大多数现场集群都采用的是默认端口，现XX现场客户领导要求不使用默认端口，以下是修改监听端口的步骤，配置过程中若有疑问可添加文末公众号发私信一对一答疑解惑。

一.修改SCAN listener port

1.1 修改SCAN listener port

1.1.1.crs配置中修改SCAN listener port

--切换到grid用户
su - grid--修改前查看SCAN listener 状态
[grid@orcl01:/home/grid]$ srvctl status scan_listener
SCAN Listener LISTENER_SCAN1 is enabled
SCAN listener LISTENER_SCAN1 is running on node orcl01--修改前查看SCAN listener 配置信息
[grid@orcl01:/home/grid]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1521--修改成新的端口   1个节点更改所有节点生效
[grid@orcl01:/home/grid]$ srvctl modify scan_listener -p 1522

1.1.2.数据库中修改SCAN listener port

--切换到oracle用户
su - oracle
sqlplus / as sysdba--修改前查看
SQL> set linesize 100
SQL> show parameter listenerNAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
listener_networks		     string
local_listener			     string	  (ADDRESS=(PROTOCOL=TCP)(HOST=192.168.40.202)(PORT=1521))
remote_listener 		     string	 orcl-scan:1521--更改SCAN listener port   
SQL> alter system set remote_listener='orcl-scan:1522'  sid='*' scope=both;
System altered.--更改后查看
SQL> show parameter listenerNAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
listener_networks		     string
local_listener			     string	  (ADDRESS=(PROTOCOL=TCP)(HOST=192.168.40.202)(PORT=1521))
remote_listener 		     string	 orcl-scan:1522

1.1.3 重启SCAN listener生效新端口

--切换到grid用户
su - grid--重启SCAN listener生效新端口
[grid@orcl01:/home/grid]$ srvctl stop scan_listener
[grid@orcl01:/home/grid]$ srvctl start scan_listener

1.1.4 确认更改

--切换到grid用户
su - grid[grid@orcl01:/home/grid]$ srvctl config scan_listener
SCAN Listener LISTENER_SCAN1 exists. Port: TCP:1522

二.修改Listener Ports

2.1 获取当前监听程序的配置信息

--切换到grid用户
su - grid--查看当前监听程序的配置信息
[grid@orcl01:/home/grid]$ srvctl config listener
Name: LISTENER
Network: 1, Owner: grid
Home: <CRS home>
End points: TCP:1521

2.2 crs中修改LOCAL_LISTENER

--切换到grid用户
su - grid--手工修改LOCAL_LISTENER  1个节点更改所有节点生效
[grid@orcl01:/home/grid]$ srvctl modify listener -l LISTENER -p "TCP:1522"--修改后查看当前监听程序的配置信息
[grid@orcl01:/home/grid]$ srvctl config listener
Name: LISTENER
Network: 1, Owner: grid
Home: <CRS home>
End points: TCP:1522

2.3.数据库中修改LOCAL_LISTENER

2.3.1.修改前查看LOCAL_LISTENER

节点1和节点2的ip地址分别对应vip

--切换到oracle用户
su - oracle
sqlplus / as sysdba--修改前查看 节点1
SQL> set linesize 100
SQL> show parameter listenerNAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
listener_networks		     string
local_listener			     string	  (ADDRESS=(PROTOCOL=TCP)(HOST=192.168.40.202)(PORT=1521))
remote_listener 		     string	 orcl-scan:1522----修改前查看 节点2
SQL> set linesize 100
SQL> show parameter listenerNAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
listener_networks		     string
local_listener			     string	  (ADDRESS=(PROTOCOL=TCP)(HOST=192.168.40.203)(PORT=1521))
remote_listener 		     string	 orcl-scan:1522

2.3.2.更改LOCAL_LISTENER

--切换到oracle用户
su - oracle
sqlplus / as sysdba--更改LOCAL_LISTENER
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.40.201)(PORT=1522))))' scope=both sid='dxj1';System altered.SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.40.203)(PORT=1522))))' scope=both sid='dxj2';System altered.

2.3.3.修改后查看LOCAL_LISTENER

节点1和节点2的ip地址分别对应vip

--切换到oracle用户
su - oracle
sqlplus / as sysdba--修改后查看 节点1
SQL> set linesize 100
SQL> show parameter listenerSQL> show parameter listenerNAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
listener_networks		     string
local_listener			     string	 (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.40.201)(PORT=1522))))
remote_listener 		     string	 orcl-scan:1522----修改后查看 节点2
SQL> set linesize 100
SQL> show parameter listenerNAME				     TYPE	 VALUE
------------------------------------ ----------- ------------------------------
listener_networks		     string
local_listener			     string	 (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.40.203)(PORT=1522))))
remote_listener 		     string	 orcl-scan:1522

2.4 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。

--切换到grid用户
su - grid--重新启动监听程序  1个节点操作即可
[grid@orcl01:/home/grid]$ srvctl stop listener
[grid@orcl01:/home/grid]$ srvctl start listener

2.5 检查配置后的监听程序的配置信息

[grid@orcl01:/home/grid]$ srvctl config Listener
Name: LISTENER
Network: 1, Owner: grid
Home: <CRS home>
End points: TCP:1522
