Chapter 12. Configuring the transactions subsystem

When you manage an enterprise application that processes financial transactions, order management, or other critical workflows, you need to ensure reliable operations and data consistency. The transactions subsystem in JBoss EAP gives you full control over the Transaction Manager ™, letting you configure timeout values, enable transaction logging, and collect statistics. If your application runs across multiple systems and transaction propagation is required then at least one of JBoss Remoting or JTS needs to be enabled.

JBoss EAP uses the Narayana transaction manager to handle transactions efficiently. It supports industry-standard protocols like Jakarta Transactions, JTS, and Web Services Transactions. Whether you update databases, send messages, or coordinate distributed services, the transactions subsystem ensures consistency, reliability, and resilience.
