Please be sure that you have your Users configured correctly. From the Oracle integration Guide:
Configuring Oracle user accounts
Decide under which user accounts you want backups to run. Data Protector requires the following
user accounts:
•
Oracle operating system user account
For details, see
“Configuring Oracle operating system user accounts” (page 24).
•
Oracle database user accounts
For details, see
“Configuring Oracle database users accounts” (page 25).
Configuring Oracle operating system user accounts
For each Oracle database, Data Protector requires an operating system user account that has
Oracle rights to back up the database. This user account usually belongs to the
DBA user group
(OSDBA user). The user account under which the Oracle database is running has these rights. For
example, to find such a user on UNIX systems, run:
ps -ef|grep ora_pmon_
DB_NAME
or
ps -ef|grep ora_lgwr_
DB_NAME
