怎么在Oracle中配置远程访问

怎么在Oracle中配置远程访问？相信很多没有经验的人对此束手无策，为此本文总结了问题出现的原因和解决方法，通过这篇文章希望你能解决这个问题。

1.网络监听配置

# listener.ora Network Configuration File: C:\app\Administrator\product\11.2.0\dbhome_1\network\admin\listener.ora# Generated by Oracle configuration tools.SID_LIST_LISTENER = (SID_LIST = (SID_DESC =  (SID_NAME = CLRExtProc)  (ORACLE_HOME = C:\app\Administrator\product\11.2.0\dbhome_1)  (PROGRAM = extproc)  (ENVS = "EXTPROC_DLLS=ONLY:C:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll") ) )LISTENER = (DESCRIPTION_LIST = (DESCRIPTION =  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))  (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) ) )ADR_BASE_LISTENER = C:\app\Administrator

多个IP时,如下:

LISTENER = (DESCRIPTION_LIST = (DESCRIPTION =  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) (DESCRIPTION =  (ADDRESS = (PROTOCOL = TCP)(HOST = 172.24.226.2)(PORT = 1521)) ) (DESCRIPTION =  (ADDRESS = (PROTOCOL = TCP)(HOST = 172.24.226.3)(PORT = 1521)) ) )

2.TNS 配置

# tnsnames.ora Network Configuration File: C:\app\Administrator\product\11.2.0\dbhome_1\network\admin\tnsnames.ora# Generated by Oracle configuration tools.ORCL= (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) (CONNECT_DATA =  (SERVER = DEDICATED)  (SERVICE_NAME = orcl) ) )ORACLR_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST =  (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) (CONNECT_DATA =  (SID = CLRExtProc)  (PRESENTATION = RO) ) )LISTENER_ORCL = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))

多个IP时,如下:

ORCL = (DESCRIPTION = (ADDRESS_LIST =  (ADDRESS = (PROTOCOL = TCP)(HOST = 172.24.226.2)(PORT = 1521))  (ADDRESS = (PROTOCOL = TCP)(HOST = 172.24.226.3)(PORT = 1521)) ) (SOURCE_ROUTE = yes) (CONNECT_DATA =  (SERVER = DEDICATED)  (SERVICE_NAME = orcl) ) )

3.停止和启动服务

先停止以下服务,然后再启动.

OracleOraDb11g_homeTNSListenerOracleService*

客户端配置

1.下载 ODAC 压缩包.

2.解压下载的 ODAC 压缩包.

3.执行安装命令

示例:

install.bat all D:\Program\ODAC\12040x64 OracleHome true

4.添加环境变量

ORACLE_HOME : 是 ODAC 安装的目录.

TNS_ADMIN : 是文件 tnsnames.ora 所在的目录,一般为 ODAC 安装目录下的 network\admin 中.

注: TNS_ADMIN 可以不用添加,直接将 tnsnames.ora 文件复制到 ODAC 安装目录下即可

将 %ORACLE_HOME% 添加到 PATH 环境变量中.

5.配置 TNS

在配置文件 tnsnames.ora 中加入

DBORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = )(PORT = 1521)) (CONNECT_DATA =  (SERVER = DEDICATED)  (SERVICE_NAME = ) ) )

说明:

: 数据库电脑的IP或者是计算机名
: 数据库TNS配置的名称
