 Hello,

 

I have a production RAC system with a database named DTBS, instances DTBS1 and DTBS2.

Here is the entire tnsnames.ora file from the RAC nodes, and you can see how TAF entry is configured:

 

DTBS =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-cc1-vip)(PORT = 1521))

    (ADDRESS = (PROTOCOL = TCP)(HOST = rac2-cc1-vip)(PORT = 1521))

    (LOAD_BALANCE = yes)

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = DTBS)

    )

  )    

 

DTBS2 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = rac2-cc1-vip)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = DTBS)

      (INSTANCE_NAME = DTBS2)

    )

  )

 

DTBS1 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = rac1-cc1-vip)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = DTBS)

Howdy, Stranger!
