修改oracle监听端口

修改端口号的整体步骤：
1.1 查看当前监听的状态
1.2   停止监听
1.3   修改监听文件的端口号
1.4   修改初始化参数local_listener
1.5   重启监听器
1.6   修改完毕，使用新端口登录测试

实践步骤：

1.1 查看当前监听的状态

[test@ASI-1 ~]$lsnrctl status

1.2 停止监听

[test@ASI-1~]$lsnrctl stop

LSNRCTL for Linux: Version 10.2.0.1.0 - Production on 11-MAR-2011 16:36:49

Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.0.100)(PORT=1521)))

The command completed successfully

1.3修改监听文件的端口号

把端口号修改为1530，分别修改listener.ora和tnsname.ora文件

[test@ASI-1 ~]$ cd/usr/opt/oracle/product/10.2.0/db_1/network/admin/

[test@ASI-1 admin]$ pwd

/usr/opt/oracle/product/10.2.0/db_1/network/admin

[test@ASI-1~]$vi listener.ora

# listener.ora Network Configuration File: /usr/opt/oracle/product/10.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /usr/opt/oracle/product/10.2.0/db_1)

(PROGRAM = extproc)

)

(SID_DESC =

(GLOBAL_DBNAME = orcl)

(ORACLE_HOME = /usr/opt/oracle/product/10.2.0/db_1)

(SID_NAME = orcl)

)

LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.100)(PORT = 1530))

)

[test@ASI-1~]$vi tnsnames.ora

# Generated by Oracle configuration tools.

ORCL =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.100)(PORT = 1530))

)

(CONNECT_DATA =

(SERVICE_NAME = orcl)

)

EXTPROC_CONNECTION_DATA =

(DESCRIPTION =

(ADDRESS_LIST =

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

)

(CONNECT_DATA =

(SID = PLSExtProc)

(PRESENTATION = RO)

)

1.4 修改初始化参数local_listener

[test@ASI-1~]$sqlplus / as sysdba

SQL*Plus:Release 10.2.0.1.0 - Production on 星期六 7月 19 13:24:02 2008

连接到:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production
With the Partitioning, OLAP and Data Mining options

SQL> showparameter local_listener

NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (address=(protocol=tcp)(host=s
kate)(port=1522))
SQL> alter system setlocal_listener="(address=(protocol=tcp)(host=192.168.0.100)(port=1530))";

系统已更改。

1.5 重启监听器

[test@ASI-1~]$lsnrctl start
