Management Pack References

Applies To: System Center Operations Manager 2007

Management packs often use elements such as base classes, monitor types, and modules in other management packs. Library management packs are automatically installed with System Center Operations Manager 2007 R2 to provide the core set of elements required by other management packs. For a management pack to use an element from another management pack, it must have a reference to that management pack.

Sealed Management Packs

A management pack can only use elements in another management pack if the management pack with the elements is sealed. The referencing management pack can be sealed or unsealed as shown in the following diagram.

Standard References

When a management pack is created by using the Authoring console, it automatically adds the standard set of references shown in the following table. The versions shown are for the Authoring console for Operations Manager 2007 R2 . Updates to the console can create updated versions of these references.

Alias Management Pack Version













Defining a reference

Each management pack reference includes the parts shown in the following table.


The alias is a short string that represents the referenced management pack throughout the current management pack. You can set the alias. It applies only to the current management pack. You can use any string of letters and numbers, although we recommend a short and descriptive string.

References that are created by the Operations Console have an alias automatically assigned. It can only be changed by exporting the management pack and editing the alias with an XML editor or the Authoring console. References created by using the Authoring console have an alias automatically created, but they can be changed at any time. The Authoring console will update any uses of the alias throughout the management pack.


The ID of the reference is the name of the referenced management pack.


The version of the reference is the minimum version of the management pack required by the reference. The version of the referenced management pack installed in the management group must be the same to or a later version than the version specified in the reference.

Public Key Token

The public key token is a unique character string representing the certificate that is used to seal the referenced management pack. This ensures that the management pack is provided by the expected source. If a management pack with the same name as the referenced management pack, but sealed with a different certificate, is installed in the management group, the token does not match.

Example References

The diagram below shows an example of the references for the Microsoft.SQLServer.2008.Monitoring management pack 6.0.6648.0. All of the management packs listed in the references must be installed in the management group before the Microsoft.SQLServer.2008.Monitoring can be installed. The minimal version of the Microsoft.SQLServer.Library and Microsoft.SQLServer.Discovery management packs are 6.0.6648.0. The version of these management packs installed in the management group must be equal to or later than 6.0.6648.0.

The other management packs require version 6.0.5000.0 or higher. These are library management packs that are included with Operations Manager 2007. Version 6.0.5000.0 of the management packs were included with the release version of the product. The library management packs for Operations Manager 2007 Service Pack 1 are version 6.0.6278.0 whereas the library management packs for Operations Manager 2007 R2 are 6.1.7221.0. These references ensure that the management pack installs on the release version of Operations Manager 2007. If a later version of the product were required for this management pack, a later version would be specified in the references.

The key token is identical for all of the references because these are all management packs provided by Microsoft and have been sealed with the same certificate.
