init.wbem(1M)

NAME

     init.wbem - start and stop the CIM Boot Manager

SYNOPSIS

     /etc/init.d/init.wbem start  |  stop  |  status

DESCRIPTION

     The init.wbem utility is run automatically during  installa-
     tion  and  each  time  the  system is rebooted. This utility
     manipulates the CIM Object Manager (CIMOM) and  the  Solaris
     Management  Console  server, both of which run combined in a
     single process. init.wbem can be used  to  start,  stop,  or
     retrieve status from the server.

  CIM Object Manager
     The CIM Object Manager manages CIM objects on a WBEM-enabled
     system. A CIM object is a computer representation, or model,
     of a managed resource, such as a  printer,  disk  drive,  or
     CPU. CIM objects are stored internally as Java classes.

     When a WBEM client application accesses information about  a
     CIM  object,  the  CIM  Object  Manager  contacts either the
     appropriate provider for  that  object  or  the  CIM  Object
     Manager  Repository.  Providers are classes that communicate
     with managed objects to access data.

     When a WBEM client application requests data from a  managed
     resource  that  is not available from the CIM Object Manager
     Repository, the CIM Object Manager forwards the  request  to
     the provider for that managed resource. The provider dynami-
     cally retrieves the information.

     At startup, the CIM Object Manager  performs  the  following
     functions:

        o  Listens for RMI connections on RMI port 5987  and  for
           XML/HTTP connections on HTTP port 5988.

        o  Sets up a connection to the CIM Object Manager Reposi-
           tory.

        o  Waits for incoming requests.

     During normal operations, the CIM  Object  Manager  performs
     the following functions:

        o  Performs security checks to  authenticate  user  login
           and authorization to access namespaces.

        o  Performs syntactical and semantic checking of CIM data
           operations  to ensure that they comply with the latest
           CIM Specification.

        o  Routes requests to the appropriate provider or to  the
           CIM Object Manager Repository.

        o  Delivers data from providers and from the  CIM  Object
           Manager Repository to WBEM client applications.

     A WBEM client application contacts the CIM Object Manager to
     establish  a connection when it needs to perform WBEM opera-
     tions, such as creating  a  CIM  class  or  updating  a  CIM
     instance.  When  a WBEM client application connects to a CIM
     Object Manager, it  gets  a  reference  to  the  CIM  Object
     Manager,  which  it then uses to request services and opera-
     tions.

  Solaris Management Console Server
     The Solaris Management Console server is the back end to the
     front  end  console, smc(1M). It provides tools for the con-
     sole to download and performs common services for  the  con-
     sole  and its tools to use, such as authentication, authori-
     zation, logging, messaging, and persistence.

  System Booting
     The init.wbem script is installed in the /etc/init.d  direc-
     tory.

OPTIONS

     The following options are supported:

     start Starts the CIMOM and Solaris Management Console server
           on the local host.

     stop  Stops the CIMOM and Solaris Management Console  server
           on the local host.

     status
           Gets the status of the CIMOM  and  Solaris  Management
           Console server on the local host.

NOTES

     When the init.wbem script is run, it does not run the  CIMOM
     and  Solaris  Management Console server directly. The server
     process is in Java and is too heavyweight to be run  immedi-
     ately  at  system  boot  time.  Instead,  three  lightweight
     processes listen on three different ports that the CIMOM and
     the  Solaris  Management  Console  server normally use. This
     acts similarly to inetd(1M).

     Because Java programs cannot  inherit  file  descriptors  as
     other  programs  can, there is a small time period from when
     the first connection is  made  until  the  server  is  fully
     operational  where  client  connections may be dropped. WBEM
     clients are immune to this, as they  will  retry  until  the
     server  comes online. Solaris Management Console clients are
     not immune, and it may be necessary to  manually  reconnect,
     though this should not happen in the common case.
