Oracle RMAN Database Full Hot Backup Script

I was asked by one of my customers to develop some rman backup/restore scripts.

These scripts are a modified versions from some old scripts developed by me + some enhancement from other similar scripts .

Following is the first script in the series, it to fully backup the database while it is open.
— {Please fully test these scripts before using them in your specific environment} —
