We just had an incident on a Production system where a repeating CICS transaction abend was causing our automation to trigger many iterations of a REXX program that runs in an OSF server. We have throttling code in effect, but need to deploy it more strategically to mitigate this kind of issue. Doing that will be our most immediate response.
Our Performance people were seeing OPSOSF using an unusually large amount of CPU. We don't currently use pre-compiled REXX.
That is certainly an option, but from experience I know it causes some additional complications.
We need to figure out what else to look at to improve this processing... Obviously, an approach would be to rewrite the REXX code to make it more efficient.
Is there another recommended approach we're not thinking of ?
