|| I guess i was making the point that the pool was fixed, and too large.
and that CSFT wasn't helping things by forcing additional pool mgmt
As to what defines a large shared pool depends heavily on the

|| Number of apps and users, plus considerations of pinning, reuse, bindvars
versus not. I haven't ever seen the need ( up to, say, about 500 concurrent, busy
thin-client users, multiple apps ) to have a pool larger than 150MB. On your
machine with the 400MB pool, how many users did you have, and was it something like an AR/AP or GL setup?

|| This is interesting. Have you experimented at all with monitoring space
swapping between namespaces in the lib cache, and did you see anything there? Thinking about this will be useful, i believe....thanks for the thoughts Andrew Received on Tue Apr 20 1999 - 01:07:52 CDT
