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
the September 2010 ""IUA Connections"" with great interest as our
site experienced the problem that he describes. Chris
indicates that the numbered user exits can contribute to
TCB/SRB swapping. We use exit 28 (security pre-processing) and
I am wondering if this could account for some of the high
swapping rate that we saw.

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