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.
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 1 shows the JCA objects corresponding to the CICS terms.
| CICS term | JCA object: property |
