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.

About 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 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.

Procedure

When WebSphere Application Server global security is enabled for application servers at WebSphere® Application Server Version 6.0.2 or later, you must disable protocol security on such servers in the following situations:

The protocol security setting controls only the transaction protocol messages between servers that are used to coordinate the completion of a transaction. It does not affect application messages or the security of the server.

To disable protocol security on a server, complete the following steps in the administrative console:

  1. In the administrative console, click Servers > Application Servers > server_name This action displays the properties of the application server in the content pane.
  2. Under Container Settings, expand Container Services and click Transaction Service to display the properties page for the transaction service.
  3. Under Additional Properties click Custom Properties.
  4. On the Custom Properties page, click New.
  5. Type DISABLE_PROTOCOL_SECURITY in the Name field and type TRUE in the Value field.
  6. Click Apply or OK.
  7. Click Save to save your changes to the master configuration.
  8. Restart the server.
This custom property controls only those inter-server transaction protocol messages that are used to coordinate the completion of a transaction, and is unrelated to application messages. This custom property is involved with prepare, commit, rollback and commit_one_phase messages. The property controls whether the server verifies that the sending server is authorized to perform this action. The security of the server is not affected by setting this custom property to true.
