[CDO] Connection failures [message #105021] Sat, 22 December 2007 00:48 Go to next message

Hi,
I'm experimenting with tutorials and the 0.8.0 version of CDO.

To start I downloaded the pre-installed Server.
Is this 0.8.0 compatible?

Also since my development and testing platform is a Linux machine, I
would like to install the server on my Linux system. Is there a
pre-installed Linux version or linux startup scripts already built for
derby and the cdo server?

Nevertheless to expedite the testing of CDO, I installed the Windows
based server on a windows box in my lab using the default configs and
from my Linux based Eclipse Desktop with 0.8.0 CDO and it's dependencies
loaded I attempted to open a session to the repo on the Windows box.
Here is my connection uri:

tcp://guppy:2036/repo1

But I get the message:
Unable to open a session on the specified repository.

Any ideas what I need to do to overcome this problem?

thanks,
John

Hi John,

Your problem most probably results from using a newer client with this
quite old server pre-installation. Since it's on the wiki it always gets
out-dated rather qickly. To prevent others from running into this trap
I'll remove the download from the wiki until I found a solution to
include a server preinstallation into the automatic build.

The best approach is to generate a new server installation from the file
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.emf/org .eclipse.emf.cdo/features/org.eclipse.emf.cdo.server.product /CDOServer.product?root=Modeling_Project&view=log
... When you checked out all the sources via All.psf it is found in the
org.eclipse.emf.cdo.server.product feature. This way you should be able
to tweak the installation for linux as well.

If the problem still persists be so kind to open a new Bugzilla.

Eike Stepper

John,

I forgot to mention that you can also just start the CDOServer launch
config to run the server in the console of your IDE. That's what I'm
doing while developing. If you configure an embedded Derby database you
even don't have to install a separate DB server (but debugging the CDO
server can get rather slow then)..

Great! BTW. I just fixed a bug that caused a signalling deadlock in rare
race conditions. You might want to update from CVS until this fix is in
this weeks build.

Happy New Year ;-)
