Configuring last participant support for an application server

To configure last participant support (LPS) for an application server, you set the ACCEPT_HEURISTIC_HAZARD custom property for the transaction service for that server. In this way, all applications that run on that server are enabled for LPS.

About this task

Last participant support is an extension to the transaction service that enables a single one-phase resource to participate in a two-phase transaction with one or more two-phase resources.

You configure LPS for an application server to specify that all applications on this server accept the possibility of a heuristic hazard occurring in a two-phase transaction that contains a one-phase resource.

If you do not set this property, or you set this property to FALSE, LPS behavior depends on the LPS setting of the application. You must configure applications individually to accept the heuristic hazard.

You can configure applications individually either when they are assembled, or following deployment by using the administrative console and the Last participant support extension settings.

To configure LPS for an application server using the administrative console, use the following steps.

Procedure

  1. From the navigation pane of the administrative console, click Servers > Application servers > server_name > [Container Settings] Container Services > Transaction Service > [Additional Properties] Custom Properties.
  2. Click New.
  3. Type ACCEPT_HEURISTIC_HAZARD in the Name field, and TRUE in the Value field.
  4. Click Apply or OK.
  5. Save your changes to the master configuration.
  6. Restart the server.
