Configure Document Conversions Load Balancer and Launcher Services (SharePoint Server 2010)

 

Applies to: SharePoint Server 2010

Topic Last Modified: 2011-09-23

This article explains how to configure the Document Conversions Launcher Service and the Document Conversions Load Balancer for Microsoft SharePoint Server 2010.

Procedures in this task:

In SharePoint Server 2010 an administrator can install applications on the server that enable users to convert documents from one format to another. SharePoint Server 2010 includes two services to support document conversion:

  • Document Conversions Launcher Service launches the document conversions on an application server

  • Document Conversions Load Balancer Service manages the availability of document converters

By default, these services are not automatically enabled when SharePoint Server 2010 is installed. Both services must be enabled for document conversions to work. You can configure the Document Conversions Launcher Service and the Document Conversions Load Balancer Service on a stand-alone server or on one or more servers in a farm. For example, you may have one server running both a Load Balancer and a Launcher service, or you may have one server running a Load Balancer service, and one or more servers running the Launcher service. However, a single instance of a Launcher service can only be associated with a single Load Balancer service. If the Load Balancer service stops, or if the server hosting the service goes down, the corresponding Launcher service will not receive any requests to perform document conversions.

importantImportant
  • Turning off the Document Conversions Load Balancer Service stops the document conversion process and turns off the Document Conversions Launcher Service. To resume the document conversion process, you must restart the Document Conversions Load Balancer Service and the Document Conversions Launcher Service, in that sequence.

  • The Document Conversions Load Balancer Service and the Document Conversions Launcher Service are often run on application servers, not front-end Web servers. Wherever they are run, the services must be configured to communicate with the front-end Web servers, as described in this article.

You can use Central Administration to enable the Document Conversions Launcher or Load Balancer services.

To enable the Document Conversions Launcher or Load Balancer services using Central Administration
  1. Verify that you have the following administrative credentials: you must be a member of the Farm Administrators group on the computer running the SharePoint Central Administration Web site.

  2. In Central Administration, on the Home page, in the System Settings section, click Manage services on server.

  3. On the Services on Server page, in the Action column, click Start for either the Document Conversions Launcher Service or the Document Conversions Load Balancer Service.

    noteNote
    You must configure and start the Document Conversions Load Balancer service before you can configure the Document Conversions Launcher service.
  4. If you click Document Conversions Load Balancer Service, the Load Balancer service is started.

  5. If you click Document Conversions Launcher Service, the Launcher Service Settings page is displayed.

  6. In the Select Server section, verify that the server you want is selected. If it is not selected, on the Server menu, click Change Server. Next, on the Select Server page, click the Name of the server for which you want to configure document conversion settings.

  7. In the Load Balancer section, select the load balancer server to use with the launcher. This is the name of the server on which you configured the Document Conversions Load Balancer Service (see previous procedure.)

  8. In the Port Number section, type the port number that you want the launcher to use for communication. Enter a port number that is not used by other services on the server, but that is open in the firewall on the server.

    noteNote
    If the Document Conversions Load Balancer Service and the Document Conversions Launcher Service are on the same server, the port numbers used for each service must be different.
  9. Click OK. The Launcher service is started.

You can use Central Administration to configure the Document Conversions Launcher Service.

noteNote
You must configure and start the Document Conversions Load Balancer service before you can configure the Document Conversions Launcher service.

  5. In the Load Balancer section, select the load balancer server to use with the launcher. This is the name of the server on which you configured the Document Conversions Load Balancer Service (see previous procedure.)

  6. In the Port Number section, type the port number that you want the launcher to use for communication. Enter a port number that is not used by other services on the server, but which is open in the firewall on the server.

    noteNote
    If the Document Conversions Load Balancer Service and the Document Conversions Launcher Service are on the same server, the port numbers used for each service must be different.
  7. Click OK.
