oracle 客户端连接

使用SI OBJECT 或者TOAD 为了方便连接不同地址的数据库，可以修改下面的这个文件： D:\oracle\product\10.1.0\db_1\NETWORK\ADMIN 修改如下： ORCL199 = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.19.199)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) ) ) ORCL99= (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.19.99)(PORT = 1521)) ) (CONNECT_DATA = (SERVICE_NAME = orcl) ) )
