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
or channels and containers
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.
