Max, Do you have any resource groups defined? This is the WLM tool to limit processor capacity for a group of work. It is discussed in Chapter 7 of the MVS Planning: Workload Management book.
The more work you can throw into a service class with an associated resource group, the less likely your system comes to hitting your cap. Essentially, you trade an overall slowdown for a chosen slowdown. Of course, as always, "it depends" on the mix of work. HTH, Greg Shirey Ben E.

We haven't a SLA (at least until now) as regard response time, we have a SLA only for being up and running. We aren't running always at 4-hour cap, we exceeeds it for many hours. And FYI I guess their job as they do for mine. I give them precise answer, I'm still waiting theirs. I worked hard with WLM and system tuning in the past for this reason I wonder if the system is OK. Anyway I asked for papers, not your opinion if they're doing a good job. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
