Issue/Introduction

While implementing another product (SYSVIEW) a decision was made to store the r20 version of the IDB2COMM module in a library (along with the r20 module PTLTSRB) that is in the LNKLST of the z/OS image.  Can the r20 version of the IDB2COMM module be used to also access the r19 version of IDB2?

 

Environment

Release : 19.0

Component : CA Detector for DB2 for z/OS

Resolution

The r20 version of the IDB2COMM module is downward compatible, and can be used with previous versions (in this case r19) of IDB2.

Additional Information

Along with the IDB2COMM module, the PTLTSRB module is also downward compatible.
