tomcat7w.exe

[Markward Schubert <ma...@gmail.com>]

I have a short question.
Does the monitor exe do anything "magical" when a tomcat service is started
the first time with it, in contrast to starting the already installed
service with the windows service manager?

In fact our application would not start until we start the service from the
monitor exe.
Of course this is something in our app, but there must be some external
parameter, being "fixed" by running the exe first.

Monitor and servicemanagement both would be started "As Administrator", but
with different results.

After the Monitor was run once, the box seems to be in a "working" mode, so
after that, we can uninstall the service and delete the folder and do a
reinstall and everything would work, even without calling tomcat7w.exe.
This also makes debugging for me a bit hard at the moment, as the only
windows server 2012 box I currently have, is in "fixed" mode now.

Any help is very much appreciated!

Regards,
Markward

Thanks a lot for the advice, also to you other folks!
I thought about using some vm-boxes, but we decided to not invest further
into this issue at the moment. If this happens again in some setup, I will
digg into the problem again and will report, if I have any new information
or a solution.

Consider installing guest-VM software such as VirtualBox, VMWare, etc.
with a disk snapshot taken while you are in "broken mode". Then, you
can play with the configuration, launching, etc. and roll-back at any
time back into the broken state in order to try something else (or
verify that your last effort was correct).

I do this kind of thing all the time, and it is very effective.

Please do not "top post". It makes it difficult to follow the flow of the conversation.

And hi.
I do not know if this is the explanation to your particular issue, but consider the 
following :

1) what an "uninstall" procedure really removes and doesn't remove, is one of these 
Windows mysteries that are only accessible to wizards of the 7th circle, and mere mortals 
like you and I can only ever hope to wonder at the results.

2) when you/they initially installed the Service, was it installed so that the service 
would run under the "LocalService" (or "LocalSystem") special account, or was it installed 
so that the service would run under another user-id ?
If it was installed to run under another user-id, then one of the things that would happen 
in the background, is that this other user-id would have auto-magically received the 
"permission to run as a service" on the local machine, which is not granted to mere mortal 
users.
And this would not "un-happen" auto-magically when you remove Tomcat from the machine.
That is just an example of one of the things which are not symmetrical between installing 
and de-installing.  There are probably a lot more.

Hi David,

well my colleagues claimed, they did not change any parameter, wich I have
to believe until I create a fresh windows 2012 image to test myself, but if
they were wrong and they DID CHANGE something, would this not be reset, as
soon as we uninstall the service with the service.bat?

As far as I understand, these settings, being managed by the tomcat7w.exe
stick to a specific windows service and would be lost as soon as I remove
the service. Or are there any parameters, manipulating the OS' settings?

The funny thing is in fact, that after a complete uninstall subsequent
installs works from then on.

Did you maybe modify some of the Java parameters through tomcat7w?  It 
can do more than just start and stop the service; it can also modify the 
service startup parameters.

HTH!
