This topic describes the prerequisites for using the IMS resource
adapter as well as the supported software configurations.
Rational Application Developer with the optional J2EE Connector Architecture
(J2C) feature includes two versions of the IMS resource adapter:
- IMS Connector for Java Version 9.1.0.2
This version of the IMS resource
adapter is based on Version 1.5 of the J2EE Connector Architecture (JCA 1.5).
IMS Connector for Java Version 9.1.0.2 is not included in WebSphere Studio
Application Developer Integration Edition. Because IMS Connector for Java
Version 9.1.0.2 is a JCA 1.5 resource adapter, it will only run in a JCA 1.5
application server or WebSphere Application Server Version 6.0 (or above)
for distributed and z/OS platforms.
In the future, enhancements to IMS
Connector for Java will be made to the JCA 1.5 version only.
- IMS Connector for Java Version 9.1.0.1.1
This version of the IMS resource
adapter is based on Version 1.0 of the J2EE Connector Architecture (JCA 1.0).
This version of IMS Connector for Java runs with WebSphere Application Server
Version 5.0.2 and above for distributed and z/OS platforms.
An IFix to WebSphere Studio Application Developer Integration Edition Version
5.1.1 also contains two versions of the IMS resource adapter:
- IMS Connector for Java Version 2.2.3
This version of the IMS resource
adapter is based on Version 1.0 of the J2EE Connector Architecture (JCA 1.0).
This version of IMS Connector for Java runs with WebSphere Application Server
Version 5.0.2 and above for distributed and z/OS platforms.
- IMS Connector for Java Version 9.1.0.1.1
This version of the IMS resource
adapter is based on Version 1.0 of the J2EE Connector Architecture (JCA 1.0).
It is functionally equivalent to IMS Connector for Java Version 2.2.3. This
version of IMS Connector for Java runs with WebSphere Application Server Version
5.0.2 and above for distributed and z/OS platforms.
The following new function is included in Versions 2.2.3, 9.1.0.1.1, and
9.1.0.2 of the IMS resource adapter:
- The control of whether undelivered output for commit mode 0 interactions
on shareable persistent socket connections is queued or discarded. This function
is controlled by the purgeAsyncOutput property.
- The option to provide the name of a destination for undelivered output
for commit mode 0 interactions on shareable persistent socket connections.
This function is controlled by the reRoute flag and reRouteName properties.
- Enhanced control of the retrieval of undelivered output with the introduction
of two new interaction verbs: SYNC_RECEIVE_ASYNCOUTPUT_SINGLE_WAIT and SYNC_RECEIVE_ASYNCOUTPUT_SINGLE_NOWAIT.
- Support for use of RACF keyrings as SSL keystores and truststores.
In addition, IMS Connector for Java Version 9.1.0.2 adds the following
JCA 1.5 performance enhancements:
- Lazy Transaction Enlistment Optimization
- Lazy Connection Association Optimization
Note: IMS Connector for Java Version 9.1.0.2 does not provide the following
JCA 1.5 implementations:
- Inbound messaging, transaction, and EJB invocation processing
- Implementation of the Work Management contract
- Kerberos support
IMS Connector for Java supported configurations
