Hello,
Thank you for your query. In Rational Performance Tester, there is no test extension specific to test databases as the primary interface. Using TCP/IP (socket level record/playback) for SQL database record/playback is a futile exercise in general. A better approach is to either:
1) Use custom code using JDBC to access the DB, but this can be very low level (lots of calls), or
2) As DB2 folks do, write an EJB on the app server that does the DB2 communication, and then use custom code to call the (higher level) EJB.
We hope this helps answer your question.
