looking more closely - you are running 7.1 on AIX - all ports of which are
64-bit
so - the 'only one sbcs' and 'only one glm' tuning are not necessary.
You aren't bound to 11 segments per process limit as on 32-bit ports.

If you are running a 32-bit port of UniData on AIX - yes.
I spot 2 glm segments in your ipcstat listing.

That's what I did and what I remembered. Cool, the memory isn't so bad
after all. Do I need to worry about the multiple glm segments ?
Thanks!
