Common

As of the 23.12 release, net new OIC customers, i.e. those that do not currently subscribe to OIC Gen2 instances, will only be able to provision OIC3 instances. 

Integration

A new Notifications Center in Oracle Integration provides information about asynchronous, design-time events, such as project import, etc.

Note the megaphone icon to the left of the bell, which is for announcements. Announcements were previously visible through the bell icon.

Import and Export between Oracle Integration Instances

This Oracle Integration Generation 2 feature is now available in Oracle Integration 3. This feature enables you to perform a mass export and import of your Oracle Integration design-time artifacts.

Note the new Storage menu option above. You specify details here about the OCI Object Storage bucket to be used in the new Import and Export menu option.

Oracle Integration Project Enhancements

Oracle Integration developers can now copy an integration into a project from the Add integration panel. 
The integration can be either in a different project or outside of any project (that is, globally available).

With release 23.12, you can also include up to 100 integrations in a project. See the service limits documentation for details about this and other limits.

Publish REST-based Integrations to OCI API Gateway

This feature is now available within Oracle Integration projects. Activated integrations can be published to OCI API Gateway.

This is more than parity, in respect to Oracle Integration Generation 2. In Generation 2, each publishing to the OIC API Gateway created a new deployment. OCI API Gateway allowed for 20 deployments per gateway, which was rather limiting. However, each gateway can provide for 50 routes. That is, one gateway instance can protect up to 1000 APIs. The 23.12 release makes use of this feature, allowing you to select an existing deployment. If you do this, a new route is created in that deployment. Otherwise, you can create a new deployment.

B2B
