Using the CICS ECI system layer
CICS External Call Interface (ECI) is a transaction system that requires a record for each request. In the CICS ECI communication protocol, there are two parts that work together to implement a CICS transaction:
• The CICS Program represents a CICS ECI transaction to a CICS server. Its attributes, actions, and events enable the VA Smalltalk application to make a transactional request to a CICS server and monitor its status.
• The CICS Logical Unit of Work part allows the user to logically couple one or more CICS ECI transactions together and commit them (if successful) or roll them back (if unsuccessful). The user has control over which transactions are coupled and when (and whether) they should be committed or backed out.
