Control‑M uses JES services to read the job’s output. This is how Control‑M analyzes how the job finished executing. It is important to remember the following limitations:
Jobs submitted by Control‑M can be canceled by the operator. It is important, however, not to purge their outputs. Therefore JES commands $PJnnn, $CJnnn,P and similar commands must not be used.
Job output for jobs submitted by Control‑M must not be released for printing except by Control‑M. Therefore, do not activate MVS JES2 command $TO and similar commands on the job’s output. Ensure that output management products (such as CA-View, CA-DISPATCH) do not remove a job’s output from the spool until Control‑M has first analyzed the output.
If JES operator command $HJ is issued for the job, the job must be released from held status before Control‑M can read the job’s output. Otherwise, the job status is changed to EXECUTING (SYSOUT IN HOLD STATUS).
If the Control‑M monitor cannot read a job’s SYSOUT, the following message is displayed on the operator console:
CTM262Wn UNSUCCESSFUL ATTEMPTS TO READ JOB DATA BY SUBSYSTEM REQUEST. RETRY CONTINUES
Message CTM262W does not necessarily indicate a serious problem.
