Run RMAN backup from Oracle Scheduler (11g)

Hello,

I have my scheduler configured to run my backup shell script from scheduler, but as one of the requirements for configuring the scheduler we need to set OS attributes with password.

begin

dbms_scheduler.create_credential (

    credential_name     => 'RMAN_Credential',

    username            => 'oracle',

    password            => 'password'

);

end;

Unfortunately for our env, oracle password is encrypted and does not support direct login. How can I bypass the password?

NOTE: we sudo into oracle after logging in as ourselves.
