To obtain statistical information on internal resource utilization, issue the following operator command:
F CONTROLO,USAGESTATS[=type]
In this command, type designates the type of a specific internal resource.
Valid values for type in this command are RQC, PND, and WSC. When ALL is specified as a resource type, or when the parameter is omitted, information regarding all the above resource types is displayed.
The following is a typical sequence of messages displayed when this command is issued:
CTO356I USAGESTATS
CTO15EI RQC USAGE: CURRENTLY 1%, HIGHEST 1% (000001 AND 000019 OUT OF 010000)
CTO15EI PND USAGE: CURRENTLY 0%, HIGHEST 0% (000000 AND 000000 OUT OF 000011)
CTO15EI WSC USAGE: CURRENTLY 0%, HIGHEST 10% (000000 AND 000002 OUT OF 000020)
CTO357I COMMAND ENDED SUCCESSFULLY
For more information about these messages, see the INCONTROL for z/OS Messages Manual.
Control‑O users can tune the PND and WSC by adjusting the values of the WAITPR# and WSCs# parameters in the CTOPARM member. However, the RQC cannot be tuned. Look for any PTFs that correct problems handling RQC.
