Delaying Metadata Updates of Attributes
The force.update.metadata.on.open and update.metadata.on.load Windchill Workgroup Manager preferences allow you to delay the propagation of metadata (global attributes (IBAs) and system attributes) to obtain better performance. The force.update.metadata.on.open preference controls whether global attributes (IBAs) are updated upon open. The update.metadata.on.load preference controls whether metadata updates are delayed until switching to design mode.
Propagating attributes to CAD files increases the time needed to open files, compared to opening files when working standalone without Windchill Workgroup Manager. While this issue is not noticeable on single parts and small assemblies, opening large assemblies can take significantly longer when the CAD tool is connected to Windchill Workgroup Manager. If you regularly work with large assemblies, waiting for files to open can havea significant effect on your productivity.
These preferences provide the ability to exchange the temporary inaccuracy of metadata in a CAD session for improved system performance. For optimum performance, set both preferences to No. Remember that when the preferences are enabled, the attribute propagation is only postponed. There is no data corruption; there is only a temporary incorrect display.
Following are details about setting these preferences:
• These preferences are available in the wgmclient.ini file only, and are not available from Windchill Preference Management. (The wgmclient.ini file is located in the Windchill Workgroup Manager home directory.)
• You can set the force.update.metadata.on.open preference to:
◦ Yes (default)—Global attributes are updated for documents when they are opened in any mode, including visualization mode. System attributes are updated according to the value of update.metadata.on.load.
◦ No—Metadata is updated according to the value of update.metadata.on.load.
◦ Legacy—For legacy data, global attributes are updated according to the value of update.metadata.on.load. This preference is applied only to documents that do not have a neutral data XML file (models upgraded from a release prior to Windchill 9.0).
• You can set the update.metadata.on.load preference to:
◦ Yes (default)—Metadata is updated for a CATIA V5 document when it is loaded in any mode other than visualization mode.
◦ No—Metadata is not updated until a CATIA V5 document is loaded in design mode.

• If force.update. metadata.on.open is set to Yes, global attributes are updated for documents that are loaded in visualization mode, regardless of the value of update.metadata.on.load.
• When a drawing is loaded, metadata is updated for any CATIA V5 document that the drawing references with an attribute link, regardless of the value of update.metadata.on.load.
• If update.metadata.on.load is set to No, out-of-date metadata values are displayed in CATIA V5 for any CATIA V5 document that is not loaded in design mode.
