    Hi need some information on the object X$X0.
    Why some times decw starts but the object is not present?
    Where can I find more information on this object?

2985.1X$X0 created by DECnet transport interfaceSTAR::VATNEPeter Vatne, VMS DevelopmentTue Jun 26 1990 14:3617
The X$X0 object is created by the DECnet transport interface when the
DECwindows server is started.  This object will not be created under
the following conditions:

1) If you override the default list of transports through the file
   SYS$MANAGER:DECW$PRIVATE_SERVER_SETUP.COM, and don't include the
   DECnet transport interface.  For example:

	decw$server_transports == "TCPIP,LOCAL"

2) If DECnet is not started.  In that case, the DECnet transport
   interface will check once a minute to see if DECnet has been
   started yet.  As soon as DECnet is started, then the X$X0
   object should be created.

I strongly suspect case #2 is your problem.  What version of
VMS are you using?

2985.3Suggest upgrading to VMS V5.3STAR::VATNEPeter Vatne, VMS DevelopmentWed Jun 27 1990 14:2311
I definitely think your problem is a race condition between DECnet
starting and DECwindows starting.  This can easily happen if in
SYSTARTUP_V5.COM, you start DECnet in a batch job instead of in-line.
In VMS V5.1 and V5.2, DECnet must be started before the DECwindows
server is started.  If the server does start before DECnet, the only
workaround is to restart the server.

This is not a problem with VMS V5.3 and later.  That is the version
where the DECnet transport interface will automatically check once a
minute to see if DECnet has been started.  I recommend that you upgrade
to VMS V5.3.
