Enabling secure conversation in a mixed cluster environment

When Web Services Security applications using secure conversation run in a mixed cluster environment, an interoperability property must be set for the WAS v8.5 nodes.

A mixed cluster environment consists of nodes running WAS v6.1 Feature Pack for Web Services, and nodes running WebSphere Application Server V7 and later. To run Web Services Security applications utilizing secure conversation in this environment, enable the following property for the V7.0 and later nodes in the cluster: com.ibm.ws.wssecurity.distributedcache.PreV70InteropMode.

This property ensures that the method for adding entries in the cache is consistent between the different nodes, and also allows the applications to interoperate. To enable the property:

1. In the WAS console, click Servers > Server Types > WebSphere application servers.

2. Click the server name.

3. Under the Security section, click security runtime.

4. Click Custom properties.

5. Click New.

6. Enter the property name, com.ibm.ws.wssecurity.distributedcache.PreV70InteropMode, in the Property name field. Enter the property value of true in the Property value field, then click OK.

7. When the Properties panel is refreshed, the com.ibm.ws.wssecurity.distributedcache.PreV70InteropMode property appears in the properties table.

8. Click Save to commit the change.

9. Restart the server to load the new property.

Results

Secure conversation is now enabled for Web Services Security applications running in a mixed cluster environment.
