Thin Client connection not failing over

Question

I'm using the following thin client connection and the sessions do not failover. Test with SQLPLUS and the sessions do fail over. One difference I see between the two different connections is the thin connection has NONE for the failover_method and failover_type but the SQLPLUS connection show BASIC for failover_method and SELECT for failover_type.
Is there any issues with the thin client the version is 10.2.0.3
jdbc:oracle:thin:@(description=(address_list=(load_balance=YES)(address=(protocol=tcp)(host=crpu306-vip.wm.com)(port=1521))(address=(protocol=tcp)(host=crpu307-vip.wm.com)(port=1521)))(connect_data=(service_name=ocsqat02)(failover_mode=(type=select)(method=basic)(DELAY=5)(RETRIES=180))))

Answer 1

You have to use (FAILOVER=on) as well on jdbc url.

Example: TAF with Connect-Time Failover and Client Load Balancing
Implement TAF with connect-time failover and client load balancing for multiple addresses. In the following example, Oracle Net connects randomly to one of the protocol addresses on sales1-server or sales2-server. If the instance fails after the connection, the TAF application fails over to the other node's listener, reserving any SELECT statements in progress.sales.us.acme.com=
(DESCRIPTION=
*(LOAD_BALANCE=on)*
*(FAILOVER=on)*
(ADDRESS=
(PROTOCOL=tcp)
(HOST=sales1-server)
(PORT=1521))
(ADDRESS=
(PROTOCOL=tcp)
(HOST=sales2-server)
(PORT=1521))
(CONNECT_DATA=
(SERVICE_NAME=sales.us.acme.com)
*(FAILOVER_MODE=*
*(TYPE=select)*
*(METHOD=basic))))*
Example: TAF Retrying a Connection
TAF also provides the ability to automatically retry connecting if the first connection attempt fails with the RETRIES and DELAY parameters. In the following example, Oracle Net tries to reconnect to the listener on sales1-server. If the failover connection fails, Oracle Net waits 15 seconds before trying to reconnect again. Oracle Net attempts to reconnect up to 20 times.sales.us.acme.com=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=tcp)
(HOST=sales1-server)
(PORT=1521))
(CONNECT_DATA=
(SERVICE_NAME=sales.us.acme.com)
*(FAILOVER_MODE=*
*(TYPE=select)*
*(METHOD=basic)*
*(RETRIES=20)*
*(DELAY=15))))*
