SVCCPU Parameter

Specifies the amount of CPU time used every time the z/OS directory search routine (SVC 18) is invoked.

Format

The SVCCPU parameter has the following syntax:

SVCCPU=CPU time

The SVCCPU parameter requires the following value:

CPU time

The number of CPU microseconds per SVC 18 execution. CA PMO uses this value to calculate CPU time savings.

The default value of 16 microseconds is for an IBM 9672-R66 processor. To find the appropriate time for another configuration, use the following formula:

time = 16 x (5036.2 / CPU service units per sec)

You can find CPU service units/sec (SU/SEC) for IBM processors on the IBM web site.

Default: SVCCPU=16 (for an IBM 9672-R66 processor)
