Posted by Mir Sayeed Hassan on March 10th, 2018

Configure multiple IP Address with single default port 1521

sys@TESTDB> select INSTANCE_NAME,VERSION,STATUS from v$instance;

INSTANCE_NAME    VERSION           STATUS
---------------- ----------------- ------------
testdb           11.2.0.4.0        OPEN

Configure the listener

[oracle@testdb admin]$ cat listener.ora
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.120.123)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.120.83)(PORT = 1521))
     (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
    )
  )

ADR_BASE_LISTENER = /u01/app/oracle

Configure the tnsnames

[oracle@testdb admin]$ cat tnsnames.ora
TESTDB =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.120.123)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = testdb)
    )
  )
TESTDB =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.120.83)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = testdb)
    )
  )
