Oracle Integration Cloud Gen2, launched in 2019, has established itself as a reliable and sophisticated integration solution for Oracle customers. Following this, Oracle Integration 3 was introduced in 2022, featuring a fully cloud-native architecture that enhances performance, scalability, and user experience. It is specifically engineered to manage more intricate workflows and accommodate elevated integration volumes.

The time has come where you really must take action to upgrade your Oracle Integration instances to avoid service disruption.

FAQs

What is Oracle Integration 3?

Oracle Integration 3 is a cloud-native, microservice architecture-based version of Oracle Integration. It delivers improved performance and reliability, as well as significant improvements in provisioning and other lifecycle management activities by more deeply leveraging the power of Oracle Cloud Infrastructure.

Can I choose the date and time for the upgrade?

Yes. You select the date and time for a 60-minute downtime. Oracle completes the upgrade work on your behalf during the downtime.

Can I change my upgrade window?

Yes. You can change your upgrade window up to 3 days before your selected date and time.

How will the upgrade affect my service?

The upgrade is a planned maintenance event that includes scheduled downtime during the upgrade process. Additionally, your service will be affected in the following ways:

1. Activity stream data isn’t moved to Oracle Integration 3. 
2. When the downtime begins as part of the upgrade, Oracle Integration stops accepting incoming requests for actively running synchronous application-driven orchestrated integrations.
