Create Groups for Oracle Integration Access
As a best practice, you should assign permissions to groups rather than to individual users. For this reason, you'll want to create groups for your Oracle Integration users. Then you can grant the groups Oracle Integration access by assigning them service roles.
Group Suggestions
You might want to create groups based on roles in your organization or based on what the members have permission to do. For example, you might create a group called OICDevelopers for users who will be given the ServiceDeveloper role; and another group called OICAdministrators for users who will be given the ServiceAdministrator role.
How to Create a Group
In the Oracle Cloud Console, on the Domains page, open your domain, and click the User management tab. See Creating a Group in the Oracle Cloud Infrastructure documentation.
