1. There are six instances.
2. Server Pool prod has a maximum of four servers.
3. CRM is a policy managed, uniform service using Server Pool prod.
4. ERP is a policy managed, singleton service using Server Pool prod.
5. Grid infrastructure is installed and running in its default configuration.

• A.High availability for the ERP service
• B.Load balancing of connection requests for ERP across all database instances running on servers in the prod pool
• C.Load balancing of client connection requests for CRM across four Single Client Access Name (SCAN) listeners
• D.Load balancing of connection requests across all six database instances
• E.Load balancing of client connection requests for ERP across three Single Client Access Name (SCAN) listeners
• F.High availability for the CRM service
• G.Load balancing of connection requests for CRM across all database instances running on servers in the prod pool
