修改OracleRAC监听端口号:

修改前一定要查看修改后的端口有没有被占用：

# netstat -an|grep <new-listener-port>

1、查看当前数据库监听状态：

（grid用户执行）

$ lsnrctl status

$ srvctl config listener

示例：

[+ASM1][grid@ceshi1 ~]$ lsnrctl status

LSNRCTL for Linux: Version 11.2.0.4.0 - Production on 05-APR-2022 06:34:12

Copyright (c) 1991, 2013, Oracle.  All rights reserved.

Connecting to (ADDRESS=(PROTOCOL=IPC)(KEY=EXTPROC0))

STATUS of the LISTENER

------------------------

Alias                     LISTENER

  Instance "orcl1", status BLOCKED, has 1 handler(s) for this service...

Service "test" has 1 instance(s).

  Instance "orcl1", status BLOCKED, has 1 handler(s) for this service...

The command completed successfully

[+ASM1][grid@ceshi1 ~]$ srvctl config listener

Name: LISTENER

Network: 1, Owner: grid

Home: <CRS home>

End points: TCP:1522

2、修改集群监听端口：

修改监听端口：（grid用户单节点执行）

$ srvctl modify listener -l LISTENER -p "TCP:<new-listener-port>"

修改scan端口：（grid用户单节点执行）

$ srvctl modify scan_listener -p <new-scan-port>

示例：

[+ASM1][grid@ceshi1 ~]$ srvctl modify listener -l LISTENER -p "TCP:1533"

[+ASM1][grid@ceshi1 ~]$ srvctl modify scan_listener -p 1533

3、手动修改LOCAL_LISTENER：

（oracle用户所有节点执行）

SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=<Host-name>)(PORT=<new-port-number>))))' scope=both sid='[<your-chosen-instance> | * ] '

注意:按照实例所在节点修改"IP"和"实例名"

示例：

节点一：

#修改LOCAL_LISTENER

[orcl1][oracle@ceshi1 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4.0 Production on Tue Apr 5 07:26:34 2022

Copyright (c) 1982, 2013, Oracle.  All rights reserved.

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,

Data Mining and Real Application Testing options

SQL> alter system set local_listener ="(ADDRESS=(PROTOCOL=TCP)(HOST= 192.168.48.130)(PORT=1533))" SID='orcl1';

System altered.

#查看LOCAL_LISTENER

SQL> show parameter LOCAL_LISTENER

NAME				     TYPE	 VALUE

------------------------ ------- ------------------------------

local_listener			 string	 (ADDRESS=(PROTOCOL=TCP)(HOST=192.168.48.130)(PORT=1533))

节点二：

#修改LOCAL_LISTENER

[orcl2][oracle@ceshi2 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.4.0 Production on Wed Apr 6 02:50:46 2022

Copyright (c) 1982, 2013, Oracle.  All rights reserved.

Connected to:

Oracle Database 11g Enterprise Edition Release 11.2.0.4.0 - 64bit Production

With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP,

Data Mining and Real Application Testing options

SQL> alter system set local_listener ="(ADDRESS=(PROTOCOL=TCP)(HOST= 192.168.48.131)(PORT=1533))" SID='orcl2';

System altered.

#查看LOCAL_LISTENER

SQL> show parameter LOCAL_LISTENER

NAME				     TYPE	 VALUE

------------------------ ------- ------------------------------

local_listener			 string	 (ADDRESS=(PROTOCOL=TCP)(HOST=192.168.48.131)(PORT=1533))

若移除监听（REMOTE_LISTENER）也需要进行类似更改

4、停止集群监听和SCAN：

停止监听和scan：（grid用户单节点执行）

$ srvctl stop listener [-l <lsnr_name>] [-n <node_name>] [-f]

$ srvctl stop scan [-i <ordinal_number>] [-f]

$ srvctl stop scan_listener [-i <ordinal_number>] [-f]

示例：

$ srvctl stop listener -l LISTENER

$ srvctl stop scan_listener

5、修改listener.ora文件：

修改listener.ora文件中的端口信息：（grid用户所有节点执行）

$ vi $GRID_HOME/network/admin/listener.ora

LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER))))            # line added by Agent

LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1))))                # line added by Agent

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON                # line added by Agent

ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON              # line added by Agent

LISTENER =

    (ADDRESS_LIST =

        (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

        (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.48.130)(PORT = 1522))

    )

将默认侦听器配置文件下的（端口=1521）更改为所需的值。如果您没有此文件，则可以使用以下示例：
LISTENER =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

(ADDRESS = (PROTOCOL = TCP)(HOST = myhostname)(PORT = myport))

)
若配置了$GRID_HOME/network/admin/tnsnames.ora文件也需要进行端口调整

6、启动集群监听和SCAN：

启动监听和scan：（grid用户所有节点执行）

$ srvctl start listener [-l <lsnr_name>] [-n <node_name>]

$ srvctl start scan [-i <ordinal_number>] [-n <node_name>]

$ srvctl start scan_listener [-n <node_name>] [-i <ordinal_number>]

示例：

#启动集群监听和SCAN

$ srvctl start listener -l LISTENER

$ srvctl start scan_listener

7、验证数据库监听端口状态：
