Memory pool trivia

["Haase, Justin C." <justin.haase@xxxxxxxxxxxx>]

Ok folks - I'm looking for the answer to a question (below), but I'm not
finding a definitive result anywhere and would like some feedback on it.

When looking at a WRKSYSSTS screen and looking at a memory pool, let's
use this as an example:

Sys      Pool   Reserved    Max  ----DB-----  --Non-DB---  Act-   Wait-
Act- 
Pool    Size M   Size M     Act  Fault Pages  Fault Pages  Wait   Inel
Inel 
  3     267.17       .00     90     .0    .0     .5    .6   23.5     .0
.0

The pool size is the amount of memory currently assigned, and the Max
Act is the maximum number of threads which can run at any one moment in
that pool.  If more than 90 threads are trying, you'll get WAIT->INEL
and ACT->INEL with the active to ineligible being the worst of the two -
both are bad, but active to ineligible is worse.  Correct so far?

**My question is:  Does the system deal with the pool in such a way that
there are (in this example) 2.968555 MB of memory available to each
thread, no matter how many are running (pool size / max act), or if
there's only one thread active, will it allocate all 267.17 MB of memory
to it?

Please let me know if I'm not explaining that correctly - it's more of a
personal knowledge type question more than anything, but it's good to
know.  Thanks in advance!
