An administrator can control a number of domain-level Transaction Service settings. For details, see Configuring the Transaction Service.
The Transaction Timeout setting can be overridden by a bean. See Bean-Level Container-Managed Transaction Timeouts.
In addition, the administrator can monitor transactions using statistics from the transaction manager that provide information on such activities as the number of transactions completed, rolled back, or recovered since server startup, and transactions presently being processed.
For information on administering and monitoring transactions, select the Transaction Service component under the relevant configuration in the Admin Console and click the Help button. Also see Chapter 10, Transactions, in Sun Java System Application Server Platform Edition 9 Administration Guide.
