NAME
     wbem - Web-Based Enterprise Management

DESCRIPTION
     Web-Based Enterprise Management (WBEM) is a set  of  manage-
     ment and Internet-related technologies intended to unify the
     management of enterprise computing  environments.  Developed
     by  the  Distributed  Management  Task  Force  (DMTF),  WBEM
     enables  organizations  to  deliver  an  integrated  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:

        o  Common Information Model (CIM)  -  an  object-oriented
           data  model  that  describes the overall management 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.


        o  CIM  Operations  Over  HyperText  Transport   Protocol
           (HTTP)  1.1  is  a  transport  mechanism that maps CIM
           operations to HTTP to allow implementations 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  represented  textually  by  the  managed object format
     (MOF). These MOF representations  are  typically  stored  as
     text  files  that  developers  compile  into  a  CIM  Object
     Manager.

  WBEM Tools and Services

     vices   management  applications  and  instrumentation  that

     manage heterogeneous computer environments include:

        o  Solaris WBEM Services 2.5

        o  Solaris WBEM Software Development Kit 2.5

  Solaris WBEM Services 2.5
     These services consist of a set of value-added Services  2.5
     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 2.5 con-
     sists of:

        o  CIM Object Manager, CIM Repository, and MOF Compiler

        o  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.

        o  Solaris Providers, which are programs that communicate
           information  between the Solaris operating environment
           and the CIM Object  Manager  (providers  get  and  set
           "dynamic"  information  about managed elements, 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 configura-
     tion, for example. A remote provider is  also  available  to
     distribute  agents  away  from  the  CIM Object Manager when
     required. Because of the incremental  development  capabili-
     ties  of  the WBEM instrumentation framework, developers can
     progressively and consistently add more providers for  addi-
     tional Solaris software services.

        o  SNMP Adapter for WBEM, which  enables  Simple  Network
           Management  Protocol (SNMP) management applications to
           access system management 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) proper-
           ties 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 Nota-
     tion One (ASN.1) type for each object. Developers can create
     their own mapping files.

        o  SNMP Provider, which enables WBEM services to  deliver
           SNMP information.

  Solaris WBEM Software Development Kit 2.5
     This kit consists of  a  set  of  key  application  Software
     development  tools  that  make  it  easier for developers to
     write management applications that can communicate with  any
     WBEM-enabled  management  device.  The Solaris WBEM Software
     Development Kit includes examples,  documentation,  and  CIM
     Workshop,  a graphical user interface through which develop-
     ers can view and create classes and instances,  through  the
     remote method invocation (RMI) or the XML/HTTP protocol.

     Developers can also use this kit to write  providers,  which
     are  programs  that  communicate  with  managed  elements to
     access data.

     All management applications that developers create with  the
     Solaris  WBEM Software Development Kit run on the Java plat-
     form. The Solaris 9 WBEM Software Development  Kit  installs
     and  runs in version 1.4 of the Java environment. Developers
     can use the kit to write standalone applications or applica-
     tions that run in conjunction with Solaris WBEM Services.

     The Solaris WBEM Software Development Kit  is  described  in
     the Solaris WBEM SDK Development Guide. Javadoc for the WBEM
     application   programming   interface    is    located    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 map-
     ping 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 protocols.
