:
1. Local and user customized
The IBM i Access Client Solutions product files are copied and locally stored in each user PC and each user decides which functions are available for themselves.
2. Local and administration customized
The IBM i Access Client Solutions product files are copied and locally stored in each user PC, but instead of the users, the PC administrator decides which functions are available for the users.
3. Remote and administration customized
The IBM i Access Client Solutions product files are accessed from a shared central location (for example, IFS directories and network shared drives) and the PC administrator decides which functions are available for the users.
To customize easily the installation of IBM i Access Client Solutions, the installation package comes with an editable configuration file that is named AcsConfig.properties. This file contains the properties of configuration, which enables the administrator to determine several preferences of how IBM i Access Client Solutions are deployed to the clients. This configuration file also provides examples that guide the administrator to modify the preferences easily.
The properties that are available include the following ones:
com.ibm.iaccess.AcsBaseDirectory, which determines the configuration location
com.ibm.iaccess.ExcludeComps, which is used to restrict the usage of specific functions to be deployed
com.ibm.iaccess.Fonts, which enables the administrators to override the default font setting
com.ibm.iaccess.autoimport, which is used to set up automatically a configuration for new users or to update a configuration for existing users
Example 2-1 shows the usage of the AcsConfig.properties file to exclude several functions and modify the default font path in an IBM i Access Client Solutions deployment.
Example 2-1 Example of a configuration in the AcsConfig.properties file
com.ibm.iaccess.ExcludeComps=KEYMAN,OPCONSOLE,HWCONSOLE,L1CPLUGIN
com.ibm.iaccess.Fonts=/Users/IBM_ADMIN/MyFonts

For more information about Application Runtime Expert for i, see the following publications:
Uncovering Application Runtime Expert - IBM i 7.1, REDP-4805
IBM i 7.1 Technical Overview with Technology Refresh Updates, SG24-7858
2.4 Journal management
This section describes the journal enhancements that are implemented in IBM i 7.2. The following topics are covered:
2.4.1 STRJRN parameter for restore CL commands
A new parameter called Start journaling (STRJRN) was added to Restore Object (RSTOBJ) and Restore Library (RSTLIB) CL commands. This parameter controls whether the journaling is automatically started for the new objects after restore. Journal information that was saved is restored regardless of the value of the parameter. Existing objects are not affected. This parameter takes precedence over QDFTJRN data area and journal inheritance.
2.4.2 Deferred journal restore
In IBM i 7.2, restore processing is enhanced to allow the start of journaling to be deferred for database files, data areas, data queues, and libraries when the object or library is restored before the journal. After the journal is restored, the object that deferred start of journaling is reestablished and resumes journaling.
To use this feature, you must specify the Defer ID (DFRID) parameter on the restore operation. The DFRID parameter is an optional parameter for the Restore Library (RSTLIB) CL command, Restore Object (RSTOBJ) CL command, and Restore Object List (QSRRSTO) API. Currently, the DFRID parameter is used to defer the restore of views (logical files) and materialized query tables (MQTs) that are restored before they are being based on files. This enhancement allows the Defer ID support to be used to defer starting journaling on an object.
To use explicitly this enhancement, the new Restore Deferred Objects (RSTDFROBJ) CL command can be called directly by using the same Defer ID (DFRID) value that was used with the RSTOBJ or RSTLIB CL commands.
The following restore operations are configured to use the Defer ID support:
GO RESTORE option 21
Start Recovery by using the BRM (STRRCYBRM) CL command
For more information about deferred journal restore, see Deferred Journal Restore topic in the IBM i Technology Updates website:
2.4.3 Secure remote journal
Starting in IBM i 7.2, remote journaling now acknowledges the secure connection field in a Relational Database (RDB) Directory Entry panel (ADDRDBDIRE and CHGRDBDIRE CL commands). Secure remote journaling uses the default TCP/IP port 3889 and the cipher that is defined in Digital Certificate Manager under the application ID:
IBM i Remote Journaling Source (as application client)
IBM i Remote Journaling Target (as application server)
 
