JCPU


The JCPU service provides the ability to locate the address spaces that are the highest users of CP, zIIP, and zAAP processors.

Related topic

The JCPU service reports on the distribution of CP, zIIP, and zAAP processor utilization during the sample period. The information may be sorted by any column. When sorted by CP, zIIP, or ZAAP the column is sorted in descending sequence and the display terminates when the last non-zero value has been displayed in that column. The user may specify a sample period from 1-60 seconds. The default is five seconds.

The unused processor time during the interval is not measured. Therefore, the total utilization will always be 100% for the sorted column (subject to rounding errors).

Important

The JCPU service includes a job's ASSBPHTM field, which represents the CPU time consumed by preemptible SRBs running in the job. For information about the CPU service that uses a job's ASSBPHTM field, see CPU.

Parameter

Description

n

A numeric value is assumed to be the sample interval in seconds and must be 1-60. If a value greater than 60 is specified a warning message is issued and the duration is set to 60.

keyword

A non-numeric value must be one of the supported keywords and is used to identify the column used to sort the data. The keywords are: ASID, CP, NAME, ZAAP, and ZIIP. The default is ZIIP.

Example 1

This example shows sample processor usage for one second and sorts the resulting data by the column containing CP utilization in descending sequence.
