wbem(5) Standards, Environments, and Macros wbem(5)NAMEwbem - Web-Based Enterprise Management
DESCRIPTION
Web-Based Enterprise Management (WBEM) is a set of management and
Internet-related technologies intended to unify the management of
enterprise computing environments. Developed by the Distributed Manage‐
ment Task Force (DMTF), WBEM enables organizations to deliver an inte‐
grated set of standards-based management tools that support and promote
World Wide Web technology. The DMTF has developed a set of standards
that make up WBEM. This set of standards includes:
Common Information Model (CIM)
CIM is an object-oriented data model that describes the overall manage‐
ment of information in an enterprise network environment. CIM consists
of a CIM specification and a CIM schema:
CIM Specification Consists of the language and methodology that
describes management data.
CIM Schema Provides actual model descriptions of systems,
applications, large area networks, and devices.
The CIM Schema enables applications from dif‐
ferent developers on different platforms to
describe management data in a standard format.
As a result, a variety of management applica‐
tions can share this information.
CIM Operations Over HyperText Transport Protocol (HTTP) 1.1 is a trans‐
port mechanism that maps CIM operations to HTTP to allow implementa‐
tions of CIM to interoperate in an open, standardized manner.
CIM Operations Over HTTP 1.1 uses eXtensible Markup Language (XML),
which is a markup language that represents management information in
textual form.
In addition to the XML representation, CIM information is also repre‐
sented textually by the managed object format (MOF). These MOF repre‐
sentations are typically stored as text files that developers compile
into a CIM Object Manager.
WBEM Tools and Services
Tools and services that enable developers to create and Services man‐
agement applications and instrumentation that manage heterogeneous com‐
puter environments include:
· Solaris WBEM Services
· Solaris WBEM Software Development Kit (SDK)
Solaris WBEM Services
These services consist of a set of value-added Services components.
These services make it easier for developers to create management
applications that run in the Solaris operating environment. They also
make the Solaris operating environment easier to manage. Solaris WBEM
Services consists of:
· CIM Object Manager, CIM Repository, and MOF Compiler
· CIM and Solaris Schema, which is an extension schema of CIM. CIM
and Solaris Schema is a collection of CIM classes that describe
managed elements in the Solaris operating environment. These
classes are available from the CIM Object Manager at start up.
· Solaris Providers, which are programs that communicate information
between the Solaris operating environment and the CIM Object Man‐
ager (providers get and set dynamic information about managed ele‐
ments, acting as an intermediary between the CIM Object Manager
and the managed elements).
Solaris software providers have been developed for a variety of
areas: users, roles, file systems, and network configuration, for
example. A remote provider is also available to distribute agents
away from the CIM Object Manager when required. Because of the
incremental development capabilities of the WBEM instrumentation
framework, developers can progressively and consistently add more
providers for additional Solaris software services.
· SNMP Adapter for WBEM, which enables Simple Network Management
Protocol (SNMP) management applications to access system manage‐
ment information that is provided by Solaris WBEM Services. Used
with the Solstice Enterprise Agent (SEA) Master Agent snmpdx(1M),
the SNMP Adapter for WBEM maps SNMP requests into equivalent WBEM
Common Information Model (CIM) properties or instances.
The SNMP Adapter for WBEM also remaps the response from the CIM
Object Manager into an SNMP response, which is returned to the
management application.
A mapping file contains the corresponding Object Identifier (OID),
class name, property name, and Abstract Syntax Notation One
(ASN.1) type for each object. Developers can create their own map‐
ping files.
· SNMP Provider, which enables WBEM services to deliver SNMP infor‐
mation.
Solaris WBEM SDK
The Solaris WBEM SDK is a set of application programming interfaces
(APIs) that contain the components necessary to write management appli‐
cations. These applications communicate with WBEM-enabled management
devices by using XML and HTTP communication standards.
Solaris WBEM applications request information or services from the Com‐
mon Information Model (CIM) Object Manager through the WBEM APIs. These
APIs represent CIM objects as Java classes. The APIs are used to
describe managed objects and to retrieve information about managed
objects in a system environment. The advantage of modeling managed
resources by using CIM is that those objects can be shared across any
system that is CIM-compliant.
For more information on the Solaris WBEM SDK, see the Solaris WBEM
Developer's Guide. The Solaris WBEM API documentation is available in
Javadoc format with the Solaris OS installation at
/usr/sadm/lib/wbem/doc/index.html.
Compatibility of Solaris WBEM Services with Existing Protocols
Adapters and converters enable Solaris WBEM Services of Solaris to work
compatibly with existing protocols by mapping WBEM information to these
protocols. One such protocol is Simple Network Management Protocol
(SNMP).
Legacy management applications can administer WBEM-enabled software in
the Solaris operating environment. Developers can write agents or
providers that convert information from these protocols to WBEM, and
they can write adapters that convert WBEM information into these proto‐
cols.
