Last updated on MAY 19, 2021

Applies to:

Oracle WebLogic Server - Version 6.1 to 8.1
Information in this document applies to any platform.

Purpose

Reference For Troubleshooting WebLogic Server Issues (WLS Support Patterns) <Note 1189504.1> > Primary Note on Oracle WebLogic Server JTA/JTS/Transaction Support Patterns <Note 761116.1> > Note 779556.1
This document discusses how to troubleshoot and fix issues involving JTA transactions. Please note that this article discusses older versions of WLS: 6.1 to 8.1. For discussion of WLS 9.2.x and higher, please see the updated version of this support pattern at WebLogic Server: Investigating Transaction Problems Support Pattern <Note 1332274.1>.

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.
