Setting Property Values and Propagating Your Changes
The xconfmanager utility provides options that allow you to manage the properties in a Windchill property file as follows. You can:
Set a property value to specific value by using the -s and -t parameters.
Set a property value to the declared default value by using the following parameter:
--reset
Set a property value to null (instead of an empty string) using the following parameter:
--undefine
Add and remove property values from properties that are multi-valued using the following parameters:
--add
--remove
Propagate the site changes stored in the site.xconf file to all affected property files using the -p parameter.
Since property values are cached, propagated values are not used until you restart Windchill and your servlet engine.
