MBX_HELPER -- Establish ability for inter-node interprocess communication.
usage:  MBX_HELPER [-MAXCHAN channels] [-DATASIZE byte_count] {CL}


  MBX_HELPER is a program residing in the /SYS/MBX directory of your node which,
  when executed, allows your node to  handle  interprocess  communications  with
  other nodes (also running MBX_HELPER) in your network.  Normally, this program
  runs in a background process, and is started automatically by  programs  which
  require its services (like SPM, the Server Process Manager).  You may start it
  manually, if you wish, by using the DM commands CPO or  CPS  either  from  the
  keyboard  or  from within a DM startup script.  You should probably use CPS so
  that the process persists across user logins and carries a system  SID.    See
  HELP CPS for more information.

  MBX_HELPER takes a standard CL command line with the following options:

  -MAXCHAN channels
                  Specify the maximum number of  remote  channels  to/from  this
                  node using MBX.  The default is 128.

  -DATASIZE byte_count
                  Specify the queue data size for each channel.    This  is  the
                  maximum  number  of bytes that can be buffered at one time for
                  remote MBX channels.  The default is 1158.

  Startup File

  When programs such as SPM start MBX_HELPER automatically, they check  for  the
  file `NODE_DATA/STARTUP.MBX_HELPER and read it if it exists. This startup file
  may contain either or both of  the  options  described  above,  plus  comments
  prefixed  by  the  Shell  comment  character '#'. If the startup file does not
  exist, MBX_HELPER executes using the default values for both options.

  EXAMPLE

    cps /sys/mbx/mbx_helper -n mbx_helper

  This starts the server with the default channel and queue  data  size  values.
  The  -N  option  applies  to  the  CPS  command  and assigns a name to the new
  process.
