Starting and Stopping the COS Services

COS consists of four services: Content HostingA COS - SD function used to provide content to student Testing Devices. Content Hosting authenticates content requests, decrypts content, and aggregates items into forms., Content ManagementA COS - SD function used to manage the delivery of test content to each site that needs Content Hosting. Sites can be configured to download only the test content needed to reduce download times and storage space requirements. For example, a site could download test content for only one test administration. Content Management can also be set up to download content to a network shared location that multiple Content Hosting services can access., Relay, and Restricted Proxy.

These services execute in the background, and start automatically after installation and whenever the COS - Service Device (COS - SD) is booted. In addition, administrators can start and stop these services manually. Technology Coordinators should be familiar with the process of starting and stopping these services.

Windows

On a Windows COS - SD, perform the following steps:

  1. Select Control Panel–Administrative Tools–Services.

  2. Select a service—CentralOfficeContentHost, CentralOfficeContentManagement, CentralOfficeRelay, or CentralOfficeRestictedProxy—right-click and select Start (to start) or Stop (to stop) the service.

Mac (OS X and macOS)

On a Mac COS - SD, the COS services execute in the background without a standard graphical window (each service name is prefixed with com.datarecognitioncorp). A Mac administrator uses the launchd and launchctl commands in the terminal to manage these services.

service centralofficecontenthosting start

service centralofficemanagement start

service centralofficerelay start

service centralofficerestrictedproxy start
