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

Use WRKACTJOB to see if there are any jjobs that would generate spool files or cause any issues. If it is causing that high an increase in ASP, it should be taking a good amount of processor %.

Once you identify the job and end it. You will have time to search for the files taking up that space. It is usually thousands of spool files or a large SAVF.

    Most important, if past disk usage hasn't been tracked, then nothing exists to compare against. The RTVDSKINF and RTVDIRINF commands are supplied with the system. They should be run on a weekly basis, or on an appropriate schedule, to gather statistics. Then when questions arise, PRTDSKINF and PRTDIRINF can be run to show where differences show up. But if the RTV* commands haven't been run in the recent past, they probably won't do much good for the problem today. So... A system ASP at 22% or even 44% is not very common. Those are both pretty low numbers. But because they are percentages and show a doubling, there is an issue. Determining what the issue is might need to start with more information. How much space is in the system ASP? How many drives? How many ASPs are there? (Are any user ASPs overflowed?) What is the status of directory shares out to your network? Who is authorized to store data in shared directories? How much "Current unprotect used" and "Maximum unprotect" is shown on your DSPSYSSTS display? How much time did it take to rise from 22% to 44%? Run WRKOUTQ to see if any outq is collecting an excessive number of spooled files. Is the system ASP percentage still rising? Run DSPUSRPRF USRPRF(*ALL) OUTPUT(*OUTFILE) OUTFILE(QTEMP/PRF) and then query the outfile to see which user profiles have large and unexpected "Storage Used" amounts. Collect some basic information and post back here. Tom
