修改Oracle默认监听端口

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

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>altersystemsetlocal_listener="(address=(protocol=tcp)(host=rhel6)(port=2521))";

Systemaltered.
#查看监听状态
[oracle@rhel6~]$lsnrctlstatus

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:~]$sqlpluszx/zx@192.168.56.2:2521/orcl

SQL*Plus:Release12.1.0.1.0Productionon星期六1月720:24:172017

Copyright(c)1982,Oracle.Allrightsreserved.


连接到:
OracleDatabase11gEnterpriseEditionRelease11.2.0.4.0-64bitProduction
WiththePartitioning,OLAP,DataMiningandRealApplicationTestingoptions

SQL>

修改监听端口完成。

4、把Oracle实例的注册端口改回1521

sys@ORCL>altersystemsetlocal_listener='';

Systemaltered.

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@rhel6admin]$vitnsnames.ora
listener1=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.56.2)(PORT=2521))
#修改LOCAL_LISTINER参数
sys@ORCL>altersystemsetlocal_listener=listener1;

Systemaltered.
#查看监听状态
[oracle@rhel6~]$lsnrctlstatus

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>showparameterlocal_listener

NAME				TYPE			VALUE
---------------------------------------------------------------------------------------------------
local_listener			string
#修改监听为静态监听
[oracle@rhel6admin]$vilistener.ora
LISTENER=
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=tcp)(HOST=0.0.0.0)(PORT=2521))
(ADDRESS=(PROTOCOL=ipc)(KEY=extproc))))
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=orcl)
(ORACLE_HOME=/u02/app/oracle/product/11.2.4/db1)
(SID_NAME=orcl))
#重启监听
[oracle@rhel6~]$lsnrctlstop

静态监听实例的状态为UNKNOWN，测试连接成功
