HP-UX Workload Manager A.03.01 Release Notes for HP-UX 11i v1 and HP-UX 11i v2

HP-UX Workload Manager Release Notes

Known problems and workarounds

Collectors abort when updated while running

Issue

If you update (overwrite) a data collector executable (be it a binary or a

script) while it is providing data to WLM, the collector may abort.

Workaround

There are two workarounds to this issue:

• Update the data collector in place

1. Stop WLM (wlmd -k)

2. Update the data collector

3. Re-start WLM (wlmd -a configuration_file)

• Replace the data collector

1. Move the current data collector aside

2. Install the new data collector in place of the collector you just moved

aside

3. Re-start WLM (wlmd -a configuration_file)

GlancePlus/OpenView Performance Agent and processor sets

Issue

On systems with multiple processor sets configured, GlancePlus may have

incorrect data for the PRM_SYS group (ID 0). On these systems, GlancePlus

will incorrectly include processes that are outside of the default processor

set as belonging to the PRM_SYS group (ID 0).

As a result, WLM’s glance_prm data collection script cannot be used to

track application (APP or APP_PRM) metrics for the PRM_SYS group or any

PRM group defined based on a PSET.

Only GlancePlus is affected by this issue—WLM properly identifies

workload groups (PRM groups and their PRM IDs).

Workaround

For HP-UX 11i v1 (B.11.11), using GlancePlus C.03.55 or later and

installing patch PHKL_28052 addresses this issue.

For HP-UX 11i v2 (B.11.23), this issue is fixed in GlancePlus C.03.58.05.
