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_homeTNSListenerOracleService*

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 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>) ) )
