1 instance membuat banyak listener Oracele 11g di Linux

1. umumnya konfigurasi listener adalah sebagai berikut
[oracle@orcl4 u01]$ vi /u01/app/oracle/product/11.1.0/db_1/network/admin/listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = orcl4.localdomain)(PORT = 1521))
)
)

2. setelah listener dijalankan & status
[oracle@orcl4 u01]$ lsnrctl start listener
[oracle@orcl4 u01]$ lsnrctl status listener

3. agar listener daat berjalan lebih dari 1 port, maka dapat dilakukan perubahan konfigurasi pada listener.ora pada server
[oracle@orcl4 u01]$ vi /u01/app/oracle/product/11.1.0/db_1/network/admin/listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = orcl4.localdomain)(PORT = 1521))
)
)

LISTENER2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = orcl4.localdomain)(PORT = 1522))
)
)

SID_LIST_LISTENER2 =

)
)

4. restart listener
[oracle@orcl4 u01]$ lsnrctl stop
[oracle@orcl4 u01]$ lsnrctl start listener2
