Caveat: list digestion leads to delayed responses... I'm surprised Lizette hasn't piped up already but I'll pass along that you would probably get a better response via [email protected] 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.
