WLM on aix 5.2?

kat115,
WLM is installed with the OS so there are not any additional filesets to install. The 3 day course is worthwhile if you are going to be looking at implementing this on a large number of servers.
The smitty fastpath is smitty wlm. All files for WLM reside in /etc/wlm but you can manage it all via smit.
The basic premise is that there are 10 tiers 0-9 and, this determines process priorities i.e. 0 being the highest. Classes use a rules file to determine which processes drop into which class, this is done via UID, GID, PID, application binary path and via tags. The class is then managed by limits or shares. I could waffle on about this all day but the redbook on WLM will take you through the basics.
The key is keep it simple, I try to only manage CPU, not memory or I/O. The simplier the better.
Best of luck.
