Proxy Controller High Availability
By Owen Allen-Oracle on Apr 24, 2014
Proxy Controllers manage the bulk of your asset data. In the past, losing a Proxy Controller to a hardware failure meant losing all of that asset data, and the only way to resume management of the assets was to rediscover them using another Proxy Controller.
However, one of the enhancements in Ops Center 12.2 is full support for Proxy Controller High Availability. You can enable auto failover, and if a Proxy Controller goes down, its managed assets will automatically be migrated to another available Proxy Controller. If you're able to get the old Proxy Controller running, you can migrate the assets back, or migrate them to a new Proxy Controller once it's installed. You can migrate an asset to any Proxy Controller that's associated with the asset's network.
Take a look at the Proxy Controller High Availability section of the Administration Guide for more information.
