A CICS waking up from no activity will often exhibit a spike in paging. Generally speaking, transient spikes are very rarely of concern. It is only when the average stats rising above zero do you need to be looking to increase main storage.
Of course, some might argue that, depending on the workload, an overall average system page in rate of a few per second means you are exploiting your main storage to the fullest: you are getting real work out of what you paid for.

In fact, our real storage is still sufficient (from paging activity report) . how comes it needs paging in? thanks and regards ---------------------------------------------------------------------- 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 NOTICE: This electronic mail message and any files transmitted with it are intended exclusively for the individual or entity to which it is addressed.
