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

# 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_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:

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 = <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
