Clustered Ops Center installation

Today's question from an Ops Center user:

"Can we cluster Ops Center deployments using, say, Solaris Cluster? How would we do it?"

Well, there are a couple of possible ways that you can install the Enterprise Controller so that it can fail over.

The first method is to use the documented HA installation, which uses Oracle Clusterware, two or more Enterprise Controller systems, and a remote customer-managed database. The procedures for this kind of installation are documented in the Oracle Solaris and Linux install guides.

The second is to install the Enterprise Controller in an LDom controlled by Oracle Solaris Cluster, and then have the Enterprise Controller fail over between hosts via Cluster. You can use an embedded database or a remote database with this solution.

Proxy Controller High Availability

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.
