Before your start creating service instances, decide whether you want to provision all services on a single Oracle Cloud Applications instance or if you want to provision each service on a separate Oracle Cloud Applications instance.
Considerations for Production and Stage Environments
When you select a service or services to be provisioned on an Oracle Cloud Applications instance, a production and a stage environment will be created for you.
Consider the following points while planning your environment.
- If you are provisioning instances for the first time, you'll provision your services on a new Oracle Cloud Applications instance. The brand new instance provides application environments with no application data so that you can setup and configure Oracle Applications afresh. Every new instance that you create will be a standalone and completely independent to any of your existing instances. The entitlements that you have selected will be consumed by the new instance and cannot be transferred to any of your existing instances.
For provisioning any subsequent subscribed services, you can use an existing Oracle Cloud Applications instance or create a new one.
What is the impact of choosing an existing Oracle Cloud Applications instance or creating a new one? When you select an existing Oracle Cloud Applications instance, you add the entitlements to the existing instance that you select. This enables additional functionality to the existing instance immediately or after the next update window depending on the functionality included in the entitlements.
When you create a new Oracle Cloud Applications instance, the new instance will be completely standalone and independent of any existing instances that you have already created. A simple example is that data is stored independently for each instance and data will not be shared between the instances.
Once you submit the request to create an instance, it is an irreversible process. The entitlements that you have selected will be consumed only by the new or existing instance that you have specified and the entitlements cannot be transferred to any other instances.
Considerations for Creating Additional Test Environments
While creating additional test environments take care of the following points:
- Create additional test environments only after creating your production and stage environments.
- The additional test environment is created on a new single Oracle Cloud Applications instance in the data center where you have created your production instance. This ensures that the test environments are separate from your production and stage environments. The additional test instance will be brand new with no application data so you can setup and configure Oracle Applications afresh. You can also schedule production-to-test to bring application data from the production instance to the newly provisioned additional test instance.
