Howdy Tim,

 We run all that here. Not sure what you're looking for but I can 
tell you how we use WLM here in conjunction with them. As you can 
imagine there's all sorts of schools of thoughts that work. Take this as 
it works here but not maybe not somewhere else.


Importance of 1, execution velocity of 40 for ADABAS, GBP

Importance of 1, execution velocity of 17 for COMPLETE, ETB ( broker )

Importance of 1, execution velocity of 8 for RPC servers

Resource group based on SU's - Day - 5k, Night - 7k for ADABAS, GBP

Resource group based on SU's - 4k COMPLETE, ETB

Resource group based on SU's - 3k

I'm surprised Lizette hasn't piped up already but I'll pass along that you 
would probably get a better response via sa...@listserv.uark.edu which is where 
the SAG clients hang out.  I've cc:'d them in this message.

Since we were DB2, Adabas (for Predict) was not a specialized WLM case for us.  
Perhaps others have done more detailed work.   We were using Transaction Goals for 
CICS especially to weed out the long-running transactions ie. OmegaMon, & Cics 
system tasks, so they didn't pollute the response times collection.  They were 
given 5-10% CPU goals but got carried along by the Transaction Goals since CICS is 
adjusted by WLM as an entire region.  I seem to recall there was some discussion in 
the SysProg WLM Guide Redbook to this effect.  [1]  I re-read the guide many times 
and found new insights [2] even after a few years had elapsed.

[1]  I created a 'medium' Goal with more relaxed response times intended for 
the lessor-preferred transactions but we never got around to making any 
distinction.
[2]  The biggest being that the goals should not be specified as 'What you want'.  Instead, they should be 
more, "when the stuff starts flying, I'd like these (acceptable) minimums, plz."  For example, 
instead of "I'd like this to get 80% CPU", you should say, "if things are bad, this could 
survive on 40% CPU.  I won't like it but we'll stay processing."  If you're not constrained, WLM will 
let you over-perform but if you artificially constrain it, it can't steal from other processes to smooth 
things out.  I especially like how WLM will temporarily boost a low-goal process that's holding 
up/enqueing/locking a higher process.  It shows up in the RMF report as below:
