Really, you need to get a >monitor. No, really. I fully agree about the need for a performance monitor, but that is for more advanced problems. For E-lists a simple INDICATE command will tell you if there are any, and IND Q EXP will tell you who is sitting there.
>- What are your z/VM SRM parameters? The defaults aren't good for Linux >workloads. I beg to disagree (sorry, Barton!). I have been running for years with the defaults and never had an E-list problem. If you do, my suggestion is that your system is wrongly set up. Most likely your paging subsystem is underpowered for the task at hand. >- How much real and expanded storage does your z/VM system have? That's not >enough, get more. Simply telling to get more real will kill the business case. At the prices IBM is charging zSeries will lose out. I know, I am up against guys running blade servers with 256GB apiece. They can afford to waste some at the price they are paying. I can't. >- Does it really need to be that big? You should try shrinking it. Some you can't shrink (eg. SAP engines, databases etc).
