Oracle exports from  Windows Scripts

Oracle Database Tips by Donald Burleson

Scheduling tasks such as Oracle export backups can be challenging in a Windows environment without a third-party approach such as JavaScript or Visual Basic.  It's tricky, but you can write old-fashioned DOS bat files, a string of DOS prompt commands, to create an execute an Oracle export on Windows.

Once tested, the bat file is invoked with the Windows AT scheduling command.

 For working examples of Oracle exports in Windows scripts, Jeff Hunter, author of "Conducting the Java Job Interview" has a working export_backup_online_full_9i.bat DOS command script to invoke the Oracle export (the exp command):

Lets examine Hunter's export___.bat Oracle Windows script.  Note that he builds the exp parfile arguments into a DOS variable called %PARFILE%, just like you can invoke Oracle directly from the DOS prompt: e.g.     c:> exp=%PARFILE%:
