[Zope] Re: Mounting ZODB issue

Tue, 09 May 2006 07:51:04 -0700

Well, setting my Zope to run in Debug mode has shed some light on it, but I still do not know how to fix this. On trying to connect to the ZODB, I am getting the following error:

Many thanks for the advice.
Yes, the user does have read/write access to the zeo/var directory on the server and all of its contents. 

Still no joy though.

Do you have the appropriate access to the directory on the server? (ie. the process zope runs as needs to be able to read/write to the directory on the server).

Subject: [Zope] Mounting ZODB issue



Hi all,
I am trying to mount the ZODB of a Plone 2.0.5/Zope-2.7.6/Python 2.3.5 on a Plone 2.1.2/Zope-2.8.5/Python 2.3.5 

I have created the appropriate entry in the zope.conf thus...

<zodb_db weeble>
  mount-point /weeble
  <zeoclient>
    server 10.4.96.98:9999
    storage 1
    name zeostorage
    var $INSTANCE/var
  </zeoclient>
</zodb_db>
I know that this setup works on another Zope instance, because I cut and pasted it out of the zope.conf there. I do not believe that there are any firewall issues between the servers because a seperate instance on t the same machine is already connecting to this ZEO server.
The problem that I have is that when I create a ZODB Mount Point, the weeble mount point appears available but when I click Create the browser just sits there waiting for a reply that never comes. The ZODB Mount Point is not created. The Zope instance, however, does not appear to deadlock; I can just stop the browser browse the ZMI perfectly well.
Is this a Zope version issue? Is there a 'rule' in ZEO where it can only accept one connection from each client machine? Or have I just missed a step in the process? 

Many thanks in advance.
