怎么在 Oracle 中配置遠程訪問？相信很多沒有經驗的人對此束手無策，為此本文總結了問題出現的原因和解決方法，通過這篇文章希望你能解決這個問題。
1. 網絡監聽配置
# 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多個 IP 時, 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))多個 IP 時, 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. 停止和啟動服務
先停止以下服務, 然后再啟動.
OracleOraDb11g_homeTNSListener
OracleService*客戶端配置
1. 下載 ODAC 壓縮包.
2. 解壓下載的 ODAC 壓縮包.
3. 執行安裝命令
示例:
install.bat all D:\Program\ODAC\12040x64 OracleHome true4. 添加環境變量
ORACLE_HOME : 是 ODAC 安裝的目錄.
TNS_ADMIN : 是文件 tnsnames.ora 所在的目錄, 一般為 ODAC 安裝目錄下的 network\admin 中.
注: TNS_ADMIN 可以不用添加, 直接將 tnsnames.ora 文件復制到 ODAC 安裝目錄下即可
將 %ORACLE_HOME% 添加到 PATH 環境變量中.
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)
)
)說明:
db-host : 數據庫電腦的 IP 或者是計算機名
db-name : 數據庫 TNS 配置的名稱
