Oracle 11g Backup and Recovery

I have installed Oracle in E Drive. *I need to format my O开发者_如何学PythonS located in C Drive.* Now I need to backup whole database so that when installed new OS, oracle database works fine.

You will have to re-install the Oracle database software. The data that forms the database can be backed up/restored using RMAN or manually. I recommend you practice a restore before blowing away your current environment.
