Execute Failover Tasks

Learn how to manually switch to the DR environment.

To switch from your primary instance to the standby instance during outages:

1. Stop the primary Oracle Integration instance from the Oracle Cloud Infrastructure Console.
2. Prepare your secondary instance.
   1. If you are not using CICD, then ensure that the standby (secondary) instance contains the latest versions of integrations. You can use the import API to import the latest snapshot extracted.
   2. Activate all relevant integrations.
   3. Update the scheduled parameters with the latest values to avoid reprocessing of old data.
3. Update the DNS record at your DNS provider or in the OCI DNS zone to route the traffic to the standby instance.

After the failover process, the standby instance becomes your primary instance, and the instance previously designated as primary becomes the new standby instance.

Note:

• If your original primary instance restarts itself after the failover process, deactivate or shut down scheduled and polling-based integrations.
• If there are backlogs (of asynchronous transactions) in the original primary instance, these may be triggered when the instance restarts, resulting in duplicate transactions. The backlogs belong to the faulted instances of integrations. You can choose how you handle them.
