R
real time
Of or related to a timeframe imposed by external constraints. Real-time operations are either those in which the computer's activities match the human perception of time or those in which computer operations proceed at the same rate as a physical or external process.
reference
A special string property type that is marked with the reference qualifier, indicating that it is a pointer to other instances. Used in MOF syntax as ref, for example, SMS_Resource ref invResource.
See also qualifier.
Remote Procedure Call (RPC)
A protocol used to activate functions on a remote computer and retrieve the result.
resource
An object, such as a computer, a router, or a Windows NT/Windows 2000 user group, that can be discovered and potentially be managed by SMS. Resources can be organized into collections.
See also collection.
resource class
In SMS, manageable resources are divided into these classes:
System Resource
Personal computers, servers, and network devices, such as routers.
User Group Resource
Windows NT/Windows 2000 User Groups.
User Account Resource
User accounts on computers running Microsoft Windows NT/Windows 2000 network operating systems.
See also query.
Resource Explorer
An SMS Administrator console feature that displays the hardware and software inventory collected from clients.
See also client; inventory.
Resource Manager
A Software Metering tool that enables existing users, groups, and computers to be added to a master list. This list can then be used to restrict software use based on user name, group membership, and the computer used to access the network. The user name can also be used to set a callback priority other than the default.
See also callbacks; master list.
RPC
See Remote procedure call.
run-time class
A run-time class has a schema that may change while SMS is running because it represents an SMS object that has an extensible schema. The schema will only be expanded by the creation of new properties, but existing properties will never be changed. A run-time class does not have a definition directly in the _smsprov.mof file because its definition is created by the SMS Provider itself. However, a run-time class may be accessed in the Common Information Model (CIM) repository in the same manner as a static class. Also, for many run-time classes, there is a set of predefined properties, which are listed in the class reference section of each run-time class.
Run-time classes are derived from static classes that appear in the **_**smsprov.mof file. For example, the static class, SMS_Group, is an abstract class, from which other specific inventory classes are derived. These sub-classes derived from it are then used to create instances based on those classes. The SMS Provider creates these derived classes and instances at run time.
Though not part of the _smsprov.mof file, the run-time classes represent important parts of the functionality of the SMS Provider. Wherever possible, the hierarchy of these classes and the important properties in them have been included in the Class Schema Reference part of the documentation.
The other type of class described in the SMS SDK is the static class.
