If your application displays JDBC-related exception messages, activate the JDBC trace service. The resulting log text can help you identify the problem.
Trace strings for JDBC data sources
Set trace for the previously mentioned JDBC drivers through data source custom properties. For example, use custom property spyAttributes to enable the JDBC trace for SequeLink or Connect JDBC drivers. Consult your driver documentation for details on the custom property that enables trace for your JDBC implementation.
Additional resources
If the JDBC tracing service cannot help you isolate and fix your problem, consult the IBM Support website for WebSphere Application Server at http://www.ibm.com/support/search.wss?rs=180&tc=SSEQTP&tc1=SSCMP9Y. Use the site search function to find current information on known problems and their resolutions. Locating the right troubleshooting tip can save time that, otherwise, you might spend on opening and tracking a PMR.
