          Hello;

          Oracle 10 and 11 for sure.

          I don't see why the 9 client won't work.

          Additional information :

          Prerequisites Required For Automatic Client Failover Configurations [ID 405120.1]

          Client Failover Best Practices for Highly Available Oracle Databases: Oracle Database 10g Release 2

          http://www.oracle.com/technetwork/database/features/availability/maa-wp-10gr2-clientfailoverbestprac-129636.pdf

          See - : Typical Wait Times for Client Failover ( which supports my answer )

              I posted the pdf late in my first message.

              It has a chart showing the 9i client and denoted. Is that what you need?

                I think you are looking for this note? *Data Guard 9i Configuring Transparent Application Failover in a Data Guard Environment [ID 205637.1]* its TAF specific to *9i* ?

                      Hello;

                      It goes back to at least 8.0 :

                      8.0.x-8.1.x: Sample config for Transparent Application Failover (TAF) On UNIX [ID 69745.1]

                      I don't remember much from Oracle 7 anymore.

                      h3. But then that's why databases exist.

                      Oracle Fail Safe Concepts and Administration Guide Release 3.2.1 for Windows NT and Windows 2000 A95194-01

                      Not sure this confirms older than 8 but at some point its no longer matters as the Oracle software, the OS and hardware are all desupported. Plus they won't work with anything new.

                        Thanks a lot mseberg.

                        Can you give a link to that .pdf??
                        It's to have a doc of that information that you gave me. I can't access to metalink.

                        Thanks again
