How to Seal a Management Pack in Operations Manager

Updated: January 31, 2012

Applies To: System Center 2012 - Operations Manager

You can use the Operations Manager class libraries to seal a management pack. A sealed management pack is a binary file that cannot be edited. An unsealed management pack is an XML file that can be edited. Sealed management packs should have an .mp extension, and unsealed management packs should have an .xml extension.


This example demonstrates how to seal a management pack that has been imported into a management group. For information about importing management packs, see How to Import a New Management Pack.
