Hello Listers I realise that this subject is old, old, old but ....we have never had a requirement to move UCBs above 16M as we have been happily running with a private region of 8M and have not seen any CSA (below) issues. We are now looking at a strategy of consolidating workloads on fewer z/OS systems and hence expect to see an increase in both CSA usage and SQA as more devices are defined to each system.
I have seen the Redbook (SG24-4584 from 1995!) which gives some information, but I can't see anything from recent times. Can anyone please point me at some recent conventional wisdom, or is moving UCBs above a "non-event"?
