Look at any system trace in one of your dumps for PIC 011s and you can see how the flow goes for a page fault program interrupt...if you want more detail the other responders have pointed you to the right place.

Hadaway Senior Systems Programmer/Analyst University of California San Diego Medical Center (619) 543-2270 [email protected] -----Original Message----- From: IBM Mainframe Discussion List on behalf of David Stephens Sent: Fri 10/9/2009 8:39 PM To: [email protected] Subject: Page Faults and Interrupts I've always thought that a page fault in any operating system, including z/OS, would generate an interrupt. The task requiring the missing page would be put aside whilst RSM did the required I/O to the page datasets (unless the page was already in memory - in expanded storage, or a stolen page). However, I haven't been able to find any mention of this interrupt (Principles of Operation mentions the six interrupt types), and how it works. Can anyone clear this up? Does a page fault generate an interrupt like a program exception? If so, what sort? If not, what happens? Thanks for your help.
