DECwindows in heterogenous environment? (Mac)

» close window

The Question is:

 
We are trying to set up an Xwindow environment on a Mac using Exodus
software to output applications from an OpenVMS workstation. We are
currently able to set display from the VMS machine running OpenVMS 7.1-1 to
the Mac with TCPIP transport and UCX. But,
 we would like to be able to run clients from the Mac.
What do we need to do on the VMS machine to allow the Exodus on the Mac to
open a session and run commands? We have already set the Session Manager
Security to allow the Mac and the user access. What other settings on the
VMS machine are required and/or w
hat commands do we need to issue on the client side?
Anything you can offer will be GREATLY appreciated!
 

The Answer is :

 
  X Windows clients connect to the X Windows server assocated
  with the particular X Windows display -- if you want your
  clients to operate on the Macintosh or other system, they
  will have to connect to and communicate with the X Windows
  server -- apparently "Exodus" running on the Macintosh, in this
  case, but OpenVMS workstations with DECwindows also provide a
  local X Windows server -- through whatever means specific to and
  available to the X Windows server.
 
  Each X Windows server login also typically has a session manager,
  and this can operate on the same system as the X Windows server,
  or it can provide its services while operating on a remote system.
 
  If you wish to have the local system initiate applications for
  use on the OpenVMS system and subsequent display back to the
  X Windows server on the local system, most any communications
  mechanism (supported by both the local system and OpenVMS) can
  be used.  Examples include DECnet, IP (rsh and rexec), telnet,
  etc.  The portion of the application -- the X Windows client --
  that is operating on OpenVMS must issue the appropriate SET
  DISPLAY command, in order to allow the X Windows client application
  to find and connect to the appropriate X Windows server.
 
  DECnet task-to-task communications are discussed here in Ask The
  Wizard, you will want to check the platform documentation for
  information and availability of IP tools such as rsh and rexec.
  (TCP/IP Services provides rsh and rexec server capabilities, and
  can thus accept and act upon commands provided by the rsh or rexec
  client operating on the local system -- the Macintosh, in this case.)
 
  For assistance on the Macintosh system and the available commands
  and capabilities, you will need to contact a Macintosh Wizard.
