For example, using WBEM, you could manage Linux and Windows
servers from the same location with equal ease??”at least, that??™s the theory. For the most part, the
theory does work and many companies have adopted WBEM as a base for performing management
tasks without platform considerations. In fact, the Distributed Management Task Force
(DMTF) has a number of standards for WBEM and you can see them at http://www.dmtf.org/
standards/wbem/.
NOTE This book does provide enough information about WMIC to help you perform most common
tasks. It doesn??™t document WMI or WMIC completely because the application is large and
complex enough to warrant a book of its own. If you find that you need additional information
about WMI, check out Understanding WMI Scripting by Alain Lissoir (Digital Press, 2003). This
book contains 579 pages on the topic of WMI scripting, including use of WMIC.
WMI is Microsoft??™s next step for WBEM. Even though this is still supposedly an open standard,
WMI builds on WBEM and implements it at a lower level. The instrumentation takes place through
device drivers, services, and other software, making the entire structure of a system appear more
as a hierarchical database than a collection of statistics that someone could use for management
tasks.
