1 Announcement HP Process Resource Manager (PRM) Version C.03.05 supports: • • • HP-UX 11i v1 (B.11.11) operating system on HP 9000 servers HP-UX 11i v 2 (B.11.23) operating system running on either HP 9000 servers or HP Integrity servers HP-UX 11i v3 (B.11.31) 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.
2 What’s new in this version PRM Version C.03.05 includes the following new features: • Placement of processes in PRM groups based on real user IDs. The prmconfig -M option now offers two modes for enabling and disabling process placement based on real user ID: REALUIDON and REALUIDOFF. For more information, see prmconfig(1). • Support for IPv6.
3 Compatibility information and installation requirements The following HP PRM products are now available for HP 9000 servers running HP-UX 11i v1 (B.11.11). They are also available for HP 9000 servers or HP Integrity servers running HP-UX 11i v2 (B.11.23) from September 2004 or later or HP-UX 11i v3 (B.11.31): • • HP PRM Version C.03.05 (B3835DA) HP PRMSIMTools Version C.03.05 (PRMSIMTools) Disk and memory requirements PRM system requirements are given in the following table, based on the PRM bundle.
Installation procedure for B3835DA Install the full PRM product, B3835DA, on systems where you want PRM to control resource allocations. To install the software: NOTE: If the PRM-Sw-Krn.PRM-KRN fileset is not installed or it is installed but its revision is older than the current revision (C.01.04), the current revision will be installed, causing a reboot. 1. Shut down any versions of PRM, WLM, and GlancePlus that are already installed.
9. Restart WLM if it was running before the PRM upgrade/installation: # /opt/wlm/bin/wlmd -A 10. Restart MeasureWare if it was running before the PRM upgrade/installation: # /sbin/init.d/mwa start PRM is installed in /opt/prm/. PRM manpages are also installed in /opt/prm/. NOTE: If you have made any modifications to your /etc/rc.config.d/prm file and the corresponding file being shipped with the PRM being installed has changed, the file /var/adm/sw/swagent.log will note a conflict.

NOTE: When you have PRM groups based on PSETs, disable PRM to perform any of the following operations: • Modify the PSETs manually using the psrset command • Adjust core (CPU) counts in virtual partitions using the vparmodify command • Adjust Instant Capacity (iCAP), Temporary Instant Capacity (TiCAP), or Pay Per Use resources using the icapmodify or ppuconfig commands • Perform online cell operations, using parolrad or any other interface, while PRM is managing the system (For more information, see the WAR
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.
connections or use the socket to send or receive data, it does prevent other processes from binding to that socket. 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.
3. Stop prmagt: # /opt/prm/bin/prmagt -stop 4. Reset PRM: # prmconfig -r 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.
