Cloning the virtual machine on which the main Orchestrator server instance is configured. In this case,
if the Orchestrator nodes are behind a load balancer configured in the vSphere Web Client, one of the
Orchestrator nodes might appear in the inventory along with the load balancer. You can remove it by
using the the Managed Object Browser (MOB) of the corresponding vCenter Server.
NOTE All Orchestrator server nodes of a cluster must have identical server and plug-ins' configuration and
contents. If you want to make changes on the Orchestrator content, for example to edit a workflow or an
action, you must stop all Orchestrator server nodes except one and cancel all running tasks that refer to the
content you want to change. You can then make changes to the only server node that is active, and restart
the other Orchestrator server instances in the cluster.
The following use case describes how to configure an Orchestrator cluster by exporting the configuration of
the main Orchestrator server instance (Orchestrator server 1) and importing it to a newly installed
Orchestrator server instance (Orchestrator server 2).
1 Install Orchestrator server 1 or download and deploy the Orchestrator Appliance.
For information about installing Orchestrator standalone, see “Install Orchestrator Standalone,” on
page 22. For information about downloading and deploying the Orchestrator Appliance, see
“Download and Deploy the Orchestrator Appliance,” on page 25.
2 Configure a database instance and configure Orchestrator server 1 to work with that database.
IMPORTANT Configure the database to accept multiple connections so that it can accept connections
from the different Orchestrator instances. To prevent possible transactional deadlocks when the
database is Microsoft SQL Server database, you must set the ALLOW_SNAPSHOT_ISOLATION and
READ_COMMITTED_SNAPSHOT database options to on.
See “Configuring the Orchestrator Database Connection,” on page 50.
3 Log in to the Orchestrator configuration interface as vmware, and configure Orchestrator server 1 to
work in cluster mode.
See “Configure an Orchestrator Cluster,” on page 64.
4 (Optional) Configure and install Orchestrator plug-ins.
See “Configure the Default Plug-Ins,” on page 58.
5 Export the Orchestrator server 1 configuration.
See “Export the Orchestrator Configuration,” on page 30.
6 Install Orchestrator server 2 or download and deploy the Orchestrator Appliance.
For information about installing Orchestrator standalone, see “Install Orchestrator Standalone,” on
page 22. For information about downloading and deploying the Orchestrator Appliance, see
“Download and Deploy the Orchestrator Appliance,” on page 25.
7 Import the Orchestrator configuration of Orchestrator server 1 to Orchestrator server 2.
By importing the Orchestrator configuration, you make both configurations identical. For more
information about importing the Orchestrator configuration, see “Import the Orchestrator
Configuration,” on page 32.
8 Log in to the Orchestrator configuration interfaces of both Orchestrator server instances as vmware, and
verify that both configurations are identical.
9 On the vCenter Server tab of the Orchestrator configuration interface of Orchestrator server 2, type the
credentials that Orchestrator server 2 must use to establish the connection to the vCenter Server
instance.
