I'm running into issues with paging space utilization on my AIX based TSM system.
Host OS AIX 5.2
TSM Version 5.2.2.3
Physical Memory 12GB
Dual CPU P630
TSM Database 1 36.6GB
TSM Database 2 59.7GB
I have two TSM instances running on the same box and recently (after a reboot) I've seen the paging space utilization increase dramatically. I've gotten to the point where I have to stop one of the instances of TSM and let the system recover paging space, then restart TSM. Anyone have any tips? I do think I may have my bufpoolsize settings a little high, at 1GB for each instance. I haven't experimented with lowering these settings. My cache hit is 99% consistently.
TSM Options: See Attached File (options.txt)
AIX Memory Settings: See Attached File (memsettings.txt)