Note: To make secure remote journaling work, both the source and the target systems must be at IBM i 7.2.
Depending on the cipher that is used under DCM, a performance impact and a remote entry synchronization delay can occur.
For more information about secure remote journaling, see IBM Knowledge Center:
2.4.4 QJOSJRNE API change
The force journal entry key now accepts a new value of 2, which means that the journal receiver is forced to auxiliary storage, but no journal entry is sent.
For more information about the Send Journal Entry (QJOSJRNE) API, see IBM Knowledge Center:
2.4.5 Journal conversion after an IBM i 7.2 installation
After IBM i 7.2 is installed or updated, a Change Journal (CHGJRN) CL command is issued once for all journals on the system. This action supports a conversion, which is required for internal information of the journal and journal receiver objects.
2.4.6 Journal limits changes
The following journal limits changes were implemented in IBM i 7.2:
The maximum number of journal receivers that are allowed in a range of receivers on a journal command was increased from 1024 to 2045.
The maximum number of active commitment definitions with object-level changes that can be processed concurrently by an APYJRNCHG or APYJRNCHGX CL command was increased from 1023 to 32767 if commitment control if already active.
The maximum number of journal receivers that can be associated with one journal was added and its value is 131036.
For more information about journal limits, see IBM Knowledge Center:
2.4.7 New journal entry types
The following new journal entry types were added in IBM i 7.2:
D code new types (row and column access control):
 – M1 for create mask
 – M2 for drop mask
 – M3 for alter mask
 – P1 for create permission
 – P2 for drop permission
 – P3 for alter permission
T code new types (audit journal):
 – X2 for query manager profile changes
 – AX for row and column access control
 – PF for PTF operations
 – PU for PTF object changes
For more information about journal entry codes and types, see IBM Knowledge Center:
2.4.8 Displaying journal information
This section describes the changes that were made in IBM i 7.2 to retrieve journal information more easily.
Journal information for a table on IBM Navigator for i
IBM Navigator for i has been extended with an option to display journal information for a table. A new menu option that is called Journaling was added to the menu of the Tables window, as shown in Figure 2-185.
Figure 2-185 Journaling information that is available for a particular table in the Tables window
The Journaling menu option opens a detailed journaling information window for the selected table, as shown in Figure 2-186.
Figure 2-186 Detailed journaling information for a database table
You can now view journal entries by using IBM i Navigator for i. The Journals window was enhanced with a new menu option called View Entries for a selected journal, as shown in Figure 2-187.
Figure 2-187 New View Entries menu option in the Journals window
The View Entries menu option opens the Journal Viewer window, where you can filter and present journal entries for the selected journal, as shown in Figure 2-188. Viewing entry-specific data is also possible in from this window.
Figure 2-188 Journal Viewer window
For more information about displaying journal information for a table by using IBM Navigator for i, see IBM Knowledge Center:
Display_Journal table function
You can use the QSYS2/Display_Journal SQL table function to view journal entries. This function is more efficient than displaying journal entries to an output file by using the Display Journal (DSPJRN) CL command and then querying the resulting file.
For more information about the QSYS2/Display_Journal SQL table function, see
IBM Knowledge Center:
2.4.9 Journal Sizing and Planning tool
The Journal Sizing and Planning tool is available for IBM i 7.2. This tool can be used to determine the amount of additional I/O workload that might be generated by journaling one or more database files.
 
Note: The Journal Sizing and Planning tool predicts workloads only for database files and not for any other object types.
For more information about downloading and using the Journal Sizing and Planning tool, search for Journal Sizing and Planning Tool at the following website:
2.5 Work management enhancements
This section describes the following IBM i 7.2 work management enhancements:
2.5.1 Temporary storage enhancements
Temporary storage in IBM i system, also called unprotected storage, is a place in the system storage where programs, running under jobs and system functions, put objects that are required during run time. It is used to keep automatic, static, heap, and teraspace storage for programs, temporary objects that are created by programs either for a single job or reused across multiple jobs, or working storage for the Licensed Internal Code (LIC) to support the operating system. Temporary storage is reclaimed on each IPL.
IBM i 7.2 introduces significant temporary storage enhancements, which allows for accurate temporary storage usage tracking system-wide and at a job level. The following sections describe the new features that are related to temporary storage in IBM i 7.2:
Storage management buckets
Before IBM i 7.2, retrieving information about temporary storage that is used by the system or a particular job was not easy and often required using multiple tools or IBM support. The information might have been misleading or inaccurate, especially when the storage was allocated by one job or task and then returned by another one.
In IBM i 7.2, storage management was changed to use new buckets to collect storage usage information. The buckets track temporary storage for the following tasks:
Scoped to a single job
Scoped to multiple jobs
Scoped to the system
For LIC allocations (so-called “no charge”)
For allocations that persist after a job ends
The total value of all buckets should match to the Current temporary storage value on the Work with System Status (WRKSYSSTS) panel.
Figure 2-191 on page 170 shows temporary storage in megabytes that is used by the system.
The SYSTMPSTG file in the QSYS2 library can be queried for the current size of all available storage buckets on the system as shown in Example 2-2. Running an SQL query over this file is a quick way to find the biggest temporary storage consumers during a problem determination situation.
Example 2-2 Display the content of temporary storage buckets in the SYSTMPSTG file

