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 build an Orchestrator cluster by installing and configuring the main
Orchestrator server instance (Orchestrator server 1) and importing its configuration 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 24.
2 Configure a database instance.
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.
3 Log in to the Orchestrator configuration interface as vmware, and configure Orchestrator server 1 to
work with the database you configured.
See “Configuring the Orchestrator Database Connection,” on page 50.
4 Configure Orchestrator server 1 to work in cluster mode.
See “Configure an Orchestrator Cluster,” on page 64.
5 (Optional) Install and configure additional Orchestrator plug-ins.
6 Click the Reset current version link on the Troubleshooting tab to reinstall previously installed
Orchestrator plug-ins with the newly configured database.
See “Configure the Orchestrator Plug-Ins,” on page 58.
7 Start Orchestrator server 1 and wait until it starts successfully.
8 Export the Orchestrator server 1 configuration.
See “Export the Orchestrator Configuration,” on page 27.
9 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 24.
10 On Orchestrator server 2, install the plug-ins that you have installed on Orchestrator server 1.
11 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 29.
