Enabling server-wide Last Participant Support

To complete the integration of WebSphere® MQ, you enable Last Participant Support.

About this task

To finish integrating WebSphere MQ in WebSphere Application Server for asynchronous execution, you enable Last Participant Support (LPS) so that a single one-phase commit resource is used with any number of two-phase commit resources in the same global transaction. To do so, you set the ACCEPT_HEURISTIC_HAZARD custom property to true in the Integrated Solutions Console and then restart the application server.

Procedure

To enable server-wide LPS:

  1. Open the Integrated Solutions Console.
  2. Click Servers  > Server Types > WebSphere application servers and the server name.

    The properties page for the application server opens

  3. Under Container Settings, expand Container Services and click Transaction Service.

    The properties page for the transaction service opens.

  4. Under Additional Properties, click Custom properties.
  5. On the Custom Properties page, click New and type ACCEPT_HEURISTIC_HAZARD as the Name and TRUE as the Value.
  6. Click Apply and Save directly to the master configuration.
  7. Restart your application server.
