JDBC url for oracle RAC

If you have to connect to oracle RAC (Real Application Cluster) using JDBC with thin driver, the classic url:

jdbc:oracle:thin:@<HOST>:1521:<SID>

doesn’t work and you get the error ORA – 12505.
Instead, you must use this url:

jdbc:oracle:thin:@(DESCRIPTION=(LOAD_BALANCE=on)
(ADDRESS=(PROTOCOL=TCP)(HOST=host1) (PORT=1521))
(ADDRESS=(PROTOCOL=TCP)(HOST=host2) (PORT=1521))
(CONNECT_DATA=(SERVICE_NAME=service)))

If you have an oracle client, like toad, check the tsnames.ora for the correct values of SERVICE_NAME and host.

Some oracle forum posts seems to suggest that there is some issue with DB, but this post really helped.

Unfortunately for me even this didn’t work. I’m using a WebSphere 5 server with connection pools on a system with a 9i client connecting to a 10g RAC. When the client didn’t work I tried using jdbc as above, however I still get : Connection not available while invoking method queueRequest for resource jdbc/racserver. I can test the connection successfully but can’t create a pooled connection. J2CA0020E: The Connection Pool Manager could not allocate a Managed Connection: com.ibm.websphere.ce.j2c.ConnectionWaitTimeoutException

I kept getting this error over and over. I was hoping that a simple copy paste will solve it, as I just got sooooo annoyed from trying to solve it in the last 2 hours… and praise the lord it worked :) Changing the URLs as u stated did the trick and the connection worked flawlessly.

THANKS A LOT !
