B Configuring HP Process Resource Manager
groups on HP-UX hosts
Process Resource Manager (PRM) provides an efficient and flexible way to manage resource allocation
at times of peak system load. It gives you the ability to group users or processes together and guarantee
each group the minimum amount of the total CPU, real memory, and disk bandwidth available.
Installing HP Process Resource Manager
PRM is installed using the Software Distribution (SD) utility. Installation of PRM typically requires a
kernel build and a reboot of the system. For more specific information, see the release notes available
in the /opt/prm/newconfig/RelNotes/ directory. During installation, a minimal /etc/prmconf
file is created and then PRM is unconfigured and disabled allowing the standard HP-UX resource
management to controls the system. PRM is installed in /opt/prm/.
Using the command-line interface to configure HP Process
Resource Manager
In addition to the HP System Management Homepage (SMH) interface and the HP Systems Insight
Manager (SIM) interface, you can manually create the PRM configuration using a text editor. You
activate the configuration with the prmconfig utility.
To preserve your configuration during reboots, modify the variables in the PRM user specified startup
script /etc/rc.config.d/prm to automatically configure PRM on reboot.
If you do not specify a file, PRM uses the default copy of the configuration file (either /var/tmp/
PRM.prmconf or /var/tmp/PRM.prmconf.old if PRM.prmconf is not present).
Setting PRM to start automatically at reboot
After rebooting your system, PRM is unconfigured and disabled if you have not previously configured
the PRM startup script.
To preserve your configuration across reboots, modify the variables in the PRM startup script /etc/
rc.config.d/prm to automatically configure PRM on reboot. The startup script configures PRM
using the file you specify in /etc/rc.config.d/prm.
If you do not specify a file, PRM uses an internal copy of the previous configuration file (either /var/
tmp/PRM.prmconf or /var/tmp/PRM.prmconf.old if PRM.prmconf is not present).
Examples of configuring Process Resource Manager
The configuration details required for PRM are stored in the /etc/prmconf file.
