For failover configuration with Oracle 9i I have used
two database in same m/c. and the listner.ora is as following :-

LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC3))
      )
      (ADDRESS_LIST =
        (ADDRESS = (PROTOCOL = TCP)(HOST = tcs052640)(PORT = 1521))
      )
    )
  )

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
      (SID_NAME = PLSExtProc)
      (ORACLE_HOME = D:oracleora_home)
      (PROGRAM = extproc)
    )
    (SID_DESC =
      (ORACLE_HOME = D:oracleora_home)
      (SID_NAME = SPACE)
    )
    (SID_DESC =
      (ORACLE_HOME = D:oracleora_home)
      (SID_NAME = UIIVS2)
    )
  )

And TNS Entry which i have used in a m/c. which has only oracle client is like the following :-

PROD.WORLD =
  (DESCRIPTION_LIST =
    (FAILOVER = TRUE)
    (LOAD_BALANCE = FALSE)
    (DESCRIPTION =
    (ADDRESS =
      (PROTOCOL = TCP)
      (HOST = TCS052640)(PORT = 1521))
      (CONNECT_DATA =
        (SERVICE_NAME = SPACE.WORLD)
        (SERVER = DEDICATED)
      )
    )
    (DESCRIPTION =
    (ADDRESS =
      (PROTOCOL = TCP)
      (HOST = TCS052640)(PORT = 1521))
      (CONNECT_DATA =
        (SERVICE_NAME = UIIVS2.WORLD)
        (SERVER = DEDICATED)
      )
    )
  )

Now i am connected to SPACE from that m/c. which has only Oracle 9i client and then shutdown the database SPACE, but
after shutting down client is not dynamically connecting to the database UIIVS2,though I have written "FAILOVER = TRUE" in tnsnames.ora.

It is giving error like :-
ORA-12571: TNS:packet writer failure
ORA-03114: not connected to ORACLE
& when I am attempting test connection it is giving error
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist

What more I have to do for connecting dynamically UIIVS2 when SPACE is down.
If the database located in separated m/c. is there anything more need to do.

Thanks in advance.
