[Quoted] You would write SQL based on how interesting the Optimizer will make your life trying to figure out why it doesn't work as expected. [JDBC and ODBC support] changed during those timeframes, [TAF and FCF] in a RAC environment. etc. SQL itself may not be the issue in the RAC environment it is how you handle errors in your code - like a database instance on node1 going down but nodes 2-4 are still up... how do you handle the error and reconnect. Lot's of fun.

As an Oracle developer you have LOTS to learn ;) Received on Mon Mar 02 2009 - 21:31:57 CET
