Deregister1Disconnects the secondary instance from the primary instance. Stops the secondary instance from
receiving configuration updates from the primary instance. Deregistration restarts the deregistered
node.
When full replication is in progress on an instance, do not attempt to deregister that instance. Wait
until the full replication is complete and the secondary instance is restarted before you deregister
the secondary instance.
Promote Requests to promote a secondary instance to the primary instance. All updates to the current
primary instance are stopped so that all replication updates can complete. The secondary instance
gets primary control of the configuration when the replication updates complete.
The secondary instance must be active before you can promote it to the primary instance.
Full Replication Replicates the primary instance’s database configuration for the secondary instance. ACS is
restarted.
When full replication is in progress on an instance, do not attempt to deregister that instance. Wait
until the full replication is complete and the secondary instance is restarted before you deregister
the secondary instance.
Backup Select the secondary instance that you want to back up and click this button to take a backup. See
Backing Up Primary and Secondary Instances, page 17-7 for more information.
