You can use the Database Configuration Wizard (dbcreatewizard.exe) to install multiple Operations Manager databases on a single instance of SQL Server. But before you can start it you need three files from a Ops Mgr installation.
- C:\Program Files\System Center Operations Manager 2007\ Microsoft.EnterpriseManagement.UI.ConsoleFramework.dll
- C:\Program Files\System Center Operations Manager 2007\ Microsoft.MOM.UI.Common.dll
- C:\Program Files\System Center Operations Manager 2007\ Microsoft.MOM.UI.Wrappers.dll
As many have question, how can I have the files if I not even have installed the database? You can copy these files from a machine that has Operations Manger 2007 Console installed, so install only the console on a machine that you will use as a management workstation later.
