Hi all,
Sorry if this has been done before but I couldn't see it.
I've recently had to debug looping code in an SRB routine on a zIIP. The only
information I could find was the PSWs out of the MVS trace entries for the CPU
timer interupts. Fortunatly there were enough of them to determine the exact
code path with a good degree of confidence and resolve the issue.
This got me to wondering is there any other info you can glean from a dump of a
looping SRB? For a TCB you could look for registers in the TCB/PRB/SVRB to get
a clue of where you were recently.
Is there anywhere else you can go for this sort of info for an SRB?
Ron.
