CPU Utilization by Protect Key Report

The CPU Utilization by Protect Key Report shows CPU status by storage protection key.

The CPU Utilization by Protect Key Report is produced by using the PROTKEY Analyzer control statement. The data is obtained by using the CPU Extractor control statement.

There are three sections in the CPU Utilization by Protect Key Report:

  • Sub System
    This section gives information about protect keys 0 through 7.
  • V = V
    This section shows all jobs running under key 8 for V=V.
  • V = R or Special V = V
    This section shows all protect keys that had either nonpageable jobs that were running under them or pageable jobs that were not in key 8. Keys 9 through F can appear in this section as well.

If dashes (---) appear for a given protect key under the CPU column, no activity information was encountered during sampling. If dashes appear for all protect keys under a given CPU, that CPU does not exist. For purposes of this report, you must specify the ID of the CPU to be examined.

The following figure shows an example of the CPU Utilization by Protect Key Report.
