I check disk space regularly using DSPSYSSTS there are other commands with similar infoMy understanding is that if you get above 80% disk space consumption you got problems, while above 90% it is time to shut down the system until more hard drive can be added, because for the system to work right, it needs some work space.
If you check disk utilization from time to time, and it has been healthy, then suddenly crazy, I would suspect
* a runaway job that is creating infinitely large spool file entries * a runaway job that is creating infinitely large physical file.Typically for me, a runaway job is something that got into some kind of loop, so if I am able to get at spool and see which one is absurd size. I would expect that on a development box, you may be at greater risk of some software having a bug that causes an infinite loop.
Sometimes when doing a conversion, or adding new products, we can miscalculate what some application will need, disk space wise. It may be smart to uninstall the last thing that got added.
An IPL can stop the runaway job, and recover perhaps 1-2% of disk space, but it cannot erase whatever garbage was created that ate all the disk space.
DSPJOBTBL will tell you how much disk space is being eaten to keep track of jobs that generated reports that are on spool ... reports that you can delete, then recover that disk space, also recovers disk space used to keep track of the jobs that generated those reports.
Check GO CLEANUP for how long you keeping various system job logs.On our system, we have RTVDSKINF setup to regenerate the statistics at end calendar month, so we have recent statistics available. Be careful running PRTDSKINF to avoid massive door stop report ... start by selecting only those objects libraries etc. larger than some arbitrary thresh hold like 1,000 k, to see what is the truely big stuff on the system, then ratchet down the cut-off.
When implementing new applications, something perhaps ought to be run more often to see what kind of drain they putting on system resources.
Hello All, Out of nowhere, my disk utilization is 99% (total 500gb). I can go disktasks, but i doubt the job will ever finish. The system is development, hence i can re-ipl anything. Please advise what i can do, or is there any ways to locate those big files via search command?
