CA 7 Coexist Release 12.0 and 12.1 on same LPAR

Products

• CA 7 Workload Automation

Issue/Introduction

On LPAR, can you have both 12.0 (for existing devt and prod support) and 12.1 (for their new project), coexist on the same LPAR?

Environment

Product: CA 7 

Resolution

You can have both CA 7 r12.0 and r12.1 coexist in the same LPAR.

CA 7 r12.1 will have it's own Datacom MUF and database.

You can use one set of libraries to be accessed by the L2OPTS (either Linklist or Steplib) to bring up the SVC and other system definitions. And choose the 12.1 libraries to be in front of the 12.0 libraries.

If it makes it easier for you can leave the existing CAS9 as is, and run a separate CAS9 batch job manually before bringing up 12.1 STCs.

Please note that if you are not IPLing you do not need to run the CAIRIM for the upgrade because it is upward compatible.  This can be done the next time you IPL.

You can code a new CA 7 instance for 12.1…..CA73.

You can add the new CA 7 instance without having to perform a GLOBAL DELETE + GLOBAL INIT. 

All you need is to run CAIRIM with only a CA 7 statement in the RIMPARM and L2OPTS input as such:

//L2OPTS DD *

CA73 ADD [options]

/*

You can build each TSO/ISPF session for both 12.0 & 12.1 releases, or run a native CA 7 VTAM session for each release.
