I would say you have 2 challenges here. One managerial, which causes the second technical one.
Managing your system to provide appropriate service at all times may require some discussions with the non-technical folks. Productivity should not necessarily be sacrificed for the sake of lower importance Batch. No matter how many people thing compiles need to be turned around in less than 30 seconds. Once you have that agreement, fix your WLM Service Policy. TSO is Interactive (along with some USS work), and setting the proper Goals will help a lot. I prefer 2 Service Class Periods; some sites prefer 3, in order to catch the longer running work that really does belong in Batch. For a 2 Period Service Class, I would like to see 95% of the work complete in the 1st Period, with 5% in the 2ne Period. Use something like: P1- 95% < .5 seconds, Importance=2 with DUR=500 or 1000 (depends on your coefficients and how generous you want to be). P2- Velocity = 31, Importance=4 (avoid DISC, unless you have spare capacity). Run the change for about a week, then adjust your duration to hit the 95-5 recommendation. Depending on if you want complaints to start or you want to create a wide berth, start with 1000 and move down to 750 to 500, if you are way over-achieving the rule. Or start at 500, listen to complaints, and gently increase the duration. Please be sure that there is very little Batch (or any other over-aggressive work) that is being managed above the 1st Period work. ============================================================================ ===== Sorry for a newbie to jump in here... But I have a question: why IBM doesn't increase the clock of mainframe CPU? There is no need or there are some technical problems? I'm now working at one customer's site and every day's afternoon is a terrible time for all developers working on their development system: we just cannot use TSO/ISPF! You must wait 4 or 5 seconds for a response and sometimes you just hang there. The cause is that most teams will do their batch tests at that time thus eating all of CPU cycles. I guess they might need a more powerful CPU? (This situation has last for three months since I came here) -- Best Regards, Johnny Luo ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