Temporary storage limits
As in previous releases, maximum temporary storage for a job can be controlled by the MAXTMPSTG parameter in the class description (CRTCLS and CHGCLS CL commands). In IBM i 7.2, the same parameter was added to the Change Job (CHGJOB) CL command, allowing a user to change that limit after the job starts.
To change the maximum temporary storage limit for a job to 20 MB, substituting NUMBER, JOBUSER, and JOBNAME with proper values, run the following CL command:
CHGJOB JOB(NUMBER/JOBUSER/JOBNAME) MAXTMPSTG(20)
This parameter is especially useful with changed system behavior when a job reaches the maximum temporary storage limit. IBM i 7.2 now holds the job, instead of ending it. You are given the opportunity to examine the held job and decide whether it should be ended, released, or investigated further. You can use the CHGJOB CL command to extend the temporary storage limit and release the job for further execution.
When a job reaches the maximum temporary storage limit, a new CPI112E message is sent to QHST and the job’s job log, as shown in Figure 2-198.

To avoid this condition in the future, use the Change Class (CHGCLS)
command to specify a larger MAXTMPSTG value or use the Change Routing Entry
(CHGRTGE) command to specify a different class.

Control Temporary Storage API
IBM i 7.2 introduces a new Control Temporary Storage (QWCCTLTS) API. You can use this API to do the following tasks:
Set the temporary storage notification threshold for system ASP as a percentage of the total system ASP.
Set the temporary storage notification threshold for a specific storage bucket in megabytes or gigabytes.
Reset a previously set threshold.
Display a current threshold value.
Exceeding the threshold for system ASP triggers a new CPF090A message, as shown in Figure 2-199.

2.5.2 PTF-related changes
This section describes the following IBM i 7.2 PTF-related changes:
Conditional immediate PTFs
In IBM i 7.2, there is now something called conditional immediate PTFs.
PTFs are identified with a type of either delayed or immediate. A delayed PTF must be applied or removed during IPL. An immediate PTF can be applied or removed either while the system is active or during IPL.
Before IBM i 7.2, when a new PTF superseded a delayed PTF, the new PTF was required to be delayed even if only immediate parts or objects are being changed or added. Within IBM i 7.2, you can now have superseded PTFs immediately applied when only immediate parts or objects are being changed. When the PTF is applied or removed, PTF management determines whether the PTF can be applied or removed immediately or not, depending on whether the most recent delayed superseded PTFs are permanently applied.
The Display Program Temporary Fix (DSPPTF) CL command adds an option 12 (Delayed superseded PTFs) to the Display PTF Details panel for delayed superseded PTFs, as shown in Figure 2-201.

Figure 2-202 Display Delayed Superseded PTFs
The QPZRTVFX API supports a new format PTFR1100 to return the list of delayed superseded PTF IDs for a conditional immediate PTF.
For OUTPUT(*PRINT), the new delayed superseded PTFs section was added to the spool file.
 
