SYNOPSIS

       broker_allup [-hVf] [-o filename] [-p PID-filename]

DESCRIPTION

       The broker_allup utility is a "super" server that is  used  to  dynami-
       cally  load the CPU Broker's shared libraries and instantiate its CORBA
       objects.  By default, the server exports a single object that  is  used
       to  load  shared  libraries  into the process.  Once a library has been
       successfully loaded, an IOR is returned that can be  used  to  interact
       with  the library.  For example, creating a "Manager" object is done by
       loading the Broker's main library, libcpu-broker, into broker_allup and
       using  the library object to create the manager.  Of course, doing this
       all by hand can be tedious, so the CPU Broker includes a shell  script,
       broker_allup_default(1),  that  takes care of most of the work for you.
       This script starts broker_allup in  the  background  and  constructs  a
       default  configuration of objects using the cbhey tool that is included
       with the Broker.

       The set of libraries included with the  Broker  is  listed  below.   As
       always, cbhey's "getsuites" command can be used to get the online docu-
       mentation for each library.

       libcpu-broker
              Contains the manager class and the base real-time task class.

       libpolicies
              Contains  the  following  contention   policies:   StrictPolicy,
              WeightedPolicy, and PartitionPolicy.

       libdelegates
              Contains  the basic delegate classes for several Broker objects.

       libtask_factories
              Contains several real-time task delegate  classes  that  perform
              some type of adaptation.

       User  defined  libraries  can also be loaded by broker_allup.  The only
       requirement is  that  they  follow  the  interface  described  in  fac-
       tory_library.h(3).

       Available command line options:


       -h     Display a usage message

       -V     Print out a version number.

       -f     Fork into the background after everything is setup.

       -p PID-filename
              Specify  the file name to store the process' ID.  By default, no
              file is written.

       -o filename
              Specify the file name for the Allup object's  IOR.   Default  is
              "./allup.ior".

RESOURCE RESERVATIONS

       When  running  on  TimeSys  Linux,  broker_allup will create a soft CPU
       reservation for itself if it is not given one externally.  This  is  to
       ensure  that  the  Broker  objects will be able to handle requests in a
       timely manner.

EXAMPLES

       To start the program in the background and  have  its  IOR  written  to
       "./allup.ior":

              [nemo@anemone /tmp] broker_allup -f

       To then load a library named "foo" and save its IOR in "foo.ior".

              [nemo@anemone  /tmp]  cbhey file://allup.ior create library with
              name /path/to/foo > foo.ior

       To create an object using  the  "foo"  library  and  save  its  IOR  In
       "bar.ior".

              [nemo@anemone /tmp] cbhey file://foo.ior create bar > bar.ior
