Hallo,
ich denke da hilft Dir das:

Enter the GO CLEANUP command and select option 1 to make sure cleanup is scheduled. Once scheduled, you will see the QSYSSCD on WRKACTJOB running in the QCTL subsystem. If you do not see the job QSYSSCD running, issue the ENDCLNUP command followed by the STRCLNUP command. This will activate the job.
