WS-Transaction and mixed-version cells

You must consider WS-Transaction policy type enablement and behavior, and the WS-Transaction specification level to use, when a cell contains servers at different versions; for example, WebSphere® Application Server Version 7.0 or later and WebSphere Application Server Version 6.1 Feature Pack for Web Services.

WS-Transaction policy type enablement

For a Version 6.1 Feature Pack for Web Services server, you can enable the WS-Transaction policy type by including it in a policy set, but you cannot configure it. For a Version 7.0 or later server, you can both enable and configure the WS-Transaction policy type. Configuration information is written to the WS-Transaction policy type file.

In a cell with both Version 6.1 Feature Pack for Web Services and Version 7.0 or later servers, the following behavior occurs:
  • If a Version 6.1 Feature Pack for Web Services server reads a WS-Transaction policy type file that is generated by a Version 7.0 or later server, the server enables the WS-Transaction policy type, but ignores any configuration information in the file.
  • If a Version 7.0 or later server reads a WS-Transaction policy type that is generated by a Version 6.1 Feature Pack for Web Services server, the server enables the WS-Transaction policy type by using a value of Supports for the WS-AtomicTransaction and WS-BusinessActivity protocols. This value is equivalent to the existing behavior of a Version 6.1 Feature Pack for Web Services server.

WS-Transaction specification level

WebSphere Application Server supports the WS-Transaction 1.0, WS-Transaction 1.1 and WS-Transaction 1.2 specifications. In practice, version 1.2 of the WS-Transaction standard is functionally equivalent to version 1.1, so within WebSphere Application Server, wherever WS-Transaction 1.1 is supported, WS-Transaction 1.2 is also.

A WebSphere Application Server Version 6.x server supports WS-Transaction 1.0. A Version 7.0 or later server supports WS-Transaction 1.0, 1.1 and 1.2.

No special restrictions apply to a cell with both Version 6.x and Version 7.0 or later servers.
