単一ノードのリスナーで別IP・同じポート番号でリスンできるか

• /u01/app/oracle/product/10.2.0/db_1/network/admin/listener.ora

LISTENER=
        (DESCRIPTION=
                (ADDRESS_LIST=
                        (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.153.17)(PORT=1521))
                        (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.233.17)(PORT=1521))
                        (ADDRESS=(PROTOCOL=ipc)(KEY=extproc))))

SID_LIST_LISTENER=
        (SID_LIST=
                (SID_DESC=
                        (GLOBAL_DBNAME=orcl)
                        (ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1)
                        (SID_NAME=orcl)))

listener.ora はこんな具合。
リスナーを起動すると、

$ lsnrctl start
...
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.153.17)(PORT=1521)))
Listening on: (DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.233.17)(PORT=1521)))
...

問題なく起動できてるようだ。
リモートから sqlplus で接続してみると、

$ sqlplus system/manager@192.168.153.17:1521/orcl
...
Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options

接続成功。。。
