Interoperating transactionally between application servers

This topic describes some considerations and actions that you can take to interoperate transactionally between different types of application servers.

Why and when to perform this task

WebSphere Application Server is a transaction manager that supports transactional interoperation with other transaction managers through either the CORBA Object Transaction Service (OTS) protocol (for example, application servers) or, for JSR-109 compliant requests, Web Service Atomic Transaction (WS-AtomicTransaction) protocol. This is in addition to its ability to coordinate XA resource managers and to be coordinated by J2EE Connector 1.5 resource adapters.

To interoperate transactionally, using the OTS protocol, between WebSphere Application Server version 6 and versions of the WebSphere Application Server before version 5.0, you need to set the following system properties on application servers that are before version 5.0:
com.ibm.ejs.jts.jts.ControlSet.nativeOnly=false
com.ibm.ejs.jts.jts.ControlSet.interoperabilityOnly=true
For example, if you want to interoperate between application servers at WebSphere Application Server version 6 and WebSphere Application Server version 4.0.n, you need to set the system properties on the version 4.0.n application servers.
