WebSphere Application Server StaleConnectionExceptions
A StaleConnectionException is an exception that is generated by the WebSphere Application Server database connection code when a JDBC driver returns a fatal error from a connection request or operation. Configuring a WebSphere Application Server datasource includes specifying a datasource helper class, which is selected depending on your JDBC driver type, for example, DB2UniversalDataStoreHelper for DB2, Oracle11gDataStoreHelper for Oracle 11g, etc. Each helper class contains a list of driver specific error codes associated with fatal...

WebSphere Message Broker and JDBC
Sometimes the simple things can seem difficult, but configuring JDBC with Message Broker is a pretty straight forward task. Typically, you are connecting to a database from a message flow application, which requires you to configure the message flow node that indicates the actual database call, a JDBC configurable service defined at the broker level, which allows the database call to be sent to the correct database and security, so that the DB knows who is making that call. There are several built-in nodes provided in WebSphere Message Broker... [More]

Wouldn't you want a DB2 JDBC Driver trace that can survive WebSphere Application Server on z/OS recylce?
Recently, I faced a challenge in debugging a problem where the Java Data Base Connectivity (JDBC) trace is either overwritten or lost upon the WebSphere Application Server recycle on z/OS. Specifying the JDBC trace file with the default options provided by the DB2 Universal JDBC Driver data source Custom properties settings, (which you would normally do) will cause the driver to create a new JDBC trace file if the server is recycled. With many installations using the Automatic restart manager (ARM) facility for the servers, if we... [More]

Using the RRA trace group in WebSphere Application Server to determine elapsed time for SQL operations
Have you ever suspected that your JDBC operations might be causing some performance problems in your application? One easy way to examine your system for lengthy JDBC operations is to utilize the PMI system in WebSphere Application Server. PMI or Performance Monitoring Infrastructure is a service provided in the WebSphere run time to collect performance-related metrics for administrator review. While there are suitable metrics provided by PMI to tell you how long your JDBC calls are taking on average, it cannot tell you the exact elapsed time... [More]
