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

To Get the Figure of ASP% 2 hours ago, is not possible, until some CL process is running and sending the information to some file.
To know the current jobs status of the system, go to WRKACTJOB, move the cursor to CPU % column heading, and press F16 (Shift+F4), the list will be sorted in CPU utilization descending order, there you can check, what job is taking more CPU, and u can work with job.
To check what job was disturbing the system, (If it is ended) run command, GO PERFORM, and choose option 7, select the date you want the check for, from provided list, select the time interval u want to check for, (u can choose only the sequential time interval, not multiple at one time). press enter, then press F6, it will show the jobs active in the system during that time, at this screen u can sort the data as u want, (options r mentioned in the screen below) hope this will help.

    How can i get detials of ASP% for suppose a couple hours back. That probably isn't quite what you can find out unless you have special programming that provides it. Most likely your best choice is iSeries Navigator. Drill into your connection to view Work Management-> Active Jobs. Right-click, select Customize this View-> Columns... and add the various DB columns to the view. With database data being listed, sort the list by Disk I/O Count or other DB values. If any one job appears to be excessive, investigate it more closely. The WRKACTJOB display can give similar results. However, without knowing what your environment is like, we can't know what problems you might run into. Your space might be taken up by inserts into database files, by generation of journal entries, by creation of spooled files, by clients copying stream files into IFS directories or by a few other possibilities.

    how find which job currently running is increasing the ASP ? Do what I told you in the previous comment. List the jobs and sort them by the different DB statistics to see which jobs show at the top of the lists. Investigate jobs that show high disk activity. GO PERFORM will not help you right now. You need to know what the jobs are supposed to be doing. If you don't know that, you can't find out if any one job is not working correctly. You can only look at the jobs that show the highest activities. Many jobs are probably contributing to a rise in ASP %. Most likely, one will stand out from the others. Tom

    RTVDSKINF (DB2) and RTVDIR INF (IFS) might help. Keep in mind that these are long running commands, typically more than one hour. These commands build tables. After the commands completes, use PRTDSKINF and PRTDIRINF to get the results. Prompt the commands for filter options. We recently had a run-away job but did not know which one because the system went into a restricted state. These commands helped up find the offending application by pinpointing a huge object.

    RTVDSKINF (DB2) and RTVDIR INF (IFS) might help. Those could be used after the problem occurs if individual objects grow larger. If it's a series of objects such as multiple journal receivers or QHST files or multiple joblog or other spooled files, they may not be much use. Also, they can take hours to run and may result in pushing the system past its thresholds as they collect all their data. In the meantime, any problem jobs also continue to consume space. They would definitely be more useful if they had previously been run at periodic intervals so that the change from the last run could be located. Tom
