Attention IBM ------

We haven't had a good discussion on caching lately...

It was recently pointed out to me that, at least for the MVS server, the
recommendation from you (IBM) is to not use caching.  Can you explain the
shift (if there was one) to this position.

I think we are all aware of the issues of having duplicate DB entries for the
cached files, but does it really add that much?  My customers seem to like
the benefits of having quick recall on files that may already be on tape.
What are the overhead and liability issues with caching enabled?
