Disable thumbnail synchronization for all users

Image thumbnails synchronize every 30 minutes as the IXIA CCMS default. IF this causes performance issues, you can disable thumbnail synchronization for all users, regardless of their personal settings.

About this task

When thumbnails are created, they are stored on the server and become available to all users after the next thumbnail synchronization. For a deployment with very large Content Store, thumbnails can use a lot of space. In such cases, disabling synchronization can improve latency.

Important: Make configuration changes in a test environment and confirm they work before copying them to a production environment.

Procedure

  1. In the TEXTML Administration perspective, connect to your server.
  2. Locate the multiimage.xml file in the repository's /system/conf collection.
  3. Check out the file and open it for editing.
  4. Locate the <thumbnails> element and set the @allowThumbnailSynchronization attribute to false.
    For example:
    ...
<!-- Thumbnails settings for images -->
<thumbnails defaultscale="0.5" minsize="150" maxsize="600" allowThumbnailSynchronization="false"/>
...
    This attribute disables thumbnail synchronization, regardless of the users' personal settings. When @<allowThumbnailSynchronization> is set to false, the Synchronize Image Thumbnails option in the Synchronization Preferences is dimmed and the following message displays: 
    [disabled by system administrator]
  5. Save, close, and check in the file.
  6. Inform users of the changes.
    The changes are automatically applied once users close and then reopen their IXIA CCMS Desktop. Users can also apply the changes without restarting their CCMS Desktop by clicking IXIA CCMS > Synchronize Configuration.
