Since I don't use it often I can't remember when... z/OS 1.3 DFSMS (same version in z/OS 1.4) or maybe it was 1.5. I know it does in z/OS 1.6. But that doesn't apply to zFS anyway since it is VSAM. >The only reason why I rebuild IPL text EVERY time is to not miss any >updated or changes made to IPL text introduced by maintenance(granted, >not very often), but now I never have to think about it. I have seen and heard others say the same thing. But if you miss that ACTION hold, what others are you missing? I have to go through all of them anyway, so I don't consider that an issue. But it only takes a few seconds (plus an operator reply), so no harm. > DFDSS copies >it too. My running sysres's are 50% utilized(saves room for those ever >increasing ZFS dataset sizes).

All that duplication of HFS / ZFS on the sysres for backups does take a lot of space. If you use the recatalog method I plan on using, you won't have to do that. For HFS you can just define non-vsam and use indirect cataloging etc. I have always kept the tgt zones on the sysres (set) also when there has been space. When things get tight... that has always been the first thing to go to get me an extra 100 cyl. or so since the zones aren't required to be on the sysres. But today, 100 cyl doesn't buy much.
