Oracle RMAN Database Incremental Backup Script

This is the third post/script in this series, the first script was Oracle RMAN Database Full Hot Backup Script

The second script was Oracle RMAN Database Full Cold Backup Script

The following script will incrementally backup the database while it is open (although it may be used while the database is in the mount mode also).
