CICS® Transaction Gateway processing continues. Extended logical unit of work requests fail to start.
If the return code is non-zero, contact your service organization for more information and diagnosis, or refer to the z/OS MVS Programming: Resource Recovery book, for details of the return code and any corrective action which should be taken. Common failing return codes are: 300 - CRG_RM_NAME_INVALID - The resource manager name is invalid. If the CICS TG registers as an unauthorized resource manager a .IBM.UA suffix is required. Refer to the CICS Transaction Gateway Information Center for details on which configurations the CICS TG registers as unauthorized and which characters are valid in an RM name.
