Jane,
I know of no such limit. I'm running a 1 GB buffer pool on my 4 GB TSM
AIX server with no issues. The only thing to watch is that the buffer
pool is considered "process" memory by AIX. So the default MaxPerm% of
80% means that AIX allows process to have priority on 1 GB with the other
3 GB given preference for files. Because in my case, process memory is
25% + whatever AIX and TSM themselves use, quite a lot of memory would be
paged out to disk. So you have to adjust MaxPerm% down to allow AIX and
TSM to have enough process memory to avoid that paging activity. If you
understand what's going on that should be a one-time operation.
Good luck.
