TCP/IP Requirements

The requirements for TCP/IP communication to the CICS region are:

Note: The default transaction is CIEP. This can be changed. You may want to set STATUS(OPEN) so that the transaction is started when installed. The default port is 1435. You can change this using the PORT parameter.

For the transaction to run, the TCPIPSERVICE must be installed and started. This can be accomplished automatically (by ensuring that the TCPIPSERVICE is defined in a group that is in a CICS start up list) or manually from CEDA.
