ORACLE 简易客户端配置
1、从 ORACLE 下载客户端的简易包，加压缩到磁盘上的任意目录，例如 E:\Utility\Oracle\Win32
2、将该路径增加到系统环境变量 PATH 中，然后将下面的注册表文件导入到注册表中
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE]
"NLS_LANG"="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
"TNS_ADMIN"="E:\\Utility\\Oracle"
[HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE]
"NLS_LANG"="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
"TNS_ADMIN"="E:\\Utility\\Oracle"
[HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\ORACLE]
"NLS_LANG"="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
"TNS_ADMIN"="E:\\Utility\\Oracle"
[HKEY_LOCAL_MACHINE\SOFTWARE\ORACLE]
"NLS_LANG"="SIMPLIFIED CHINESE_CHINA.ZHS16GBK"
"TNS_ADMIN"="E:\\Utility\\Oracle"
3、在 E:\Utility\Oracle 目录下增加 tnsnames.ora 文件，文件内容如下所示：
DB_CENTER =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = DB_SERVER)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = DB_CENTER)
)
)
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = DB_SERVER)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = DB_CENTER)
)
)
4、使用 P/L SQL Developer 工具即可正常访问
