Business activity support provides compensation for activities
such as sending an e-mail, 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.
Procedure
- In the administrative console, click .
- Select the Enable service at server startup check
box.
- 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.
- Save your changes to the master configuration.
- Repeat the previous steps for each server that you plan
to use.
- 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.
What to do next
Deploy the business-activity-enabled application to the server.
