  1. Jacco,
    in “2012 – Configure JDBC data sources for RAC” in the page on Connection Testing you say: ‘then change the query to “show user”‘. show user is sqlplus lingo and will raise an error when used (java.sql.SQLSyntaxErrorException: ORA-00933: SQL command not properly ended), what did you mean as query for the testing of physical database connections? SELECT USER FROM DUAL?

    I just got this question from someone who saw your paper and was a bit suprised you mentioned this.

    Kind regards,
    Andre van Winssen

    • Hi Andre,

      You are absolutely correct. Somehow I only tested if the statement was accepted and no actual errors appeared upon connection testing (I just validated using the gridlink test application). Thanks for letting me know!

      Additionally I uploaded the slides I used the last time I presented about this topic.
