Using multiple releases of CICS TG

You can run multiple versions of the Gateway in the same LPAR. To enable this when using XA support, the CTGRRMS services must be running, and must be at the level of the latest release of CICS® Transaction Gateway installed on the LPAR.

You must use ctgasi or a Gateway from the latest release to start the CTGRRMS services before you start any of the Gateways from the earlier releases. The CTGRRMS service task stays active for the duration of the z/OS® image. Therefore, starting or refreshing the services must be done when the new release of the Gateway is installed, or following a re-IPL of the LPAR.
Check that the LLA list contains the latest level of the SCTGLINK data set by using this command:
DISPLAY LLA
and see Refreshing CTGRRMS services if you need to refresh CTGRRMS services.

If you need to re-IPL an LPAR, perform the procedure described in LPAR IPLs in an XA environment.
