Measuring JCC performance

You can measure JCC performance by:

Using the EQQUX005 exit. Specific call indicators tell you when the exit has been called to start process a new job and when there is no more output to check for a job. Good performance in your exit is vital because it is called for every SYSOUT line unless you tell HCL Workload Automation for Z to stop calling it.
Observe the output queue using SDSF. The job is highlighted on the queue while it is being checked.

Performance in the JCC is influenced primarily by JES performance and also by the size of the job logs.
