This should help to locate potential performance problems or to fine-tune the configuration.
Glance and MeasureWare are also aware of PRM groups. In Glance you can access the PRM
screen by pressing key āPā.
Modifying the Configuration
If it seems that the chosen entitlements need to be tuned, then the PRM configuration can be
changed online, i.e. without stopping any processes. After modifying the configuration file
/etc/prmconf the changes can be applied immediately.
Modify the current configuration:
# vi /etc/prmconf
Check the configuration file:
# prmconfig -c
Load the configuration using one of the commands below:
To initialize, moving user processes to the ownersā initial groups and moving applications to
their assigned groups, use the command:
# prmconfig -i
To keep the existing assignments of users, processes, and groups, use the command:
# prmconfig -k
