User Preference Persistence

When using a WCC application, user preference data is always stored on the server. This includes things like view definitions, column settings, information on the Options dialog, list filter and sort settings, etc.

This configuration is used to set the maximum number of bytes for the user preference data. This value needs to be set at or below the field size supported by the database used on the server.

If this value is too small, processing the data at the server will be inefficient; if it’s too large, the database will throw an exception when is attempts to parse the message containing user preference data.

Note that the character encoding used should be taken into consideration when determining the maximum data size.

Procedure

  1. In the Configuration Administrator, click config.xml in the left pane.
  2. In the Graphical Editor tab, click in the User Preference Persistence section:
  3. Configure the maximum data size using the following field that appears in the right pane:
    • Maximum number of bytes for user preference data - Set according to the description above. The default is 1992; the minimum is 10.
