Hello Alan,
We are running all system V=V. I was re-thinking a lot of the
standard parameters that I have. I have time to review them now.
And you are right. I have not seen any major boost.
I am going to start a thread about MDC, Xstore, storage, and
large amounts of Cache on the external dasd.
Thanks for the info.
