3182.0. "DECwindows & UIS Together" by INTGRA::grb (George Brother) Wed Aug 08 1990 13:04

I have a customer with an existing UIS application who needs to continue to run
UIS on his VS3100. He would like to know if he can use the WS as a DECwindows
client at the same time, that is run a DECwindows application on the 3100 that 
will be displayed somewhere else. I would try this but I don't have a VS3100
running VMS at hand.

thanks,
George

3182.1UIS & DW client should coexist OKSTAR::ORGOVANVince OrgovanWed Aug 08 1990 18:549
    It should be possible to run DECwindows clients on UIS workstations
    with their output directed to a remote X server. In fact, it should 
    be possible to do this on _any_ VMS system running VMS V5.1 or later. 
    
    The sysgen parameter WINDOW_SYSTEM needs to be set to 1 only on a
    DECwindows server. 
    
    If you find out that this doesn't work, then it's a bug that should
    be reported.
3182.2different sets of SYSGEN params?AIRBAG::SWATKOElectrons are cheap. Trees are not.Thu Aug 09 1990 11:474
I thought DECwindows and UIS required radically different SYSGEN parameters.
That could be a problem.  Can anyone confirm/dismiss this?

3182.3Modified SYSGEN parameters only affect the serverSTAR::VATNEPeter Vatne, VMS DevelopmentThu Aug 09 1990 12:346
In general, the modified SYSGEN parameters only affect the server.
If you are using the VWS server, but are running DECwindows clients that are
displaying to another node, you should use parameters appropriate for VWS.

The only exception to this is general system parameters, such as GBLPAGES
and GBLSECTIONS.  Autogen should help you set these correctly.

    In a former lifetime, UIS->DW migration was my job.  It works just fine
    and always has.  The only gotcha's come from applications and command
    files that try to find out their environment...
    
    If the application is *strictly* a DECW or X11 application - no
    problem.  If the application does a UIS$PRESENT to see if it's on
    a UIS workstation - it won't work.  You will need to redirect the
    logical UISSHR to the UISSHR.EXE stub (which returns false) local
    to the process.  If the application checks for VA/VC/VK devices...
    you may be screwed unless you can change the source... MOST
    applications do not do this.  SOME command files do.
