The APPLID and APPLIDQUALIFIER parameters must be specified when XA support is enabled
The Gateway daemon uses the APPLID and APPLIDQUALIFIER to create a resource manager name to register with the Remote Recovery Services (RRS). This is required for XA support.
This message is logged. The Gateway daemon does not start.
Configure the APPLID and APPLIDQUALIFIER parameters and restart the Gateway daemon. Refer to the CICS® Transaction Gateway Information Center for details on configuring XA support.
