# Create a new listener with different port numbers 
##########################

We are going to add a new listener named lsnr_10g_1533 Which is going to use port 1533

#  1) Check how Many Listeners are Running

#  2) Find the home where other Listeners are Running
##########################

Here Our listeners are running in ASM HOME

##########################
#  3) Edit Listener.ora
##########################

Add below entry in LISTENER.ORA file.

Here we are using a different Port number 1533. Default port is 1521. And also in SID_LIST_LSNR_10G_1533, we are specifying for which databases the listener has to listen.

LSNR_10G_1533 =
  (DESCRIPTION_LIST =
    (DESCRIPTION =
      (ADDRESS = (PROTOCOL = TCP)(HOST = my_server.com)(PORT = 1533)(QUEUESIZE=99))
    )
  )

SID_LIST_LSNR_10G_1533 =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = mydb_1.com)
      (ORACLE_HOME = /opt/oracle/product/10.2/db_a)
      (SID_NAME = mydb_1)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = mydb_2.com)
      (ORACLE_HOME = /opt/oracle/product/10.2/db_a)
      (SID_NAME = mydb_2)
    )
  )

## 6) Test whether new listener working or not
##########################

Add below TNS entry in TNSNAMES.ora and try connecting the database with this newly created listener.

mydb_2_1533.com =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = my_server.com)(PORT = 1533))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
