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_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 true4. 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
