The ECI resource adapters

The ECI resource adapters provide a high level CCI interface to the ECI that can be used to link to CICS® server programs and pass data in COMMAREAs Start of changeor channels and containersEnd of change without having to issue ECI requests. The resource adapters can be deployed into a J2EE application server to allow J2EE enterprise applications to access CICS. When the JCA is used, connection pooling, security, and transaction context are managed by the J2EE application server instead of the application.

Two resource adapters are supplied:
CICS Transaction Gateway on z/OS®
Adapter cicseciXA.rar supports both XA and local transactions.
CICS Transaction Gateway on z/OS and multiplatforms
Adapter cicseci.rar supports the LocalTransaction interface, and global transactions in local mode under WebSphere®.
The cicseciXA.rar resource adapter should be used for two-phase commit functionality with IPIC. For one-phase commit functionality the cicseciXA.rar resource adapter can be used, however performance might be improved by using cicseci.rar resource adapter.
See Transaction management for details of the transaction management models that each resource adapter supports.
