Table 4 HP-UX 11i v2 (B.11.23) patch for WLM (continued) HP-UX 11i v2 patch* Description PHKL_33604, PHKL_33605 NOTE: Install these patches at the same time. These patches help ensure each job within a FSS-based PRM group gets a more equal share of the group’s entitlement than it would under HP-UX semantics. PHCO_34599 Addresses a libc defect relating to ps, cron, login, and other such commands * These patches may have been superseded. You can use the patches listed here or their superseding patches.
Compatibility with long hostnames PRM supports long hostnames. You must install the bundle NodeHostNameXpnd and configure the feature first though. For more information, see the section “Installation procedure for B3835DA” (page 8).
4 Known problems and workarounds This section discusses problems and workarounds for HP PRM Version C.03.05. PRM does not support disk bandwidth management on VERITAS File System (VxFS) Issue PRM does not support disk bandwidth control on VxFS. The reason for this limitation is that VxFS does not support the implementation of I/O disk bandwidth that PRM relies on. The Unix File System (HFS) supported this feature, but when HP moved to VERITAS File System 4.
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. Colons in alternate names Issue You get a message similar to: Cannot parse configuration record at line 3 -- contains too many fields.
High CPU load may reduce CPU entitlements of PRM groups with few processes Issue NOTE: With Hyper-Threading disabled, each core is seen as a CPU. With Hyper-Threading enabled, each core can be seen as multiple, logical CPUs.
Workaround Be sure your applications that access the network bind only to sockets on the virtual network interface created for their respective secure compartments. For more information, see the Security Containment release notes and the HP-UX 11i Security Containment Administrator’s Guide.
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.03.04) 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.03.04 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. Upgrading or installing PRM before upgrading WLM from C.
