Professional SQL Server® 2008 Integration Services

Chapter 20. External Management and WMI Task Implementation

Throughout this book, you've been exposed to different ways to manage the development and administration of SSIS packages using the Visual Studio IDE and the SQL Server Management Studio. This chapter expands on those operations by providing an overview of the ways in which you perform these same management and administration functions programmatically through managed code. You learn how to perform package management operations using the managed Application and Package classes exposed in the dynamic-linked library Microsoft.SQLServer.ManagedDTS.dll by the .NET Microsoft.SqlServer.Dts.Runtime namespace.

The second half of this chapter details the capabilities of the WMI Data Reader Task and the WMI Event Watcher Task. These tasks provide access to system information via the Windows Management Interface model, better known as WMI. Through a query-based language called WQL, similar to SQL in structure and syntax, you can obtain information about a wide variety of system resources to assist you in your SQL Server administrative responsibilities. With WMI, you can mine system-based metrics to look for hardware and operating system trends. In SSIS, using WMI, you can also work more proactively to monitor a Windows-based system for notable events that occur in the system, and even trigger responsive actions.
