Well, last night I tried to start the service on the client’s production
machine and I could not get it to work.
After registering the service from 4D server, I tried starting the service from
the Service Manager and it indicated that it had started up but I was unable to
establish a connection using a 4D client. On my VM Interactive Services takes a
while to show up in the task bar after a restart, but it eventually does. On
the production server, it never makes an appearance. So I have no other way to
see it the server is running properly.
I then restarted the computer with the service set to start automatically.
Again I was unable to establish a connection with 4D Client. I tried both
manually and automatically a few times without success. Each time I tried to
start up 4D Server normally and on at least one occasion 4D asked if I wanted
to open the database in Read Only mode, which tells me the service had opened
the datafile. On other tries, I was able to open the database normally.
A couple of other things to note.
1. A year or so ago I was investigating the ins and outs of running as
a service on this same machine and I was able to get everything to work.
2. I have the service 4D’s Application Server listening on port 19816
as I have another 4D server running a different database on the same box opened
normally (not as a service) listening on port 19813. It only opens after the
Admin user logs in. They both work fine together when both are opened normally.
3. The service 4D is also running a web server which respond to
requests from a Xojo WebApp running on the same machine. Those requests fail
when 4D Server is supposedly
running as a service.
5. Finally of note is that when the Xojo WebApp is opened as a Service
it will not open as it unexpectedly quits on startup. All of this, Xojo and 4D
Server work just fine on my VM and all worked fine a year ago when I first
started researching things on the production machine. The folks at Xojo suggest
that my WebApp may be trying to access a file that the service does not have
access to. Tonight I will be trying to get the Xojo service to work with no
file access queries in the WebApps startup events.
I think that the inability to start both the Xojo WebApp and 4D as services is
related and may be encountering an issue with the OS, which may have different
updates than my VM. The production machine has been religiously updated by
windows over the year,, my VM not so much.
Any suggestions?
Thanks,
John
