Test pre exec (Oracle DB Backup)

First time posting here so I will start by saying Hi to everyone

I am having some trouble with a pre exec and post exec script used to shutdown Oracle environments for backup

Does anyone know of anyway to test these scripts without them shutting environments down? Meaning, any commands that can be used to run the test without Oracle shutting down

I am running Data Protector 7

All the clients are running version 7 on HP-UX 11.11 and Oracle 9

Thank you
