How do I make a backup (logical backup) of Oracle without a third-party tool?
Previously in this article http://blog.csdn.net/great_domino/archive/2005/01/18/257414.aspx point to a little, but not detailed said!
Now the way to tell you, of course, for those beginners!
First create a batch file Databack.bat text see content as long as 2 lines, as follows

@echo off
Start Exp Domino/great_domino@domino full=y file=d:\back\last.dmp

Specific format, can check http://blog.csdn.net/great_domino/archive/2005/01/18/257414.aspx
Then do a Windows planning task, scheduled to execute Databack.bat files, used Windows should be done planning tasks, in the Control Panel, if you add a plan can not start, that 80%, the service did not start, check the menu above, select Advanced, start service, if you can not start , what to do, that 90% is the service is banned, go to Internet Manager to start the Task Scheduler service program in the service! Ok!
When do you want to back up?

By the way, a scheduled backup is necessary, do not know when the database crashes or destroyed by others, do not lazy people to do the program, and if you do not plan the task of the user, it is best to disable Task Scheduler, this is a dangerous Windows vulnerability
