Displaying application and configuration information
To display information from the current PRM configuration file, including application record
information, use the prmlist command. This command does not display state information.
#prmlist
PRM configured from file: /etc/prmconf

Setting the memory manager’s polling interval
The memory manager examines the use of memory on a regular basis to ensure PRM groups are
using memory as specified in the configuration. You can change the frequency of these examinations
by changing the polling interval of the manager.
The default polling interval for the memory manager is 10 seconds.
Change the interval on the command line as explained in the following section. You can also
change the interval in the PRM interface in HP System Management Homepage or in HP Systems
Insight Manager.
Setting the interval with prmconfig
To manually change the length of the polling interval, enter the following command, substituting
a numerical value for interval_in_seconds:
#prmconfig -Iinterval_in_secondsMEM
Setting the application manager’s polling interval
The application manager regularly examines all processes on the system to ensure applications
are running in the correct PRM groups. You can change the frequency of these examinations by
changing the polling interval of the manager.
The default polling interval for the application manager is 30 seconds.
Change the interval on the command line as explained in the following section. You can also
change the interval in the PRM interface in HP System Management Homepage or in HP Systems
Insight Manager.
Setting the interval with prmconfig
To manually change the length of the polling interval, enter the following command, substituting
a numerical value for interval_in_seconds:
#prmconfig -Iinterval_in_secondsAPPL
