HP Process Resource Manager (PRM)
HP Process Resource Manager (PRM) provides an efficient and flexible way to manage
resource allocation at times of peak system load. It gives the system administrator the
ability to group users or processes together and guarantee each group minimum
amounts of the total CPU, real memory, and disk bandwidth available.
NOTE Process Resource Manager and HP-UX Workload Manager both make use of the PRM
API. Consequently, only one of the products should be used at a time. (See also “HP-UX
Workload Manager” on page 142.)

PRM version C.02.02 includes the following:
• Many PRM commands now support a version option -V.
•The xprm command now supports SSL encryption of login/password data and xprm
operations (encryption is disabled by default).
If SSL encryption is desired, the customer should read the xprm (1) manpage for
information.
•The prmmove and prmrun commands display data in a wide-column format by default
when you do not specify any options.
•The syslog message is more consistent.
•The prmconfig -k command’s behavior has been modified. (For information on what
groups processes are moved to, see the prmconfig (1) manpage.)
• The disk bandwidth manager is now disabled when not needed by the configuration.
•The prmmonitor command updates its output as expected—even when running in
continuous mode as a nonroot user and a new configuration is loaded.
NOTE PRM is designed to set resource allocations (CPU, memory, disk bandwidth) for
applications. Misconfiguration can result in degradation.
