Why COMMQ file grows to high usage even with few queued up messages on CA Workload Automation ESP Edition system?

Environment

CA WA ESP Edition Z/OS

Resolution

In COMMQ file, there can be data related to Report Server. When Report Server STC is not running, ESP will try to write JOB tracking data for up to one hour when ESP STC is restarted. The data can't be cleared by any command or utility.

To clear the data, you can: 1. Issue RSERVER command to stop TRACKING, so that no more Report Server data be written to COMMQ file.; 2. Reformat/define a new COMMQ to clear the data.
