HP-UX 11i September 2005 Release Notes

General System Administration

HP Partitioning

Chapter 5

Impact

If the PROCSETS bundle version A.01.00.00.06 is already installed on your system, it can

be superseded with this new bundle, version A.01.00.00.07. If the old version is not

installed, this new version can directly be installed. This new bundle version will help

you avoid potential problems while trying to install kernel patches PHKL_30032,

PHKL_30033, PHKL_30034, PHKL_30035, PHKL_30037 or their superseding patches.

The bundle ensures that the necessary patch to the Processor Sets product is also

installed when these patches are installed. You could see a potential patch install failure

or a run-time panic if the patch dependencies for these patches are not met correctly

when using the Processor Sets product.

Compatibility

There are no known compatibility issues.

Performance

The new kernel patches in this bundle will potentially improve the performance in HP

Process Resource Manager (PRM)

or HP-UX Workload Manager (WLM)

environments.

There will be no performance degradation as a result of installing or upgrading to this

new version.
