  • An identity domain that was created in another region and has been replicated to the current region. See Replicating an Identity Domain to Multiple Regions.
• To create an Oracle Integration instance, you must be a tenancy administrator or have been granted the permissions required to create Oracle Integration instances. See Manage Access and Assign Roles.
• You can no longer create a new Oracle Integration Generation 2 instance.
