Grass Valley iTX System v.2.6 - Manual (Page 348)

Using Missing Materials Manager
You use the panel features to:
• Switch auto-purging on or off.
• Specify whether or not Missing Materials Manager should delete the file record when
it deletes a media file.
• Specify the criteria that identifies which media files Missing Materials Manager may
select for deletion. You should ensure that the criteria you specify does not allow
Missing Materials Manager to delete media files you want to keep.
• Set values – percentages of total disk space – for high and low water marks.
Note:
• After the installation of Missing Materials Manager, an activation file is needed to
make auto-purging available. The requirement is to prevent the accidental deletion of
media due to incorrect configuration of the service.
For information on how to activate auto-purging, contact iTX Support.
Set up Missing Materials Manager to automatically delete unwanted media files from a
Media Store
After installing the activation file to make auto-purging available, you need to do the following
to set up Missing Materials Manager to use this functionality.
1.
In the Missing Materials Manager window, select the Engineering, General tab.
2. In the box to the right of the Activate Auto-Purge button, select one of the options to
control the way in which Missing Materials Manager deletes media files:
• Purge Clip (and media).
• Purge Media only. Ensure you select this option if you are configuring one of a number
of instances of Missing Materials Manager.
3. Do the following to set up PinPoint to search for files.
• Click Set Purge Criteria to open the PinPoint dialog.
• Specify the criteria that identifies media files that are not required in the near future.
• Click OK to close the PinPoint dialog.
Note: Even if a media file meets the specified criteria, Missing Materials Manager does not
delete it if an event that falls within the look-ahead time needs it.
4. Position the High water mark and Low water mark sliders to set the points that control
when Missing Materials Manager starts and stops deleting files.
Note: You should set a low water mark that is about 10 to 20% below the high water mark.
This results in frequent low-volume purges.
5. Select Activate Auto-Purge.
Prevent Missing Materials Manager automatically deleting media files
