Hi Hugh,
Thanks for the quick response; this looks very helpful. See below.

Hi All,
The create and start directions for a Windows instance of Virtuoso work
fine for a virgin install, per
http://virtuoso.openlinksw.com/wiki/main/Main/VOSUsageWindows.
However, if I have any problems that cause me to shut down my machine
(due to development), I find I can still see the service listed, but can
not start from Control Panel --> Services or manually at the command
line with any options I try.
[Hugh] What do you mean by problems cause you to shutdown your machine ie
did the machine crash or is it gracefully shutdown and restarted ? The
Virtuoso service creation process set the service to start "automatically"
and thus it should be running by default after gracefully machine shutdown
and restart. I can thus only assume that the machine or possibly the
virtuoso server crashed leaving a "demo.lck" file in the "<Virtuoso dir>\
var\lib\virtuoso\demo" directory, which would need to be manually removed
before the server is started. Please check this directory to confirm if this
is the case and if so remove the file and then attempt the restart. Also, if
you check the "demo.log" file it should indicate the reason the server did
not start.
Great help! What I needed. BTW, is there no problem to remove the
"demo.lck" file? (I believe this file was present, but I have again
re-installed since.)
No, things have hardly been graceful! I'm doing much in the background
because I am attempting to move the VSPX files out of WebDAV (and who
knows what else is needed?) for local file editing (per Mitko's
suggestions on this forum on 4/24-25). (Good hints, but kinda incomplete!)
My use profile is therefore hardly standard. Rather than ending with
Virtuoso and ODS as is, I'm trying to start with ODS and then make major
mods (you know, learning anatomy by carving up cadavers!)
I've done some crazy/stupid stuff with NetDrive, plus other
self-inflicted wounds that require *ungraceful* shutdowns. One in
particular is trying to "clone" ODS outside of WebDAV that gets things
very mixed up.
(I know, don't try this at home, but the only way to get greater use of
ODS is for stubborn, but stupid, guinea pigs like me to break stuff in
every way possible! :) )
I'm kinda flying blind on this (keeping notes) and will likely need
major help come the beginning of the week. But, once started, I am
nothing if not stubborn! (and stupid! :) )
If you are still having problem then try starting the server with the
following command from the var\lib\virtuoso\demo folder:
virtuoso -fd -c demo.ini
This will start the virtuoso server in foreground debug mode detailing the
attempt to start the server and hopefully the reason for failure.
I use standard-type service commands (per Linux) as well as options like
listed here, but with virtuoso-t:
http://docs.openlinksw.com/virtuoso/installwin32.html#CreatingDeletingServices
And nothing seems to work. I end up having to re-install Virtuoso,
which is OK when developing, but not cool longer term.
[Hugh] A reinstall is never required you simply need to check the virtuoso
log file to determine the cause of the server failure to start as suggested
above.
1. Can someone document the open source Virtuoso service command
switches? (examples)
virtuoso-t -I Demo -S create -c demo.ini
virtuoso-t -I Demo -S start
[Hugh] If you run the command virtuoso-t -? this command will provide brief
descriptions of the all options that can be passed to the server.
It would be helpful to have all switches documented, what applies to
open source, etc.
2. Can someone document proper steps and sequence for service re-starts
and the procedure for re-starts?
[Hugh] As stated above their is nothing to document for restarting as the
server should restart automatically. What seems to be require is a simple
troubleshooting guide I would think ...
Well, plus the items above; again, most helpful.
Hugh, this is great! I will include in my running documentation.
Thanks, Mike
We shall see about adding some more documentation to the VOS documentation
detailing more start-up options and troubleshooting.
3. Any thoughts as to why the service can not be restarted through the
Services control panel?
[Hugh] See above ...
