Compatibility with Shadow Passwords Starting with PRM C.02.03.03, PRM is supported on systems using Shadow Passwords.

PRM Release Notes Known problems and workarounds Application hangs in FSS group with capping enabled Issue On HP-UX 11i v2 (B.11.23), an application inside an FSS group may hang when running in a single-processor virtual partition, nPartition, or system if CPU capping is enabled. Workaround Install patch PHKL_33052. Inconsistent inheritance Issue If a process placed in a PRM group via prmrun, prmmove, or a record spawns child processes, those child processes remain in the same PRM group as the parent.
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 Workaround On HP-UX 11i v3 (B.11.31), be sure to use WBEM Services A.02.05 or later. For HP-UX 11i v1 (B.11.11) and HP-UX 11i v2 (B.11.23), WBEM Services A.02.05 is scheduled for a December 2006 release. Until then, remove trailing spaces in filenames for configuration files you want to use in SMH. For alternate names, use “[ ]*” to handle zero or more spaces; use “[ ]+” to handle one or more spaces. Be careful of spaces used elsewhere.
PRM Release Notes Known problems and workarounds • On HP-UX 11i v2 Update 2 (B.11.23), the PRM application manager cannot identify alternate names that are greater than 128 characters in length, or scripts where the combination of the alternate name and command name is greater than 128 characters. Workaround Be sure these names do not exceed 64 characters on HP-UX 11i v1 or 128 characters on HP-UX 11i v2.
PRM Release Notes Known problems and workarounds Workaround On HP-UX 11i v1 (B.11.11), install patches PHKL_30034, PHKL_30035, PHKL_31993, PHKL_31995, and PHKL_32061. Install all these patches at the same time. For patch descriptions, see “HP-UX 11i v1 (B.11.11) patches” on page 14. These patches address CR# JAGae14311.

PRM Release Notes Known problems and workarounds libprmext “not removed” on PRM upgrade Issue When upgrading your version of PRM, you may see the following message in /var/adm/sw/swagent.log: File “/opt/prm/lib/hpux32/libprmext.so.2” could not be removed. It was renamed and added to the cleanup file “/var/adm/sw/cleanupfile”.
PRM Release Notes Patches and fixes in this version Upgrading or installing PRM before upgrading WLM from C.03.00 or earlier can cause WLM to fail swverify checks Issue If you install or upgrade to the latest version of PRM (C.03.02.xx) on a system with WLM A.03.00 or earlier, WLM will fail swverify checks. Workaround To ensure that WLM works properly on a system with PRM C.03.02 or later, upgrade WLM to A.03.02 or later. When upgrading from WLM A.03.00 or earlier, upgrade WLM prior to upgrading PRM.
