Ken Wallis wrote (different thread): With decent tuning you should be able to find a reasonable compromise between making lots of memory available for big jobs without lumbering little jobs with a huge footprint. Even on AIX now there are some extended shared memory facilities which allow you to have more segments instead of just making them all huge! I can't remember the exact details but EXTSHM rings a bell. __________ My comment: Due to the way UniData uses shared memory (eg - all udt processes have to attach the smm - ctl (global control table) segment) and the way AIX implemented extended shared memory (memory mapped files), there can be performance issues (contention for access to a single segment). This was identified at a site running 12-1500 users, but I imagine it would raise its ugly head at smaller sites as well. In spite of suggesting this when I originally wrote a white paper on UniData and AIX, we no longer recommend implementing it.
