It's not the possible problem of the real storage occupancy (conceivably in the future driving paging or some other problem) that should be the reason for investigation. Instead, it should be whether there is an application problem (such as a virtual storage leak). If you feel comfor

Let me ask an obvious question has the monitoring program been checked to ensure that it isn't collecting the data or storing it improperly (thereby accumulating data)? Many performance monitors will allow you to see the data that is contained in the allocated storage, so if you are seeing an

Virtual storage used by the task won't increase unless new GETMAIN is issued. After initial GETMAIN the working set will increase as the task begins to access more pages without FREEMAIN. These days, as real storage is usually not a problem, it's possible that those pages will reside in central s

Hi, We use a rexx program invoking ISFAFD to monitor the BATCH JOB, it is a long term running address space. The name is JCSOL, but we found the REAL STORAGE occupied by JCSOL is increased, almost 6000 frames per day. Can someone provide any train of thought to investigate this problem? TIA.
