HP-UX 11i September 2001 Release Notes

HP-UX 11i Operating Environment Applications

HP-UX 11i Mission Critical Operating Environment (new at 11i original release)

Chapter 4

HP-UX WLM uses a conﬁguration ﬁle specifying workloads and their prioritized

service-level objectives (SLOs). HP-UX WLM automatically allocates CPU resources to

the workloads based on priorities and current performance.

NOTE Process Resource Manager and HP-UX Workload Manager both make use of the PRM

API. Consequently, only one of these products should be used at a time. (See also

“Process Resource Manager (PRM) (updated for September 2001)” on page 73.)

Version A.01.02

updated for

September 2001:

For Version A.01.02, new features include the following:

• Example conﬁguration ﬁles

• Ability to grant a certain amount of CPU per metric

• Integration with Oracle databases

• Integration with iCOD (instant Capacity On Demand)

• Integration with SCM (Servicecontrol Manager)

Version A.01.00.02

included in the

original HP-UX 11i:

Besides resource shares, HP-UX WLM’s bundling with PRM provides:

• An SNMP agent for accessing PRM data

• Display of resource percentages to two decimal places (was formerly integer

precision)

• Expanded ﬁeld length for PRM group names in PRM’s monitoring utilities

(30-character ﬁeld was formerly 14-character ﬁeld)

• In-kernel memory management

This version of HP-UX WLM does not take advantage of PRM’s hierarchical groups.

Installation Requirements

HP-UX WLM requires 9MB of disk space and 5MB of memory.

Compatibility Issues

HP-UX WLM can be used with any 11.x version of GlancePlus. However, GlancePlus

should be used only for monitoring, and not for changing, PRM entitlements.
