NOTE: GlancePlus does not correctly track the PRM ID at the process level for HP-UX 11i v1
and later in versions C.02.65.00 through C.03.25.00. For correct metrics reporting for FSS PRM
groups, use GlancePlus Version C.03.35.00.
Also, GlancePlus returns incorrect data for the PRM_SYS group for PRM configurations with processor
sets defined. Use the prmmonitor command instead of GlancePlus if you are using PSET PRM
groups.
1. Load the PRM configuration you want to analyze with prmconfig -ie APPL if it is not
already loaded. This allows you to view the PRM Group List under the Reports menu in
GlancePlus.
2. Compare the PRM resource shares against the reported usage in GlancePlus during peak
activity. Select the PRM Group List under the Reports menu to see the active processes, users,
and their resource use. Determine if you need to adjust the shares or move users or processes
to different groups.
3. Change your PRM configuration based on your review of the GlancePlus data.
4. Load the changed PRM configuration with prmconfig -ie APPL. This load places processes
in the owners’ initial groups and each configured application in its assigned group.
5. Repeat Step 2, Step 3, and Step 4 as needed.
For information on using GlancePlus, see the GlancePlus online help.
Here is a sample of the GlancePlus information on PRM.

Analyzing memory use
The following steps guide you in using PRM’s logging facility to examine system memory use.
1. Load a PRM configuration with prmconfig -ie APPL if you have not already done so. Do
not enable the PRM resource manager at this time. (You can disable PRM with the prmconfig
-d command if it is already enabled.)
2. Log PRM memory messages by entering:
# prmconfig -L MEM
