FAILOVER clause in tnsnames entry

Hi,

We have a 11g RAC database. 11.2.0.3 to be precise.
There are 2 nodes

We have the following tnsnames entry to connect to this database using "TEST" service


TEST =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.10.10)(PORT = 1521))
    (ADDRESS = (PROTOCOL = TCP)(HOST = 10.10.10.11)(PORT = 1521))
    (LOAD_BALANCE = yes)
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test.db.net)
      (FAILOVER_MODE =
              (TYPE = SELECT)
              (METHOD = BASIC)
              (RETRIES = 180)
              (DELAY = 5)
      )
    )
  )
