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

)

)

linux操作系统下oracle数据库如何配置监听

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 stop

3. 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 bkserver

TNS Ping Utility for 32-bit Windows: Version 10.2.0.1.0 - Production on 12-8月 -

2010 17:11:04

Copyright (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) (SERVIC

E_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。

有关linux命令监听某个进程怎么写

第一个的话可以用

ps aux | grep abc | grep -v grep

如果返回值为0，那这个进程存在，如果不为0，那就不存在，下一步去启动它。

第二个的话，端口开启什么意思？如果没有socket，或者说一个程序去监听一个端口，那单靠脚本是搞不了的
