• WebLogic Tuxedo Connector Leads to Out of Memory Errors

  Using WebLogic Tuxedo Connector (WTC) in WLS leads to an OutOfMemoryError (OOME). This is a generic error and there can be many reasons for this to occur. <Note 1135105.1>

• Troubleshooting J2CA Connection Pooling Issues in WebLogic Server

  This support pattern shows how the Connector Layer within WebLogic Server interacts with the deployed J2CA Adapter and WebLogic's Transaction Manager. Debug properties can be used to view the lifecycle of a pooled connection, of a local transaction, and of a distributed XA transaction. Information is based on how J2CA is implemented in the WLS 8.1 release. Because J2CA is an interoperability standard, troubleshooting is dependent on specific knowledge of WebLogic Server, J2CA, and the EIS being accessed. This pattern seeks instead to show a baseline behavior of the two areas of most complex interaction between WebLogic and the J2CA Adapter: connection handling and transaction handling. Deviations from this baseline can then be more easily spotted by both adapter developers and application deployers. <Note 1135134.1>
