一、修改SCAN listener port

To modify SCAN listener port As grid user:

1.1 修改SCAN listener port

1.Modify SCAN listener port: $GRID_HOME/bin/srvctl modify scan_listener -p Update 11gR2 database init.ora parameter: alter system set remote_listener=':' scope=both;

示例：

[grid@jyracdb1 ~]$ $GRID_HOME/bin/srvctl modify scan_listener -p 1522
[oracle@jyracdb1 ~]$ sqlplus / as sysdba

1.2 重启SCAN listener生效新端口

2.Restart SCAN listener so the new port will be effective: $GRID_HOME/bin/srvctl stop scan_listener $GRID_HOME/bin/srvctl start scan_listener

示例：

[grid@jyracdb1 ~]$ $GRID_HOME/bin/srvctl stop scan_listener
[grid@jyracdb1 ~]$ $GRID_HOME/bin/srvctl start scan_listener

1.3 确认更改

3.Confirm the change: $GRID_HOME/bin/srvctl config scan_listener

示例：

[grid@jyracdb1 ~]$ $GRID_HOME/bin/srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1522

二、修改Listener Ports

首先获取当前你的监听程序的配置信息.

To get the current settings of your listener on RAC issue the following command: srvctl config listener The output should be similar to the following Name: LISTENER Network: 1, Owner: oracle Home: End points: TCP:1521

示例：

[grid@jyracdb1 ~]$ srvctl config listener
Name: LISTENER
Network: 1, Owner: grid
Home: <CRS home>
End points: TCP:1521

2.1 修改端口

(1) Amend the ports used with a command similar to the following srvctl modify listener -l LISTENER -p "TCP:" This changes the entry in OCR, so that a listener restart will pick up the new values. Existing connections will remain connected.

示例：

[grid@jyracdb1 ~]$ srvctl modify listener -l LISTENER -p "TCP:1522"

2.2 手工修改LOCAL_LISTENER

(3) LOCAL_LISTENER should be changed manually An example would be SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=)(PORT=))))' scope=both sid='[<your-chosen-instance| * ] '

示例：

[oracle@jyracdb1 ~]$ sqlplus / as sysdba

SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.99.192)(PORT=1522))))' scope=both sid='racdb1';

System altered.

SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.99.194)(PORT=1522))))' scope=both sid='racdb2';

System altered.

SQL> show parameter listener

NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
listener_networks                    string
local_listener                       string      (DESCRIPTION=(ADDRESS_LIST=(AD
                                                 DRESS=(PROTOCOL=TCP)(HOST=192.
                                                 168.99.192)(PORT=1522))))
remote_listener                      string      jyracdb-scan:1522
#注：节点2的local_listener输出也就是host不同。

2.3 重新启动监听程序

监听重新启动后，对应配置文件才会更改。

(5) endpoints_listener.ora and local_listener.ora for each SID are only changed after the listener is stopped and restarted.

示例：

[grid@jyracdb1 admin]$ srvctl stop listener
[grid@jyracdb1 admin]$ srvctl start listener

2.4 检查监听配置

(6) Check the configuration afterwards with "srvctl config Listener".

示例：

[oracle@jyracdb1 ~]$ srvctl config Listener
Name: LISTENER
Network: 1, Owner: grid
Home: <CRS home>
End points: TCP:1522
