Re: PWRDWNSYS

a question I have is:
why, when you do a PWRDWNSYS, would you EVER really want cache data left behind?
I would think that the 99% choice would be to flush the cache.
When I IPL my system, it is after a ton of unrelated batch processing, and a full system save. what is in the cache will be no real help when I restart my machine for normal business operations.

This topic ended up, as it should have, focused on flushing cache. As I think about it, if ENDSBS *ALL does not completely flush the disk cache and it isn't completely flushed until a PWRDWNSYS *CNTRLD is done then every restricted state backup ever done is potentially invalid UNLESS all the save commands somehow save the information in the disk cache. Thoughts, again?
