WebLogic Server: Investigating Transaction Problems Support Pattern (Doc ID 1332274.1)

Last updated on SEPTEMBER 27, 2023

Applies to:

Oracle WebLogic Server - Version 9.2 and later
Information in this document applies to any platform.


This document discusses how to troubleshoot and fix issues involving JTA transactions.

Problem Description

Transactions are a central point in WebLogic Server that bring different systems and technologies together. Problems and misconfiguration in other systems such as databases may cause transaction coordination in WebLogic Server to fail.

This pattern gives some background information about the transaction subsystem of WebLogic Server (JTA, JTS). It also provides information on exceptions and errors that result from transaction problems. In addition, it gives information about transaction-related properties like timeouts as well as JDBCConnectionPool or DataSource properties that have an influence on the transactional behavior of WebLogic Server.
