Generating Viewables and Thumbnails in Clustered Environments
All publishing and thumbnail conversion is processed using background queues. In a cluster, only one Windchill server processes the queue, using a dedicated MethodServer called the Background MethodServer. As a result, in a clustered environment, all viewable generation is done through the Background MethodServer.
By default, the Thumbnail Generator is executed by the worker on the worker machine, before the viewables are retrieved (along with the thumbnail) by the Worker Agent. However, if this is disabled, and unless you are using remote thumbnail generation, the thumbnail generation is also done from the Background MethodServer, as the Worker Agent runs on the method server that is processing queues.

As of Windchill 10.2, the Thumbnail Generator is no longer supported on UNIX; server-side thumbnail generation is only supported on Windows platforms. For UNIX platforms, server-side Thumbnail Generation must be performed with the “By CADAgent” configuration. This is achieved by setting the thumbnail.usecadagent property to true in wvs.properties and creating a remote Thumbnail Generator (Worker) of type THUMBNAIL on a Windows machine.
