Oracle Rman Backups From

Oracle rman backups from Windows Script Oracle Tips by Burleson Consulting

Scheduling tasks such as an Oracle rman backup can be challenging in a Windows environment without a thirdparty approach such as SFU, 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 rman backup Once tested, the bat file is invoked with the Windows AT scheduling command. For working examples of Oracle rman backups in Windows scripts, Jeff Hunter, author of "Conducting the Java Job Interview" has a great script to schedule an rman backup in a Windows environment. Lets examine Hunter's rman backup 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. rman target %DB_USERNAME%/%DB_PASSWORD%@%TNS_ALIAS%

Above, note that this is all on one line, an important consideration when doping DOS bat file scripting. Here is Jeff's code: REM +--------------------------------------------------------------------------+ REM | VALIDATE COMMAND-LINE PARAMETERS | REM +--------------------------------------------------------------------------+ if (%1)==() goto USAGE if (%2)==() goto USAGE if (%3)==() goto USAGE REM +--------------------------------------------------------------------------+ REM | VALIDATE ENVIRONMENT VARIABLES | REM +--------------------------------------------------------------------------+ REM REM
