Roger,
I really enjoyed and appreciated your response on this issue, but you've
got me to wondering at bit. I'm running TSM 5.1.8 on Win2K with 2G
RAM. I looked at my migration times which are about 20 minutes (so
that's no problem) and then did the Q DB F=D and saw that my Cache Hit
was only 96.81. You said that if it wasn't 99% it needed help. I have
it autotuning and here are my outputs:
tsm: DATAPLUS_SERVER1>q actlog begind=-2 search='expiration'

Is there something I should do to get the cache hits up to 99% even
though I don't yet have a performance issue? I realize that my
environment is quite small but it is about to double and I'd rather be
proactive. TIA,
