Starting multiple CICS Transaction Gateways
See the SCTGSAMP PDS library for sample JCL.
To start multiple CICS® Transaction Gateways from OMVS with console input when directed to a port that is portshared, define the jobname "OMVS" as having access to the shared port in the TCP/IP profile. If console input is not required, then start the CICS Transaction Gateways via JCL and define the JCL jobname in the TCPIP profile.
See Port is in use by another task, for information on a problem that can be caused when the CICS Transaction Gateway jobname is shorter than eight characters.
