Note: Download Microsoft SQL Server Management Pack for Operations Manager 2007 by Microsoft
The SQL Server Management Pack provides the capabilities for Operations Manager 2007 to discover SQL Server 2000, 2005 and 2008 installations and components and to monitor them, primarily from the perspective of availability and performance. The availability and performance monitoring is done using a combination of scripts and native Operations Manager capabilities.
Scripts in the SQL Server 2008 management pack rely on SQL Data Management Objects (SQL-DMO) to query information from the SQL Server. SQL-DMO is now deprecated and is not shipped as a part of SQL Server 2008. Every system with SQL Server 2008 that will be monitored must have SQL-DMO installed from the Microsoft SQL Server 2005 Backward Compatibility Components. For instructions on how to download and install the SQL Server 2005 Backward Compatibility Components refer to the management pack guide.
