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

Install patch PHKL_33052.

“wlmd -k failed,” “wlmpard -k failed,” “wlmcomd -k failed” messages

Issue

You may get one of the following messages when using -k with a WLM

daemon:

wlmd -k failed: Resource temporarily unavailable

wlmpard -k failed: Resource temporarily unavailable

wlmcomd -k failed: Resource temporarily unavailable

Workaround

When you get one of these messages, the -k most likely did succeed—but not

as quickly as expected. You can verify using the ps command and issue your

shutdown command again if needed.

Unable to get CPU allocation due to number of processes

Issue

WLM provides a workload group its allocation on a system by granting the

group its allocation on each CPU. If the group does not have at least one

process for each CPU, WLM increases the allocations for the processes to

compensate. For example, for a workload group with a single-threaded

process, 10% of four CPUs is allocated as 40% of one CPU.

Assume this same group were allocated 50% of the four CPUs. WLM would

allocate 100% of two CPUs to the workload group. However, because the

group has only the one thread, it can use only one CPU, resulting in an

allocation of 25%.

Workaround

There is no workaround. However, be aware of how your applications run so

that you do not give them resource allocations they cannot use.
