Following the upgrade of a development db from Oracle 8.1.6 to Oracle 8.1.7 we are experiencing problems when connecting from a third party app running on Weblogic using JDBC. We have already updated the drivers to the latest drivers as download from OTN.

Has anyone else experienced similar problems? Any ideas or suggestions would be appreciated.

Error message in jdbc.log:

DRVR FUNC DBError.throwSqlException(reason="READ_COMMITTED and SERIALIZABLE are the only valid transaction levels", SQLState=null, vendorCode=17030)
SQLException: SQLState(null) vendor code(17030)
java.sql.SQLException: READ_COMMITTED and SERIALIZABLE are the only valid transaction levels
at java.lang.Throwable.fillInStackTrace(Native Method)

I was unable to find any further information about this JDBC error in the documentation...
