Reason :

This error message "ORA-01031: insufficient privileges" means the authentication failure to access the database for backup.

The password file must be the problem, if not the DB username is not removed. The password file might have expired or changed or do not have permissions.

Solution :

Please have your DB team to remove/recreate the password file.

Command would look like the below:

ORAPWD FILE=filename [ENTRIES=numusers] [FORCE={Y|N}] [IGNORECASE={Y|N}] [NOSYSDBA={Y|N}]
