Hi, we have an online module using FORMATTIME for millions of times per day. It is redundant and formatted time not used in module anywhere.

Any idea if FORMATTIME removal can save CPU consumption? It is EXEC CICS call so is it costly in CPU usage?

Any pointer or input would help.

Thanks

I think, It’s not countable at large as to cause any performance issues or high CPU but if you are 101% sure it’s not needed then you can take that out.

Additionally, if you have any Monitoring tools then you can find this info right there and make decisions or talk to CICS Admin.

Common sense will (or should) tell you that any code you remove will save CPU time. IBM's API calls (EXEC CICS) are pretty efficient so no, one individual FORMATTIME call will not save much CPU time -- but removing millions of them could have a significant difference in the CICS region CPU time usage. Will removing them actually have a significant CPU savings? Only by removing them can you know for sure.
