Client update failed to read file information from the server database

Citrix.PresentationServer.ClientUpdateFailedToReadFileInformationFromDB.Rule (Rule)

Raises an alert if an automatic client update component failed to read file information from the server database

Knowledge Base article:

Citrix ® Management Pack

Summary

The server failed to determine file properties that are required to initiate an automatic client update, due to a problem with the server's client update database. The session will continue without automatic client update.
 
Causes

To determine which files need to be updated on a client installation, the server compares the properties of the files currently used by the client with the corresponding files in the client update database. This event indicates that an error occurred while the server was determining the properties of the file shown in the event description. This suggests that the update database may be corrupt, or that the indicated file cannot be accessed; for example, due to insufficient permissions.
 
Resolutions
  • Ensure that the server's client update database is not corrupt. If it is, regenerate it using the ICA Client Update Configuration utility. See the Citrix Presentation Server Administrator's Guide for more information.
  • Check that the indicated file exists and has appropriate permissions: at least read access for all users.
