Re:question about numbered user exits

Discussion created by ca.portal.admin on Oct 18, 2010
I am reading Chris Hoelscher's article on z/IIP exploitation in=20
the September 2010 ""IUA Connections"" with great interest as our=20
site experienced the problem that he describes. Chris=20
indicates that the numbered user exits can contribute to=20
TCB/SRB swapping. We use exit 28 (security pre-processing) and=20
I am wondering if this could account for some of the high=20
swapping rate that we saw.

Here is my question: Is there any way to determine how many=20
times a numbered user exit is actually being executed?

"I can definitely see the advantages of defining the exit as a program, but wouldn't that affect your performance?
