Hi to all, I do a lot of performancetuning for my clients. I use the IBM-supplied values in the WorkManagementGuide for the activitylevel-factor. This way I determine the storage per activity-levelslot, e.g. 240MB poolsize with actlvlfactor of 4MB means an activitylevel of 60 (=240MB/4). After the initial tuning I always check how much storage the jobs actually take because this can be completely different from the IBM-values. Now let's suppose that the average job uses only 2MB in real life on this particular AS/400. I then increase the activitylevel of the pool so it will use the poolmemory more efficiently. O.K. here is the question : To be able to determine the total size of jobs in the pool I need to look at each job separately, use option 3 on WRKJOB to see the actual used amount of memory and add them all up. This will give me an estimate of how much memory is used in the pool. Needless to say that this is a very tedious job. Is there anybody out there who has found a faster way of checking the used memory per pool ? Thanks in advance, Rob.
