HP-UX Workload Manager A.02.03.01 Release Notes for HP-UX 11i V1.0 and HP-UX 11i V2.0

HP-UX Workload Manager Release Notes

Compatibility information and installation requirements

WLM configurations cannot be activated when there is less than 100

Mbytes of available memory

Issue

When you have WLM controlling memory, it gives each workload group 1%

of the memory when a configuration is activated and then adjusts the

percentage for workload groups with active SLOs based on settings in the

configuration.

However, WLM requires that the initial 1% of memory represent at least 1

Mbyte. On systems with less than 100 Mbytes of available memory, that 1%

is less than 1 Mbyte. As a result, WLM cannot activate the configuration in

this case.

Workaround

Increase the system’s memory or decrease the minimum dynamic buffer

cache using the kernel parameter dbc_min_pct.

Compatibility information and installation requirements

The following product is now available for HP9000 servers running HP-UX 11i V1.0 (B.11.11)

• 5 Mbytes of memory (Also, your system must have at least 100 Mbytes of available

memory for WLM to properly manage the workloads’ memory usage.)
