sshapiro currious why you are running a database that is about ten years out of support, especially if your DBAs do not want to use the tools native to that version.
Glad you got your problem solved, did not suggest start/end scripts as I understood that you wanted a RMAN like solution which was why I suggested EBU.
How do you handle the archive logs generated by database while it is in backup mode ? Thinking in RMAN scripts you usually do the online backup and a then backup of the archive logs
