My own cent to this discussion: A millennium ago (before year 2000) I ear that DEDICATE dasd have better performance, maybe due no need to translate CCW. But, I change all my definitions when DEVNO was introduced: gain in flexibility, enabling dasd sharing for full packs without need to any Attach (when not in use, dasd remains FREE, isolated from CMS). And no performance problems. My question: nowadays, the performance still is a factor to use DEDICATE versus MDISK DEVNO? Thanks a lot, ______________________________________________ Clovis

(So, the question that I'm really asking is, 'What can't you do with full-pack minidisks that you CAN do with DEDICATED DASD?) Feel free to say, 'None of your business!' if you wish!
