Oracle 远程访问配置

服务端配置

如果不想自己写,可以通过 Net Manager 来配置.

以下配置文件中的 localhost 改为 ip 地址,否则,远程不能访问.

1.网络监听配置

Copy Highlighter-hljs code-theme-dark
# 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:

Copy Highlighter-hljs code-theme-dark
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

Copy Highlighter-hljs code-theme-dark
# 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:

Copy Highlighter-hljs code-theme-dark
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_homeTNSListener
• OracleService*

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:

Copy Highlighter-hljs code-theme-dark
install.bat all D:\Program\ODAC\112040x64 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

Copy Highlighter-hljs code-theme-dark
DBORCL =  (DESCRIPTION =    (ADDRESS = (PROTOCOL = TCP)(HOST = <db-host>)(PORT = 1521))    (CONNECT_DATA =      (SERVER = DEDICATED)      (SERVICE_NAME = <db-name>)    )  )

说明:

• <db-host> : 数据库电脑的IP或者是计算机名
• <db-name> : 数据库TNS配置的名称
