Configuring a remote Document Conversion Service

To balance processing power, you can run document conversion services on a remote IBM® WebSphere® Application Server that supports document conversion services. Enabling the delegation of document conversion services to a remote server requires steps on both IBM WebSphere Portal and the remote server.

Before you begin

  • Update the content-types.properties file to ensure that document conversions are configured for different file types. For instructions, read Enabling Document Conversion Services.
  • Copy the RemoteDCS.zip file to your file system. Locate RemoteDCS.zip on the Components disk that is included with the WebSphere Portal setup disks.
    Note: Updated versions of RemoteDCS.zip might be available online. Check the Recommended fixes and updates for WebSphere Portal and Web Content Management site.

About this task

Local document conversion is supported on z/OS®. You do not have to run Document Conversion Services remotely for z/OS. If required, install the following package on the remote server to improve graphics performance with your document conversions: X11R6.

Linux on PowerPC®: Run document conversion services on a remote WebSphere Application Server that supports document conversion services. Local document conversion is not supported on Linux for PowerPC. Additionally, the 64-bit Linux on System z does not support running document conversion or spell checker locally. You must run these functions on a remote server.

Procedure

  1. Install WebSphere Application Server on the remote system.
    Restriction: Stellent version 8.01 must support the remote system.
  2. Copy RemoteDCS.zip to the remote server and extract it in any directory with an appropriate archiving tool. A directory named dcs becomes available. This directory contains several files and subdirectories.
  3. Deploy dcs.war to WebSphere Application Server.
    1. Log in to the WebSphere Integrated Solutions Console.
    2. Select Applications > Install New Application.
    3. Browse to the directory where you extracted RemoteDCS.zip then locate and select dcs.war.
    4. Specify dcs as the context root and click Next.
    5. Leave all other values as default.
      Restriction: The application name must be dcs_war. Do not change the default name.
    6. Map the application to the appropriate servers and specify the installation options as required.
    7. Click Finish and save your changes to the master configuration.
  4. Ensure dcs.war is running.
    1. Log in to the WebSphere Integrated Solutions Console.
    2. Select Applications > Enterprise Applications.
    3. Locate dcs_war in the list of installed applications.
    4. Select dcs_war and click Start if the application is not started.
  5. Run the configuration script.
    1. Open a command prompt.
    2. Change to the dcs directory. The configuration script is in the root of the dcs directory that is in the directory where you extracted RemoteDCS.zip.
    3. Run the following command:
      • AIX® Linux Solaris: ./setupremotedcs.sh
      • IBM i: setupremotedcs.sh
      • Windows: setupdcs.bat
    4. When prompted, specify the WebSphere Application Server installation directory. For example, AppServer_root.
    5. When prompted for the profile, specify the directory where dcs.war is installed. For example, AppServer_root/profiles/profile_name/installedApps/node_name/dcs_war.ear
    The configuration script copies all the required files to new directory named oiexport in the directory where you installed dcs.war; for example, AppServer_root/profiles/profile_name/installedApps/node_name/dcs_war.ear/dcs.war/WEB-INF/lib/oiexport
  6. Add the oiexport directory to the library path variable.
    Table 1. Platform and library path
    Platform Library path variable
    AIX LIBPATH
    Linux LD_LIBRARY_PATH
    Solaris LD_LIBRARY_PATH
    Windows PATH
    z/OS LD_LIBRARY_PATH, LIBPATH
  7. Restart the server. Document Conversion Services is now installed on the remote server.
  8. Open wkplc.properties with any text editor from the wp_profile_root/ConfigEngine/properties directory.
  9. Add the following property and value to wkplc.properties: DcsRemoteHost=URL of the remote host.

    Where URL of the remote host is the URL of the remote server to which you plan to delegate document conversion services. For example, DcsRemoteHost=http://server_name:port_number/dcs/dcs.

    Important: This property does not exist in wkplc.properties by default. You must add this property and specify a value before you proceed to the next step.
  10. Run the appropriate task to delegate some or all of the document conversion functions to the remote server.
    1. Open a command prompt.
    2. Change to the following directory:
    3. Run the following task:
      Note: Run the following command on all nodes in a cluster, if applicable.
      • AIX Linux Solaris: ./ConfigEngine.sh task_name
      • IBM i: ConfigEngine.sh task_name
      • Windows: ConfigEngine.bat task_name
      Where task_name is one of the following configuration tasks:
      Table 2. Tasks to delegate document conversion functions to a remote server.
      Task Description
      delegate-all-conversions This task delegates all file conversion services to a remote server.
      delegate-text-conversions This task delegates text document conversions to a remote server.
      remove-conversion-delegation This task ends the delegation of all file conversion services to a remote server.
  11. Restart WebSphere Portal.
  12. For z/OS, start the Customization dialog. Read Configuring the Portal Productivity Components for instructions on enabling remote Document Conversion Services. You must follow the Customization dialog instructions for submitting the customization jobs.
