We are trying to move to the Oracle RAC and use TAF in our organization. Does jdbc thin driver v. 10.2.0.4.0 support TAF?

In the jdbc connection string we have FAILOVER=on|off What is the usage for this option?

jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = node 1 IP)(PORT = 1521))(ADDRESS = (PROTOCOL = TCP)(HOST = node 2 IP)(PORT = 1521))((FAILOVER = on)(LOAD_BALANCE = off)(CONNECT_DATA =(SERVICE_NAME = sid)(FAILOVER_MODE =(TYPE = SELECT)(METHOD = BASIC)(RETRIES = 160)(DELAY = 5))))

The fact that you put an option in the connection string does not prove that it is actually used.

I ran a test against Oracle RAC with the TAF configured: set up web application on JBoss to use jdbc thin driver and changed the first node's IP to 1.1.1.1. It actually worked - must of used second (good) IP despite what documentation states.

You did it before connection time, not during the session.

How about DBD, Perl driver for Oracle? Does it have any support for TAF? Failover support during the connection time would suffice.

I think it should depend on the version and I'm not sure it does it even in the latest version. Just have a look a the documentation of your DBD:Oracle module.

Is there a commercial Oracle driver for Perl that supports TAF?
