PRM Release Notes Announcement Announcement HP Process Resource Manager (PRM) Version C.03.01 supports the HP-UX 11i (B.11.11) operating systems on HP 9000 servers. It also supports the HP-UX 11i Version 2.0 (B.11.23) operating system running on either HP 9000 servers or HP Integrity servers. HP PRM provides an efficient and flexible way to manage resource allocation at times of peak system load.
PRM Release Notes What’s in this version What’s in this version PRM Version C.03.01 includes the following new features or changes: • Management of shared memory Previously, PRM allowed you to manage only private memory. With PRM C.03.01 on HP-UX 11i v2, you can also manage shared memory. A new record type (#!SHARED_MEM) was introduced for this feature. For information on the new syntax, see the prmconf(4) manpage or the online help.
PRM Release Notes Known problems and workarounds Degraded performance when starting via RC scripts Issue When an initial configuration requesting memory management is loaded (after installing or resetting PRM), PRM initializes memory resource groups (MRGs) giving all usable memory to PRM_SYS initially. Any free memory is then distributed to other PRM groups.
PRM Release Notes Known problems and workarounds No PSET PRM group data from GlancePlus Issue GlancePlus has not been enhanced to recognize processor sets. If you have defined PRM groups based on processor sets in your PRM configuration, GlancePlus returns no information for these PRM groups. Workaround For configurations with processor sets defined, use the prmmonitor command instead of GlancePlus.
PRM Release Notes Known problems and workarounds Alternate names have limit on length Issue Due to a kernel limitation: • On HP-UX 11i v1 (B.11.11), the PRM application manager cannot identify alternate names that are greater than 64 characters in length, or scripts where the combination of the alternate name and command name is greater than 64 characters. • On HP-UX 11i v2 Update 2 (B.11.

PRM Release Notes Known problems and workarounds Secure Resource Partitions: Blocked port on a virtual network interface Issue Using the optional HP-UX feature Security Containment, you can set up a virtual network interface for each secure compartment.
