Reply with quote

Hi,

In a company I recently joined, I am finding some CICS TS libraries where they only have one version (used for both prod and dev) across multiple LPARs (except sandbox) with shared DASD.

They are the following:

SDFHCOB
SDFHEXCI
SDFHMAC
SDFHPARM
SDFHPL1

I am trying to determine the most appropriate time to upgrade these from CICS TS 4.1 to CICS TS 5.3 during my region upgrade phase that will be staggered.

I am assuming that since CICS TS 5.3 would be downward compatible to CICS TS 4.1 and therefore the best time would be to upgrade these libraries to CICS TS 5.3 before starting the region migrations.

Even though these are not directly used by CICS regions, they are for compiles and I want to make sure that any compiles/execution (COBOl, etc...) do not have issues regardless if a CICS region is CICS TS V4.1 or V5.3.

Does this sound like the correct approach?

Thanks,
Kyle.

In my opinion, you should NOT upgrade the libraries used in the compile/link process until AFTER the production regions have been upgraded. A newer release of CICS may provide features which are not available on the earlier release and, if developers exploit these before production is ready, you will have issues.
