True. But we were a "small shop" with a "small shop" mentality. We only recently started getting more of a "large shop" mentality (i.e. you don't get something done by calling a friend and just asking for something, you formally request it). But I have a winner. One jobname came up with over 25 million RACF records. Likewise a particular day came up with over 25 million RACF records. And it __appears__ that the job, run on that same day, is still on the JES2 SPOOL. Of course, I must verify this futher. But, off hand, I don't yet see exactly what has happened. But the job is a "code and go" in CA-Easytrieve Plus, which I don't really know much about. More analysis needed. But I'll bet that it is multiple OPENs of an input file (maybe one per record read?). -- John McKown Senior Systems Programmer HealthMarkets Keeping the Promise of Affordable Coverage Administrative Services Group Information Technology This message (including any attachments) contains confidential information intended for a specific individual and purpose, and its content is protected by law.
