Option Description
Number of active nodes
The maximum number of active Orchestrator server instances in the
cluster.
Active nodes are the Orchestrator server instances that run workflows and
respond to client requests. If an active Orchestrator node stops responding,
it is replaced by one of the inactive Orchestrator server instances.
The default number of active Orchestrator nodes in a cluster is one.
Heartbeat interval (milliseconds)
The time interval, in milliseconds, between two network heartbeats that an
Orchestrator node sends to show that it is running.
The default value is 5000 milliseconds.
Number of failover heartbeats
The number of heartbeats that can be missed before an Orchestrator node
is considered failed.
The default value is 12 heartbeats.
The default failover timeout is 1 minute and is equal to the value of the default heartbeat interval
multiplied by the number of the default failover heartbeats.
5 Log in to the Orchestrator configuration interface of the second Orchestrator server as vmware.
6 Repeat Step 3 and Step 4.
You have set up an Orchestrator cluster.
What to do next
You can add more Orchestrator cluster nodes.
IMPORTANT When you configure Orchestrator to work in cluster mode, you must first start one of the
Orchestrator servers and wait until it starts and initializes the database. A cluster node is considered
running when on the Server Availability tab, the node appears under Started cluster nodes with a Running
status. If you start more than one Orchestrator servers at the same time, concurrency issues occur as all of
the started Orchestrator servers try to initialize the database.
Start the Orchestrator Server
To work with Orchestrator, ensure that the Orchestrator server service has started.
Prerequisites
n
If you installed Orchestrator standalone, verify that your system has at least 2GB of RAM. The
Orchestrator server might not start if your system does not meet this requirement.
n
Verify that all the status indicators display a green circle. You cannot start the Orchestrator server if any
of the components is not configured properly.
Procedure
1 Log in to the Orchestrator configuration interface as vmware.
2 Click Startup Options.
3 If the Orchestrator server has stopped, click Start service.
The Orchestrator server status appears as Service is starting. The first boot can take 5-10 minutes
because the server is installing the Orchestrator plug-ins content in the database tables.
A message states that the service has started successfully.
