The ATG product suite contains several components that must be unique within an ATG server cluster. If you enable and start up more than one instance of these components, errors can result. These unique components are:
Fulfillment Module used by ATG Commerce
Process Editor Server used by the Scenario Manager
Fulfillment Module
Only one instance of the ATG Commerce Fulfillment module should run on the system. Only one ATG server instance should be started with the command startDynamoOnJBOSS -m Fulfillment. To learn more about the Fulfillment module, see the ATG Commerce Programming Guide.
Process Editor Server
A cluster of ATG servers should only contain one process editor server. Make sure you have one process editor server configured and that all other ATG instances are aware of it. See the ATG Personalization Programming Guide information about setting up scenario servers.
Because running the global scenario server places an additional burden on your ATG server, this instance should not serve any pages.
Workflow Process Manager
A cluster of ATG servers should always contain exactly one workflow process manager. Make sure only one workflow process manager is configured and that all other ATG instances are aware of it. See the ATG Personalization Programming Guide information about setting up a workflow process manager.