Note: A conditional immediate PTF is not identified by a new type (immediate or delayed), but rather by the presence of the new delayed superseded PTFs list. This new list is used at apply and remove time to determine whether the PTF can be applied or removed immediately or if the operation must be delayed. This is consistent with immediate PTFs that specify delayed prerequisite PTFs. If the delayed prerequisite PTFs have a status of temporarily or permanently applied, the dependent PTF can be applied immediately. Otherwise, the dependent PTF is set for delayed apply. Also, if an immediate PTF has preconditions that are not satisfied, the PTF is set for delayed apply.
Display PTF Apply Information (DSPPTFAPYI) CL command
The Display PTF Apply Information (DSPPTFAPYI) CL command indicates whether the selected PTFs can be applied immediately from *SERVICE. All selected PTFs and their prerequisite PTFs that are not applied are displayed. If a PTF has a status of Superseded, the PTF it is superseded by is displayed in place of the superseded PTF.
Each PTF that is displayed has the Apply Type field set to one of the following statuses:
*IMMED: The PTF can be applied immediately. For Licensed Internal Code (LIC) PTFs, the PTF installation must be done from the ##MACH#B IPL source.
*DELAYED: The PTF requires an IPL to apply because it has a PTF type of delayed.
*PRECND: The PTF can be applied immediately if all of its preconditions are met.
*ACTRQD: The PTF has an action that is required if the selected PTFs are installed.
*DLYSPR: The immediate PTF requires an IPL to apply because it supersedes a delayed PTF that is not temporarily or permanently applied.
*REQIPLRQD: The PTF has a prerequisite PTF that requires an IPL to apply.
*REQPRECND: The PTF has a prerequisite PTF that has a precondition.
The selected PTFs and prerequisite PTFs that will be installed must exist in *SERVICE. Save files must exist for the selected PTFs that have not been loaded. The specified PTF group must exist on the system along with its PTFs and prerequisite PTFs that are not yet installed.
If the PTFs and PTF groups are on physical media or in an image catalog, use one of the following methods to copy the PTF save files and PTF groups into *SERVICE before running this command:
Use the QPZCPYSV API to copy the PTF save files and PTF groups into *SERVICE.
Use the Copy PTF (CPYPTF) CL command to copy the PTF save files from media into *SERVICE. Use the Copy PTF Group (CPYPTFGRP) CL command to copy the PTF groups into *SERVICE.
 
Note: This command is shipped with exclude (*EXCLUDE) public authority, and the QPGMR, QSYSOPR, QSRV, and QSRVBAS user profiles are shipped with private authorities to use this command.
2.5.3 IBM i command changes
This section describes changes that are made to the following IBM i 7.2 commands:
Create Image Catalog (CRTIMGCLG) CL command
The Create Image Catalog (CRTIMGCLG) CL command can now add all .ISO and .BIN image files from the image catalog directory to the image catalog as virtual volumes.
To do this task, use the *DIR value for the ADDVRTVOL parameter and *ALL for the IMGTYPE parameter. Other options for the IBMTYPE parameter include the following ones:
*BIN for all binary images
*ISO for all ISO images
For more information about the Create Image Catalog (CRTIMGCLG) CL command, see
IBM Knowledge Center:
Other command changes

2.6 Operating system limitation changes
Various system limitations were changed in IBM i 7.2. Exceeding system limits can cause application or system outages. Be aware of these limitations during system planning, configuration, and application design.
For more information about current system capacities, see IBM Knowledge Center:
2.7 IBM Advanced Job Scheduler for i
IBM i 7.2 provides several enhancements of IBM Advanced Job Scheduler for i, especially for integration with IBM Navigator for i. The enhancements in IBM Navigator for i that are related to IBM Advanced Job Scheduler for i include the following ones:
Support for configuring application/job controls, library lists, command variables, permissions, data libraries, and calendars in the Advanced Job Scheduler properties.
Work Flow Manager added for workflow management.
2.7.1 Advanced Job Scheduler properties
In IBM 7.2, IBM Navigator for i provides more configurations in the Advanced Job Scheduler properties.
To access the Advanced Job Scheduler properties from IBM Navigator for i, click Work Management → All Tasks → Advanced Job Scheduler → Properties.
 
