Oracle中登录文件Login的定制
????? 在window系统针对Oracle登录调试设置登录会话的各种信息,从而定制login.sql.
在默认的情况下Oracle的默认登录执行的sql目录在login.sql所在目录
(D:\app\Administrator\product\11.1.0\db_1\sqlplus\admin)然后根据Kyte写
的login文件，修改一点符合自己的需要。
? 但是在有时候修改次文件不起作用,可能是Oracle中登录执行路径问题.
检查如下:
1.在运行"regedit"
2.选择KEY_LOCAL_MACHINE中的SOFTWARE,选中其下的Oracle目录中的Key_oradb11g_home1,
在右边的显示栏中显示各种信息.检查SQLPATH是否为你存放登录SQL所在的目录,如果不是修改即可.

? 你会发现在windows下调用vi不正常,可以修改一下定义：
? define _editor=C:\Program Files\Notepad++\notepad++.exe
? 备注:我采用的notepad++,你也可以定义为记事本.
