The release notes for PRM are in the directory /opt/prm/newconfig/RelNotes.
After PRM is loaded, we have to set the value of variables in /etc/rc.config.d/prm to suit our needs. The variables in this file give you control over such functions as whether or not capping is enabled, configuring PRM on reboot, and other such basic setup functions. These variables are described in both the startup file and User's Guide. You can set all of the variables to 1 to enable everything, or pick and choose which functions you want enabled. The following is a list of the variables with all functions enabled except PRM's SNMP agent:
PRM_CONFIG=1 # PRM configured on reboot PRM_ENABLE=1 # Enable resource managers PRM_CAPPING=1 # Enable CPU capping PRM_SNMPAGT=0 # Don't start PRM's SNMP agent PRM_RMTCONF=1 # Enable PRM remote configuration
The following listing shows the entire contents of the /etc/rc.config.d/prm file.
root@dwdbp1[/.root] > cat /etc/rc.config.d/prm
#!/sbin/sh
#
# PRM configuration. See prmconfig(1)
#
# To configure (and enable) PRM automatically at boot time, PRM must have
# been previously configured. The most recent configuration will be used,
# that is the configuration in place prior to system shutdown or before the
# most recent prmconfig -r (reset).
#
# PRM_CONFIG: Set to 1 to configure PRM
# PRM_ENABLE: Set to 1 to enable PRM
# PRM_CAPPING: Set to 1 to start PRM in CPU capping mode when enabled
# PRM_SNMPAGT: Set to 1, always spawn prmagt at boot time
# PRM_RMTCONF: Set to 1, always spawn remote config daemon at boot
#
# NOTE: in order to use PRM_ENABLE=1, you must set PRM_CONFIG=1
# NOTE: in order to use PRM_CAPPING=1, you must set PRM_ENABLE=1
#
PRM_CONFIG=1
PRM_ENABLE=1
PRM_CAPPING=1
PRM_SNMPAGT=0
PRM_RMTCONF=1
With PRM loaded and running, we can now begin to configure PRM to manage resources.
