desired duration for an application.

setting response-time SLOs
• Increases an instance’s available CPU when a particular user
connects to the instance
• Increases an instance’s available CPU when more than n users are
connected
• Increases an instance’s available CPU when a particular job is
active
• Gives an instance n 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.)
• Gives an instance n 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
walltime and 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.)
