Considerations for the front-end transaction

Except in the special case of the receiving transaction in SEND and RECEIVE asynchronous processing, the CICS transaction is always the front-end transaction in CICS-to-IMS DTP.

The front-end transaction is responsible for acquiring a session to the remote IMS system and initiating the remote transaction. Thereafter, the two transactions become equals. However, the front-end transaction is usually designed as the client, or driving, transaction.
