The CTGMASTER_RRMNAME parameter is no longer supported
This release of the CICS® Transaction Gateway does not contain a ctgmaster component. This component is no longer required for the Gateway daemon to support TCP/IP load balancing with XA. The CTGMASTER_RRMNAME parameter is not valid.
The CICS Transaction Gateway fails to start.
Remove the CTGMASTER_RRMNAME variable from the configuration file. You will be required to configure the APPLIDQUALIFIER and APPLID parameters to enable XA support. Refer to the CICS Transaction Gateway Information Center for the necessary steps to migrate to the current release when using XA support with Gateway groups.
