Adabas, zOs and WLM
Hi, How many of you have different WLM defintions for a Day time load and a Night time load in zOs . The LPAR is running CICS, ADABAS, SHADOW ? I am trying to tell them the concept of having different WLM settings for the different parts of the day , is old fashioned ex. We have WEB applications now and there is no point in increasing the Batch priorities when the CICS's are doing nothing at night. Difficult to explain because they believe the Batch jobs will go faster at night if you UP the priorities in WLM. Warnings : Any of your responses might be distributed in our organization , so please talk slowly so that everybody will understand. Note: Opposing views/opinions are always tolerated because that is how all of us think about we do, before doing it.

Re: Adabas, zOs and WLM
With the possible exception of the number of batch initiators started (with WLM managed inits a moot point) I have been opposed to different service definitions based on shift. With WLM, it is even more unnecessary IMHO. For example, if there is no IMP=2 work running on the system, IMP=3 work will run faster just by nature.

Re: Adabas, zOs and WLM
I our environment we have A LOT of online (DB2 distributed) work that kicks off at night from a server somewhere. If we let it alone it would eat our lunch and batch processing windows would be missed. We have a night time definition that lowers the distributed work down to lower than a snakes belly. Who cares if it takes 4 hours? You are correct that it makes no sense to have a night time specification if there is no online work being done. That being said, it might just be easier and less aggravating to go along with it. Sounds like upper management has been talking to their buddies in a different environment again. Good luck.

Re: Adabas, zOs and WLM
Hi Anton, At my prior gig we had North American, mostly CST and some EST zone work and a UK workload. I supported one WLM policy. The workloads were grouped as usual, prod onlines, prod batch, test onlines, test batch, etc I had CICS, IDMS, Adabas, Complete, WAS, Domino, TSO. You get the picture. My UK workload was not as resource intensive as my North American workload. In my case I did have some higher importance workload during off hours, namely UK online production, but was able to tune the policy so that the CST/EST nightly batch cycle still completed in time for the North American morning rush. I should say that I was in EST zone and with the physical box. I won't say this was without issue(s) but for the most part, and on most days, there was no significant impact to the core business related workloads. If you have no online or higher importance workload during the nightly batch process increasing the WLM Importance is almost the same as leaving it alone, to some extent.
