HP-UX Workload Manager Oracle  Database Toolkit (new for

September 2001)

HP-UX WLM provides goal-based workload management. This management enables

automatic resource allocation and application performance management through the

use of prioritized service-level objectives (SLOs). It provides this functionality by

building on HP Process Resource Manager (PRM) functionality.

WLM Oracle Database Toolkit (ODBTK) A.01.00, product number T1302AA, provides an

easy mechanism for feeding Oracle database metrics into HP-UX WLM.

ODBTK offers the following features:

• Keep response times for your transactions below a given level by setting

response-time SLOs

• Increase an instance’s available CPU when a particular user connects to the instance

• Increase an instance’s available CPU when more than

users are connected

• Increase an instance’s available CPU when a particular job is active

• Give an instance

percent of the CPU for each process in the instance (This feature

is available only with HP-UX WLM Version A.01.02 and later.)

• Give an instance

percent of the CPU for each user connection to the instance (This

feature is available only with HP-UX WLM Version A.01.02 and later.)

These features are provided by ODBTK’s:

• Ability to gather and send Oracle database metrics (elapsed walltimeand SQL

values) to HP-UX WLM for use in service-level objectives

• Ability to average extreme values in database metrics before sending them to HP-UX

WLM (This feature maintains a more smooth and predictable stream of metrics.)
