Configuring CICS server connections

The connections that CICS Transaction Gateway uses when forwarding client requests to CICS must be configured for the supported protocol.

EXCI and IPIC are the communications interfaces for CICS® Transaction Gateway for z/OS®. If you are using IPIC exclusively, you do not need to configure EXCI. Use the CTG_EXCI_INIT environment variable to specify that EXCI is not loaded. For more information on this variable, see Environment variables: local and remote mode.
