Windass Management Instrumentation WMI and Common Information Model theme are related technologies.
Both are based on industry standards defined by the Distributed Management Task Force or the MTA, which
defines independent management standards that can be implemented across different platforms or vendor
enterprise environments.
WMI is Microsoft's implementation of the Web based enterprise management or the IBM standard, and is
an early technology that is based on preliminary standards and proprietary technology.
SYM is a newer technology and is based on open source platform standards.
WMI has been available on Windows operating system since Windows 24.
Most technologies provide a way to connect to common information repository, also known as the WMI
repository.
This repository holds management information that can be queried and manipulated.
Windows Power Shell supports both technologies.
Earlier versions of Windows Power shall support it on the WMI and Windows Power Shell of later than
3.0 version two parallel sets of commands.
Slatyer perform tasks by using either WMI or SIM.
SIM commands provide many different colours, cross platform and cross version capabilities that support
three kinds of connections connections to the local computer, which has always use decon ad hoc connections
to a remote computer which oversees the Web services for management or W.S. Man protocol.
This protocol is based on HTP and session based connections to remote computer, which can use either
discom or double YES-MAN protocol.
Dukedom connections are typically made to the Windows Management Instrumentation Service that is part
of the Windows operating system with Assman.
Connections are made to Windows Remote Management, or Winogrand Service, which is the same server
that enables Windows Power Scheller remote.
And we'll talk about remote a bit later in some other course in more detail.
In the room is part of the Windows management framework and is included in Windows Management Framework
Version two and newer versions.
Then Arima is installed by default on computers that are running Windows seven, Windows eight and so
on, although installed by default on all those operating systems.
You can assume commands in two ways.
The first Guerra's the remote computer to have the interim installed and enabled.
That will typically require the Windows management framework version three be installed and that Windows
power Scheller Motin is enabled.
The second way to use same commands is to tell the command to use the earlier WMI technology.
That is the same technology used by WMI commands, and it does not require that Windows management framework
be installed on the remote computer.
No to WMI commands.
WMI commands use the same repositories, same commands.
The only difference is in how the WMI commands connect to a remote computer.
WMI commands do not support assertion based connections.
The commands support only ad hoc connections over DECL, whether used by WMI or Assume Command.
Dickon can be difficult to use on some networks.
The com uses the remote procedure call or RBOC protocol.
That protocol requires specific firewall exceptions to work correctly, WMI commands communicate with
the WMI service.
They do not require an version of Windows management framework on a remote computer and they do not
require that Windows Power Scheller Motin be enabled is a remote computer, has a Windows firewall feature
enabled WMI commands require that the remote administration exception be enabled on the remote computer.
If the remote computer has a different local firewall enabled, an equivalent exception must be created
and enabled because.
Commands can also use the eCom WMI commands are typically necessary only when you have to make an ad
hoc connection to a computer that does not have Windows power Scheller remote and enabled.
So should you use WMI or assume most of the time you should use seem command LEDs instead of the older
WMI command?
Let's assume command.
Let's use the Comm One Cuarón, the local computer system command.
Let's use W Earthman for ad hoc connections to remote computers and same command that can use the command
W Earthman for session based connections to remote computer.
They are WMI commands that can be used when you must make an ad hoc connection to a computer that does
not have Windows management framework version to a newer version installed or to a computer that has
Windows management framework installed, but that does not have Windows power Scheller remote and enabled.
However, the same command that can connect to a computer that does not have Windows management framework
installed and two computers that do not have Windows power.
So the remote and enabled.
You must use the same session to connect to those computers.
You learn about six sessions a bit later in this course.
Please note Microsoft considers the WMI commands within Windows Power Shell to be deprecated.
Although the underlying WMI repository is still a current technology, you should rely primarily on
Simca commands and to use WMI commands.
Only one SIM commands are not practical.
The repository is not well documented and discover the classes that you might need to perform.
A specific task can be difficult and impractical.
The solution is to provide Windows Power Shell commands that behave like any other shell command, but
that internally use WMI or oracy.
The approach gives you the advantages of Windows power shell commands such as discoverability and in
documentation, while also giving you the existing functionality of the repository.
In Windows eight and Windows 2012, Microsoft introduced hundreds of new commands and Windows Paracel.
Many of the commands internally use WMI or Seyoum.
These commands provide better access to the functionality of WMI and SIM so that you can use the functionality
without having to deal with their complexity.
