Issue with Data Warehouse instance collation

Veeam Management Pack for Microsoft System Center
5.7, 6.x
Last Modified:


After upgrading to nworks 5.7, Data Warehouse stops running. The following error message is displayed while generating reports:

Cannot resolve the collation conflict between "SQL collation "SQL_Latin1_General_CP1_CI_AS" and "{Your_SQL_Collation_Name}" in the equal to operation.


This can happen if Operations Manager Data Warehouse was installed into an instance with unsupported collation configuration. Please refer to the Microsoft KB article below for the list of supported configurations of SQL Server for Operations Manager:

NOTE: This particular error did not appear in earlier versions of nworks because nworks did not use full SCOM reporting capabilities. Since nworks v5.7, we have made a lot of changes and shipped new reporting features that use a wider range of SCOM reporting capabilities. Due to this fact, collation misconfiguration can cause errors that did not occur in previous versions of nworks.


If a SQL Server Collation other than "SQL_Latin1_General_CP1_CI_AS" is specified when installing, then OpsMgr will have to be reinstalled. Please see the Microsoft KB article below for details:

If the collation of the database is correct, but the collation of the SQL Server instance is wrong, the database can be migrated to a SQL Server with correct collation configuration. The procedure is available through this link:
