Configuration Use Cases and
Troubleshooting 10
You can configure the Orchestrator server to work with the vCenter Server appliance, you can also uninstall
plug-ins from Orchestrator, or change the self-signed certificates.
The configuration use cases provide task flows that you can perform to meet specific configuration
requirements of your Orchestrator server system, as well as troubleshooting topics to understand and solve
a problem, if a workaround exists.

Configuring a Cluster of Orchestrator Server Instances
To increase the availability of Orchestrator, you can configure a cluster of Orchestrator server instances. In
the cluster, multiple Orchestrator server instances (Orchestrator server nodes) work together. To achieve
this, the nodes must share one database and have identical configuration of the Orchestrator server and
plug-ins.
The active Orchestrator server nodes respond to client requests and run workflows. If an active Orchestrator
server node fails to send heartbeats to indicate it is up and running, it is considered as non-responsive and
an inactive Orchestrator node becomes active to take control and resume all of the workflows from the point
they were interrupted.
After you configure an Orchestrator server instance in cluster mode, you can create the rest of the
Orchestrator cluster nodes by one of the following methods:

Exporting the configuration of the main Orchestrator server instance and importing it to the newly
installed Orchestrator server instances.
