SMF statistics interval? RMF statistics interval? It's not easy to catch running SRBs. Such as the the ones SMF dispatches in every address space (think DB2 DBM1) every statistics interval to rattling the chains to collect EXCP data. (RMF Monitor II). SMFPRMxx entries for DDCONS and EMPTYEXCPSEC come to mind.

From: Phil Smith <[email protected]> To: [email protected] Date: 07/31/2013 10:05 PM Subject: Dumb WLM question Sent by: IBM Mainframe Discussion List <[email protected]> There are about a thousand questions here that we should have answers to but don't, so please bear with me here. We have a customer with a CICS transaction hang problem that happens intermittently at high load times. We've been able to verify that it's making it out of CICS, doing a PC off to our server. Things clear up eventually; we have various diagnostics in our server that look like things are ok, but we're seeing it after the fact, which of course doesn't prove much. One possibility is that WLM is throttling our server. The hangs *seem* to happen at five-minute intervals. Doing some Googling suggests that WLM does *something* on 5-minute boundaries. Does this suggest anything to anyone? Like, does WLM throttling occur on those 5-minute boundaries? Yes, I'm Easter Egging. Will hopefully be able to get some real information tomorrow when the problem is occurring, but in the meantime, some pointers would be useful. And also yes, I'm trying to grok some WLM books! Having an eye infection that's forcing me to read with one eye isn't helping...
