Things to watch out for when implementing DR for OIC

Oracle Integration Cloud (OIC) is a fully managed, highly available integration platform that abstracts much of the underlying infrastructure from customers.

For those who aim for resiliency, implementing disaster recovery (DR) is one approach that protects against cloud region failures. There are two approaches to implementing DR, but that's for a separate blog post. In this post, however, I'd like to outline some of the real challenges and key areas to watch out for when designing and implementing DR for OIC. Even if you opt for the one-click Oracle-Managed DR turnkey solution, you should be aware of these.

There are too many areas that need to be watched out for, from the network setup complexity to managing credentials to understanding how your integrations will behave in the event of a failover. Some others areas of awareness are mentioned below.

Manual Metadata Synchronization
The single biggest responsibility. If your CI/CD process is not robust and disciplined, your primary and secondary instances will drift, and your DR plan will fail.

Loss of In-Flight Data
There is no built-in mechanism to recover transactions that were actively processing during an outage.

Runtime vs. Design-Time URL
The custom endpoint is for runtime traffic only. Developers and administrators must still use the region-specific URL to access the OIC design console. This can cause confusion if not managed properly.

Post-Failover Cleanup
An emergency failover leaves artifacts running in the original primary region. Manual cleanup and resetting the DR configuration are required before you can fail back, as documented in "Resetting DR Configuration After a Failover".

Component Exclusions
Visual Builder (VB) and Process Automation (OPA) require separate DR handling.

Certificates
SSL certificates must be managed and present in both regions.

OIC provides a robust, enterprise-grade integration platform. The biggest risks when implementing DR are assumptions, drift, and lack of operational rigor.

If you're serious about OIC disaster recovery:

• Automate everything you reasonably can
• Build in recovery, atomicity, and validations in your integrations
• Test annually
• Align business expectations with platform realities
