Managed objects are made visible over the interoperable interface. All of the
managed objects made visible by one OS to one other OS make up a set called
the Management Information Base (MIB). As seen by another OS, the
managed objects in a MIB appear to be inside the OS that ;SPM_quot;owns;SPM_quot; the MIB.
Since managed objects make up the total management view provided across
the interoperable interface, the MIB is the repository of all management
information in a OS.
In the context of managed objects, the phrase ;SPM_quot;make visible;SPM_quot; is not limited to
a passive role, but includes both observation and manipulation of a managed
object. Stating that a OS makes a managed object ;SPM_quot;visible;SPM_quot; means that the
OS will allow other OSs to know the managed object's name (thus
acknowledging the existence of the managed object), and may allow other OSs
to manage the managed object.
The contents of a MIB is dynamic, and reflects only those managed objects
which exist at any point in time. In addition, a OS may make different sets
of managed objects visible to different OSs, for security or other reasons.
The set of managed object classes that a OS can support is a part of the
shared conceptual schema. A OS is said to support a managed object if it can
either or both of the following:
It can perform operations (create, get, etc.) on instances of the class
or receive notifications (event reports) from instances of the class (i.e. it can
manage instances of the class). This includes a semantic understanding of the
definition of the managed object class.
It can make instances of the class visible to other OSs.
