Issue:
This question originated with CA-7 support. We have a message that can occur on any of the LPARS in the system, and no matter where it occurs, OPS/MVS is to execute the REXX that CA-7 provides for CCI support. The doc says that GSS must be set up and running for this. Apparently the REXX actually causes code to be executed in GSS. What they did not know was whether GSS must be running in only one LPAR in the sysplex or in every LPAR where OPS/MVS runs. We currently have GSS active on just one LPAR but are not using it with OPS/MVS.
Resolution:
GSS needs to execute on each LPAR where it would be used.
