Oracle 遠程訪問配置

服務端配置

如果不想自己寫,可以通過 Net Manager 來配置.

以下配置文件中的 localhost 改為 ip 地址,否則,遠程不能訪問.

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\112040x64 OracleHome true

4.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
