OMS needed for backups?

[fortage]

Oracle 9.2.
Currently running Manager in Standalone mode and whenever I try to schedule or run a backup it indicates that the wizard can only be launched when connected to the OMS. This is my only Oracle install so I attempted to run the Enterprise Manager Configuration Assistant but received the following error.
"Template Transaction_Processing.dbc soes not exist. Please spcify an existing template for database creation."
"SQL execpion OS Authentication for database connections is not permitted please specify a username and password"

Can I schedule backups without being in OMS? Or how can I get passed the error?

Thanks

RMAN is the tool which is usually used for backups.
It's a commandline-tool so you can write a script and have your os-scheduler call it (I guess you have no third party backup-solution at hand, which usually work with RMAN scripts too).
Search this forum for rman, I think there should be some sample scripts somewhere, that might give you an idea how to start.
