linux下如何用命令来配置oracle11g的监听

这个不是命令配置的，是改文件

如果是服务端：

$ORACLE_HOME/network/ADMIN目录，修改LISTENER.ORA

到$ORACLE_HOME/bin下，通过lnsrctl start启动监听  lnsrctl stop | lnsrctl status 分别是停止监听和查看监听状态

如果是客户端：

$ORACLE_HOME/network/ADMIN目录，修改tnsnames.ora

==========================================================

配置LISTENER.ORA的demo：

LISTENER =                                                                     

 (ADDRESS_LIST=                                                                

(ADDRESS=(PROTOCOL=tcp)(HOST=localhost)(PORT=1521))                          

(ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))                     

                                                                               

SID_LIST_LISTENER=                                                             

  (SID_LIST=                                                                   

(SID_DESC=                                                                   

        #BEQUEATH CONFIG                                                     

         (GLOBAL_DBNAME=salesdb.mycompany)                                     

         (SID_NAME=sid1)                                                         

         (ORACLE_HOME=/private/app/oracle/product/8.0.3)                       

        #PRESPAWN CONFIG                                                     

        (PRESPAWN_MAX=20)                                                      

  (PRESPAWN_LIST=                                                            

          (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))               

        )                                                                      

       )                                                                       

      )                                                                        

配置tnsnames.ora的demo：

ora_xxx =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = TCP)(HOST = xx.xx.xx.xx)(PORT = 1521))

    )

    (CONNECT_DATA =

      (SERVICE_NAME = ora11g)    <-----这个地方填SID_NAME也行

    )

  )

*** 作方法如下：

1.将secureCRT连接到数据库所在的linux机器，然后切换到oracle用户模式下；

2.接下来用sqlplus登录到数据库，然后再关闭数据库；

3.然后起动监听；

4.最后客户端连接。

工具和原料：linux安装，oracle数据库，SecureCRT，任意ssh连接工具都可以。

1. 修改监听器配置文件Linux下Oracle监听器配置文件在：$ ORACLE_HOME/network/admin/listerer.ora, 如： /bank/oracle/oracle10g/product/10.2.0/network/admin/listener.ora 修改并配置要监听SID的相关信息，如：#listener.ora Network Configuration File: /bank/oracle/oracle10g/product/10.2.0/network/admin/listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER = (SID_LIST =(SID_DESC = (SID_NAME = PLSExtProc) (ORACLE_HOME = /bank/oracle/oracle10g/product/10.2.0) (PROGRAM = extproc))(SID_DESC = (GLOBAL DBNAME = bkserver) (SID_NAME = bkserver)) )LISTENER = (DESCRIPTION_LIST =(DESCRIPTION = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) (ADDRESS = (PROTOCOL = TCP)(HOST = 10.7.13.242)(PORT = 1521))) ) 2. 启动监听器(1). 切换至oracle安装用户（一般为oracle）su - oracle (2). 启动监听器lsnrctl start 另：停止监听器lsnrctl stop3. 测试监听器是否运行正常在客户端修改tnsnames.ora配置文件就访问Oracle数据库，如：BKSERVER = (DESCRIPTION =(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.7.13.242)(PORT = 1521)))(CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = BKSERVER)) ) 通过命令tnsping测试是否能访问到监听器，如：M:\>tnsping bkserverTNS Ping Utility for 32-bit Windows: Version 10.2.0.1.0 - Production on 12-8月 -2010 17:11:04Copyright (c) 1997, 2005, Oracle. All rights reserved.已使用的参数文件:D:\oracle\product\10.2.0\client_1\network\admin\sqlnet.ora已使用 TNSNAMES 适配器来解析别名Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.7.13.242)(PORT = 1521))) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = BKSERVER)))OK (20 毫秒)注意： 监听器是否能被tnsping通跟数据库的开启/关闭无关，所以就算可以tnsping通监听器但未必能连接到数据库，这时请检查listener.ora文件配置信息是否正确，还有数据库是否已经被开启。
