先从Oracle网站下载Oracle Instant Client压缩包,如果Toad依赖的是32位的,请下载32位版本。
https://www.oracle.com/cn/database/technologies/winsoft/instant-client-download.html
完成后解压到你的目录,开始配置用户环境
变量名:ORACLE_HOME 变量值:C:\Users\jilili\Desktop\Apps\instantclient_11_2 变量名:TNS_ADMIN 变量值:C:\Users\jilili\Desktop\Apps\instantclient_11_2\network\admin 变量名:NLS_LANG 变量值:SIMPLIFIED CHINESE_CHINA.ZHS16GBK 修改PATH变量,在后面添加 C:\Users\jilili\Desktop\Apps\instantclient_11_2
在Oracle Instant Client目录建立tnsname.ora文件
orcl = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.20.111)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) )
完成后打开Toad,就可以进行了。
