Backup Oracle database

Hi all,

I'm trying to do a backup from Oracle database but I'm receiving the message: "Access is denied to Remote Agent". But when I try to backup files from the same server it works.

So, why the connection with Remote Agent don't work when I configure backup from Oracle and work when I configure backup from files?

I'm using:

Backup Exec 2012 sp4

Windows Server 2008 64 bits

Oracle 11.2.0.4

Thanks
