You must configure Run As account credentials that are used to perform data protection operations on Oracle databases.
If you set up Run As credentials for individual resource groups and the user name does not have full admin privileges, the user name must at least have resource group and backup privileges.
If you have enabled an Oracle database authentication, a red lock icon is shown in the resources view. You must configure database Run As credentials to be able to protect the database or add it to the resource group to perform data protection operations.
