Chapter 9. Fail over to the secondary site

A failover from the primary site to the secondary site will happen automatically based on the checks configured in the loadbalancer.

When the primary site loses its state in Data Grid or a network partition occurs that prevents the synchronization, manual procedures are necessary to recover the primary site before it can handle traffic again, see the Switch back to the primary site chapter.

To prevent an automatic fallback to the primary site before those manual steps have been performed, configure the loadbalancer as described following to prevent this from happening automatically.

For a graceful switch to the secondary site, follow the instructions in the Switch over to the secondary site chapter.

See the Multi-site deployments chapter for different operational procedures.

Follow these steps to manually force a failover.
