Installing the Laserfiche Distributed Computing Cluster Service

Distributed Computing Cluster uses a group of machines to perform work for Laserfiche applications. Before it can be used, the Distributed Computing Cluster service must be installed as a Scheduler on one machine. For multi-node clusters, Distributed Computing Cluster must be installed as a Scheduler on one machine and as a Worker on one or more other machines.

Important: Distributed Computing Cluster is performing OCR jobs, images are downloaded to the following directory on the DCCWorker machines: C:\ProgramData\Laserfiche\Distributed Computing Cluster\Temp. Although DCC cleans these files up, Administrators should be aware of this and apply security to these folders if necessary.
