Configuring a server to use business activity support

Business activity support provides compensation for activities such as sending an email, which can be difficult or impossible to roll back atomically. With this compensation, applications on disparate systems can coordinate activities that are more loosely coupled than atomic transactions. To use the business activity support, you must first enable it on each server that you plan to use.

About this task

If an application component uses business activity support, you must enable the support on each server that runs the application.

New feature New feature: This topic references one or more of the application server log files. Beginning in WebSphere Application Server Version 8.0 you can configure the server to use the High Performance Extensible Logging (HPEL) log and trace infrastructure instead of using SystemOut.log , SystemErr.log, trace.log, and activity.log files or native z/OS logging facilities. If you are using HPEL, you can access all of your log and trace information using the LogViewer command-line tool from your server profile bin directory. See the information about using HPEL to troubleshoot applications for more information on using HPEL.newfeat

Procedure

  1. In the administrative console, click Servers > Server Types > WebSphere application servers > server_name > [Container Settings] Container Services > Compensation Service.
  2. Select the Enable service at server startup check box.
  3. If required, modify the compensation handler retry interval and limit. These values control the frequency with which the compensation handler compensate and close methods are retried, when either throw a RetryCompensationHandlerException exception, and the number of times that these methods are retried.
  4. Save your changes to the master configuration.
  5. Repeat the previous steps for each server that you plan to use.
  6. Restart all the servers for the changes to take effect.

Results

The business activity support is enabled for the application server. Verify a successful enablement by checking for the message, CWSCP0005I: The Compensation service started successfully. in the SystemOut.log file for the relevant server.