Note: For more information about accessing IBM Navigator for i, see 2.1, “IBM Navigator for i” on page 14.
As shown in Figure 2-203, there are several new tabs that are now available in IBM Navigator for i that are related to Advanced Job Scheduler:
Figure 2-203 Advanced Job Scheduler Properties in IBM Navigator for i
Job Controls/Applications
Applications are jobs that are grouped for processing. Job controls are the defaults that are assigned to a job when you add it to the job scheduler. Job control defaults include such things as default application, calendar, and holiday calendar. Each application contains job control information. The application that is specified in the definition of a job is used to determine the job controls that are used by the job when the job is submitted. If the job does not contain an application, the job uses the job controls in the system default.
Figure 2-204 shows the Job Controls/Applications tab in the Advanced Job Scheduler Properties. You can create, delete, and modify the job control on this page.
Figure 2-204 Job Controls/Applications page in the Advanced Job Scheduler properties
Library Lists
Library Lists (Figure 2-205) contains user-defined lists of libraries that are used by an Advanced Job Scheduler job when it is processing. From this window, you can add a library list, add a library list based on an existing one, or remove a library list, if it is not being used by a scheduled job. You can also select a list and display its properties to make changes.
Figure 2-205 Library Lists window in the Advanced Job Scheduler properties
Command Variables
As shown in Figure 2-206, you can use the Command Variables window in Advanced Job Scheduler Properties to display all the existing command variables on the system. Command variables are variables that can be stored in Advanced Job Scheduler and used in jobs that are submitted through Advanced Job Scheduler. Examples of command variables include the beginning of each month, a division number, a company number, and so on. From this page, you can add variables, add variables based on existing ones, and remove or modify them.
Figure 2-206 Command Variables window in the Advanced Job Scheduler properties
Permissions
You can use the Permissions window to add or modify permissions for functions.
Figure 2-207 shows the Permission window with various default functions whose authorities can be changed for the Advanced Job Scheduler. The name of the function and a description is shown. If your user profile has the proper authority, you can add, remove, or edit the authorities for functions. If not, you can still view the function authority properties, but cannot change them.
Figure 2-207 Permissions window in the Advanced Job Scheduler properties
Data libraries
The data libraries in IBM Navigator for i are enhanced with several new parameters that you can use to specify easily new data library parameters that are used for the Advanced Job Scheduler. The new parameters are Initial ASP group and ASP device, as shown in Figure 2-208.
You can use these enhancements to specify the initial ASP group and ASP device where your library is.
Figure 2-208 New Data Library enhanced parameters
Calendars
In addition to holiday calendar access in IBM Navigator for i in previous releases, you can use IBM Navigator for i V7.2 to also access the fiscal calendar from the web. A fiscal calendar is a calendar of selected days that can be used by users for scheduling a job or a job group. Users can configure their start and end dates for each period in the fiscal year on this web page.
Figure 2-209 shows the Fiscal Calendars page in Advanced Job Scheduler Properties.
Figure 2-209 Fiscal Calendars page in the Advance Job Scheduler properties
2.7.2 Work Flow Manager
Scheduling a job in IBM Advanced Job Scheduler for i is more enhanced in IBM i 7.2 because IBM Navigator for i now provides a feature that you can use to specify a predecessor and successor of each Advanced Job Scheduler job. This feature is called Work Flow Manager. In Work Flow Manager, you can define units of work that consist of automated or manual steps that can then be scheduled or run interactively.
Each step within the work flow can have one or more predecessor Advanced Job Scheduler jobs and one or more successor Advanced Job Scheduler jobs. When a work flow starts, the first step is flagged to run. When it completes, the next step is flagged to run.
There are several considerations when you use Work Flow Manager:
You can manually start a work flow at any step. When you do so, you bypass all previous steps in the work flow.
Automatic steps complete after all prior steps complete, which includes all predecessor Advanced Job Scheduler jobs.
After a step completes, the successor Advanced Job Scheduler jobs are flagged to run.
Manual steps can complete in any sequence after the step’s predecessor jobs complete.
You can mark completed manual steps as not complete and run them again after there are no subsequent incomplete automatic steps.
You can cause a step to wait until the job completes by specifying predecessor jobs that are the same as the successor jobs of the previous step.
You can notify other users when a particular step starts, stops, did not start by a specific time, or is taking too long. For example, you can notify a user who is responsible for a particular manual step that the previous automated steps complete.
Figure 2-210 shows the Work Flow Manager page in IBM Navigator for i. It displays all the existing work flows in the system.
To display the Work Flow Manager, click Work Management → All Tasks → Advanced Job Scheduler → Work Flow Manager → Work Flow Manager.
