WebLogic: The Definitive Guide

Overview

A transaction encapsulates a sequence of operations that are treated as a single atomic unit. The results of the operations within a transaction are committed only if all the operations are completed successfully. Otherwise, the transaction is rolled back and all changes resulting from the operations are abandoned. Regardless of whether the changes are committed or rolled back, the resources participating in the transaction must always be left in a consistent state. Intermediate changes made during the lifetime of a transaction are isolated from the outside world — they remain invisible until the transaction has completed. A transaction, if completed successfully, must ensure the changes are persistent or durable.

WebLogic Server provides the infrastructure for transaction management and guarantees the integrity of your transactions. As a TP monitor, WebLogic can manage transactions and coordinate access across various enterprise stores, including a relational database, JMS servers, or any transaction-aware resource. WebLogic guarantees that updates to multiple resources occur correctly and accurately when a transaction completes successfully, and the entire transaction rolls back if any of the operations fail.

JDBC Transactions
