Thanks. We'll let you know when a new response is added.

As a start, use GO CLEANUP. Also try RCLSPLSTG.

Good luck.

    Save your QUTQ's to tape with their spooled files. Deleted Old Spooled files from the system. Delete job logs.

    For background, run DSPJOBTBL. Then review the <help> text for Initial, Additional and Available job structures. The <help> text describes the relationships between those values and different system values that you might want to adjust. Also, press 'F11=In-use entries' to see if 'Pending' joblogs might be a source of rising numbers of jobs. How many jobs show in your system? What OS version/release are you running? Tom

    Enter command WRKUSRJOB QSECOFR if you find the job below SRVMON0001 QSECOFR BATCH JOBLOG PENDING The job number ranges 0001 to 0076, and there can be hundreds of them in joblog pending, simply delete them with option LOGLMT(0)

    There's a good 2-part article on this on the 400 Guru website: Part one: http://www.itjungle.com/fhg/fhg092408-story03.html Part two: http://www.itjungle.com/fhg/fhg100108-story03.html Good luck!

    The two IT Jungle articles mostly cover what can cover here if we get a little more info on where the excessive jobs are coming from. There is a third article in the series -- Admin Alert: When System Job Tables Attack, Part III. And that article links to a useful IBM Redpiece -- Best Practices for Managing IBM i Jobs and Output (and a few other special tips). We can provide sample code for some cleanup work if we are told what needs to be cleaned up. E.g., a utility to clear away "pending" joblogs might be appropriate. Tom
