The continued case for why TSM and AIX should be jointly administered....
Our AIX admins are claiming that TSM has a memory leak. We are claiming we need adequate paging space (ie. 6 GB of memory, not 100 MB of paging space) and that VMTUNE maxperm needs to be roughly equivalent to numperm (along with a slew of other variables that makes sense).
Anyone know of a memory leak on TSM 5.1.6.3 on AIX? If so- I'd be happy to find that out as the root cause of AIX dropping telnet requests due to low memory conditions.
Thanks,

I haven't seen any memory leaks, but in regards to AIX vmtune + TSM, search the list archives. IMHO, maxperm should be set very low, since the AIX buffer cache is going to be next to useless. I'd go 8%, or less.
We have an AIX system where I'm about to set "vmtune -p 1 -P 2 -h 1" in order to get vmstat "sr" lower, and stop wasting kernel CPU. It's a big Oracle box with 8 GB RAM, but has similar "heaps of I/O" characteristics as TSM.
