Strange behaviour with automatic DECterm at Startup
|
|
|
Hello Managers,
I'm not sure that it's a TRU64 Unix problem but it should be.
My workstation is an OpenVMS workstation. At login time, I have some
tasks in the automatic startup menu and some of them are opening DECterm
windows in wich there are automatic rlogin commands on Tru64 Unix
computers.
I've always got problems with some of them following the Tru64 Unix
version : after a fix number of seconds the Decterm is closed even if I
was typing some characters and the process running is stopped. Then I
was able to start again the same process from the Session Manager and
the window never closed, so it seems that it's not an autologout time
problem.
Now all my Unix systems are running 5.1A and for all the systems but one
the window is closed after some 90 seconds.
The running shell is tcsh. The .login and .cshrc files on the user
account are the same.
Some ideas about this strange behaviour ?
Thank you in advance,
Daniel Clar

Thank you to Selden E Ball Jr <SEB@LNS62.LNS.CORNELL.EDU> and I join the

Check to make sure you don't have an "idle job killer" running
on the VMS sytesm. They are sometimes confused about how
to handle DECwindows.
I've never seen the problem you report, but you might consder a
different login method. Specifically, use rsh to run dtterm (or dxterm)
on the Tru64 systems, so that the Tru64 terminal emulator opens
a window on your VMS desktop. As a result, you are using a terminal
emulator that is running native on the remote Unix system rather
than using rsh within a VMS DECterm window.
This avoids many potential terminal emulator incompatibilities.
I usually use dxterm, since it is almost identical to the VMS DECterm.
I use the subroutines below within my auto-login script to open either
a DXterm or a DTterm window on the current X display screen.
The DCL subroutines are called with p1 set to be the remote host name.
e.g.
$ call rlg_dxterm host.computer.domain
They are spawned from a terminal window that is "never" logged out.
You'll have to change how "d1" (the local display's tcp/ip domain name)
is determined if you don't use Multinet.
$!=====================================================
$! Routine to rsh to remote unix and open DXterm window there to here
$rlg_dxterm: subroutine
$ wn = p1
$ def/user sys$output nl:
$ sho disp/sym
$ d1 = "''decw$display_node'"
$ if d1 .eqs. "0" then d1 = "''f$trnlnm(""MULTINET_HOST_NAME"")'"
$ d2 = "''decw$display_server'"
$ d3 = "''decw$display_screen'"
$ spawn/nowait/input=nl: -
rsh 'p1' "/usr/bin/X11/dxterm -display ''d1':''d2'.''d3' -iconic -xrm
""*iconName:''wn'"" -
-xrm ""*title:''wn'"" "
$ exit
$ endsubroutine
