Tom, Sorry I wasn't clear. These processes don't run simultaneously. We run 2 production LPARs and at times during our nightly batch cycle we have a process on one or the other LPARs that will consume an entire processor for a period of time - anywhere from 10 minutes to an hour or longer. Watching my SDSF-like screen or monitor, I can see that a single TCB is consuming 100% (or close thereof) of one of the engines.
