Figure 4-12 Workload list
As illustrated in Figure 4-12, every time a definition is completed, the wizard shows the new
definition, in this case the new workload just created. Click the Next button (not shown) at the
bottom of the screen to continue with the next definition.
Figure 4-13 Service classes
Tip: You can keep on going through the setup, defining service classes next, and so forth,
but during this process your information is not saved. When using the domain policy
wizard, or any other part of the Control Center for that matter, if you step away from it for
awhile, a logon time-out could occur and the updates are lost. The same loss will occur if
you experience a browser problem. The wizard does not save the updates, so be sure to
enter all information from start to finish before stepping away.
An alternative is to click Finish after creation of workload, and then go through service
class, transaction class, and so forth manually, clicking Finish after you define each
element. Apart from producing incremental saves, there is no difference in defining the
resources in this way; you still follow the panels provided by the wizard.

The screen in Figure 4-13 gives you a place to create service classes. As you can see, as you
proceed in the wizard the elements that have been defined have a check mark and they are
underlined. This means that you can actually select any one of them and edit the individual
definition. You need to continue with the wizard to complete the definition of the elements that
are not yet checked.
The last resource to be defined is the Service policy. When you complete the wizard, click
Apply at the bottom of the screen to save your entries and changes, and then OK to save the
Domain Policy.
Figure 4-14 Saving the Domain Policy
You should receive the message displayed in Figure 4-14 as confirmation that the policy has
been successfully saved. Now you are ready to deploy and activate it.

Chapter 4. Administering EWLM 99
Before EWLM can do anything based on the information just saved within the domain policy,
the domain policy needs to be deployed.
Deployment stages the service policies within the
domain policy for activation. However, only one service policy like the domain policy can be
active at any one time. Figure 4-15 shows the steps to deploy a domain policy:
1. Select the domain policy to be deployed from the list of domain policies.
2. From the action pull-down menu, select the Deploy function.
3. Click Go.
In this example, the domain policy ITSO_Redbook was selected for deployment.
Figure 4-16 Service policy selection
The screen in Figure 4-16 is displayed next. The drop-down menu displays all the service
policies available for activation within the domain policy. In addition, it shows the option of
None. When None is selected, activation of the service policy is done as a second step.
Here, the ITSO_Redbook_NormPol1 service policy is selected to be activated once the
domain policy is deployed. Click Deploy to deploy the domain policy and activate the
selected service policy on all the managed servers.

Figure 4-17 Policy activation
Following deployment and activation, the screen in Figure 4-17 is shown. The first field notes
that the domain policy deployment was successful. The service policy being activated is
identified in the second field. The fields labelled 3 give the details about the service policy,
specifically that activation was successful and that it was successful on all managed servers
(4 of 4).
Adding a service policy
If you want to use several service policies in your environment, for instance at different times
of the week or month, it is easiest to create the additional service policies using the “New
based on...” function. The advantage is that you have all service classes, transaction and
process classes, and all other elements already defined. This includes classification filters as
well as the original goals. All you need to do is to change the goals for this service policy. If
you were to use the “New” function instead, the goals for all service classes would be
discretionary. The method using the New based on function is shown Figure 4-18.

Figure 4-18 Define a Service policy using “New based on”
You need to have a base model service policy: you select the service policy and then the
“New based on..” function from the action pull down menu and click “go”. This creates a new
service policies with the exact definitions of the source one. After the new policy has been
defined, you still need to alter goals within the services classes in order to accommodate
differing workload requirements during the day, weekend, shift, and so forth.
Figure 4-19 Defining a Service policy
Figure 4-19 shows that all the service classes created in the new service policy have the
same goals as the original policy. If you had chosen to use the “New” rather than the “New
based on” function the goals would have been set to discretionary. Because the “New based
on” choice is similar to a copy function, at this point you only need to change the goal for the
service class you are interested in.
