Too early in the morning; it has 4GB. Which IMHO, i would think is enough to 
run AIX and TSM.

Thanks for the previous suggestions posted to the list, but does anyone have 
any tools, tips, trick for reporting on memory or paging space usage? The best 
I have right now is: 'svmon -Put 10 | more'.

Again, we have spent 18 months looking at this. With multiple PMRs opened with 
IBM. We have run their 'perfpmr' script. We track paging space and many other 
stats. Finally IBM told us that memory leaks were hard to track down. We gave 
up to recently when we planned to upgraded to 5.3, hoping that the upgrade 
would fix the problem. However, my box lasted only a month at 5.3 before I 
rebooted it last Friday. The paging space is low today. But I'm sure that it 
will creap up.

Without perspective on what your TSM server is called upon to do, it's
difficult to render
a cogent recommendation.  However, in the abstract, 2 GB of memory for
a server system is
a tiny amount of memory these days in light of modern operating system
requirements and the
needs of a large application like TSM.  Many single-user workstations
have 2 GB.
