OPD - OMVS Process Data Report

z/OS Unix address spaces can consist of several processes, which in turn might run one or more threads. Each process is typically associated with a UNIX command, consumes a certain amount of CPU, and also provides state information. UNIX System Services is the brand for UNIX on z/OS. In this context, it is referred to as open MVS or OMVS.

In addition to other reports that show OMVS address spaces with their jobname and using or delay information, the OPD report can be used for problem determination. It assists the performance analyst to find answers to the following questions:

What are the delayed processes?
What command is associated with them?
What is the status of each of the processes?
Which processes are high CPU consumers?

Address spaces under OMVS control are indicated by an additional letter O in the class column of the DELAY, the PROC, and the JOB report. The performance analyst can then use cursor sensitivity to navigate to this report or alternatively invoke it directly depending on the task he is trying to accomplish.

The report provides basic performance metrics on the first screen, while additional information specifically related to server processes can be shown by activating a pop-up panel.
