Ondemand content masters (OCM) download content for managed device distribution from content distribution networks (CDN). Only primary servers can be OCMs. Satellite servers can function as ondemand content servers for content replication purposes, but they cannot download content from a CDN. There must always be at least one primary server designated as OCM.
OCMs require an Internet connection to communicate with and download content from the CDN. If the OCM requires a proxy to access the CDN, the OCM server’s Subscription proxy configuration file is used.
To designate a primary server as an OCM:
Navigate to Configuration > Server Hierarchy, select the primary server in the Server Hierarchy panel, and select Set as Ondemand Content Master in the Action drop-down menu.
To remove the OCM designation from a primary server:
Navigate to Configuration > Server Hierarchy, select the primary server in the Server Hierarchy panel, and select Remove as Ondemand Content Master in the Action drop-down menu.
