Using the JCA local ECI resource adapter

The JCA local ECI resource adapter is provided with CICS® TS and invokes local CICS programs. This is an optimized path to migrate applications using the CICS Transaction Gateway ECI resource adapter into CICS Liberty. This section applies to integrated mode Liberty only.

The JCA local ECI resource adapter is used to connect to CICS programs, passing data in either COMMAREAs or channels and containers. The resource adapter is provided by the CICS Liberty feature.

Note: The JCA local ECI resource adapter and the CICS Transaction Gateway ECI resource adapter cannot be used in the same Liberty JVM server.

Table one shows the JCA objects corresponding to the CICS terms.
