Preventing Job Logs from Being Produced

To prevent a job log from being produced at the completion of a batch job, specify *NOLIST for the message level text of the LOG parameter
on the Batch Job (BCHJOB), Submit Job (SBMJOB), Change Job (CHGJOB), Create Job Description (CRTJOBD), or Change Job Description (CHGJOBD)
commands. If *NOLIST is specified for the message text value of the LOG parameter, the job log is not produced at the end of a job unless
the job end code is 20 or greater. If the job end code is 20 or greater, the job log is produced.

SBMJOB LOG(4 0 *NOLIST)
CHGJOB LOG(4 0 *NOLIST)
CRTJOBD JOBD(QGPL/JOBD) LOG(4 00 *NOLIST)
CHGJOBD JOBD(QGPL/JOBD) LOG(4 00 *NOLIST)

For an interactive job, the value specified for the LOG parameter on the SIGNOFF command takes precedence over the LOG parameter value specified
for the job.
