修改Oracle默认监听端口

2017-01-12 09:53:45来源:作者:Linux公社人点击

我们都知道,Oracle的监听默认端口是1521,但是如果系统上1521已经被占用或业务要求不用默认端口,则需要修改监听的默认端口。

修改监听端口只需要修改配置文件listiner.ora,然后重启监听就行了。但是Oracle实例的PMON进程还是会去找监听1521端口的监听进程去注册,所以同时也需要修改数据库的配置。数据库里只需要在线修改LOCAL_LISTINER即可。

下面以11.2.0.4为例测试修改监听端口:

1、修改监听端口

#查看监听状态

[oracle@rhel6 ~]$ lsnrctl status

The listener supports no services

The command completed successfully

至此,监听端口已经修改完毕,这时Oracle实例是无法注册到此监听上的。

2、修改LOCAL_LISTINER参数

#修改参数

sys@ORCL>alter system set local_listener="(address = (protocol = tcp)(host = rhel6)(port = 2521))";

System altered.

#查看监听状态

[oracle@rhel6 ~]$ lsnrctl status

Instance "orcl", status READY, has 1 handler(s) for this service...

The command completed successfully

修改完后,可以看到数据库实例立即注册到监听器上。

3、使用新端口进行测试连接

[c:/~]$ sqlplus zx/zx@192.168.56.2:2521/orcl

SQL*Plus: Release 12.1.0.1.0 Production on 星期六 1月 7 20:24:17 2017

连接到:

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

With the Partitioning, OLAP, Data Mining and Real Application Testing options

SQL>

修改监听端口完成。

4、把Oracle实例的注册端口改回1521

sys@ORCL>alter system set local_listener='';

System altered.

官方文档中还提供了另一种配置LOCAL_LISTINER的方法:

在tnsnames.ora中添加配置,然后配置LOCAL_LISTINER为tnsnames.ora中的名字即可

#配置tnsnames.ora

[oracle@rhel6 admin]$ vi tnsnames.ora

listener1=(ADDRESS = (PROTOCOL = TCP)(HOST =192.168.56.2 )(PORT = 2521))

#修改LOCAL_LISTINER参数

sys@ORCL>alter system set local_listener=listener1;

System altered.

#查看监听状态

[oracle@rhel6 ~]$ lsnrctl status

另外还可以使用静态监听的方法来修改监听的端口,但是Oracle实例不是“主动”注册到监听器上的。

sys@ORCL>show parameter local_listener

NAME TYPE VALUE

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

local_listener string

#修改监听为静态监听

[oracle@rhel6 admin]$ vi listener.ora

LISTENER=

(DESCRIPTION=

(ADDRESS_LIST=

(ADDRESS=(PROTOCOL=tcp)(HOST=0.0.0.0)(PORT=2521))

(ADDRESS=(PROTOCOL=ipc)(KEY=extproc))))

SID_LIST_LISTENER=

(SID_LIST=

(SID_DESC=

(GLOBAL_DBNAME=orcl)

(ORACLE_HOME=/u02/app/oracle/product/11.2.4/db1)

(SID_NAME=orcl))

#重启监听

[oracle@rhel6 ~]$ lsnrctl stop
