HP-UX Workload Manager, HP Global Workload
Manager, and HP Process Resource Manager
The HP products HP-UX WLM, HP Global Workload Manager (gWLM), and HP Process Resource
Manager (PRM) should not be used to manage the same system at the same time. Using these
products to control resources at the same time can cause inconsistent behavior and undesirable
performance. However, you can use WLM and PRM at the same time if the PRM configuration uses
FSS groups only (no pSet-based groups) and the WLM configuration is strictly host-based. (A strictly
host-based configuration does not include a prm structure; it is designed exclusively for moving cores
across partitions or for activating TiCAP or PPU cores.) You might want to use both products on the
same system to take advantage of certain features of PRM that are not included with the latest release
of WLM, such as PRM’s CPUCAPOFF mode, enabled with the prmconfig –M CPUCAPOFF
command. (In this mode, a PRM group’s upper bound for CPU resource consumption is determined by
the CAP value, available on HP-UX 11i v3 (B.11.31) or later. For more information, see the HP
Process Resource Manager User’s Guide or prmconfig(1M).)
Note
As of WLM A.03.01, PRM is no longer included with the WLM bundle. If
PRM C.03.00 or later is already on the machine on which you must install
or upgrade WLM, you can continue to manage FSS and pSet-based
workload groups (just as if PRM had been installed with WLM). If you are
installing WLM for the first time on a machine, you can use a strictly host-
based configuration (no FSS or pSet workload groups). However, to
manage FSS and pSet-based workload groups, you must install PRM
(C.03.00 or later) separately.
