Dropped connection from Shared IJC database

Hi.

I have a shared IJC (5.9.3) database in Oracle 10g.  Users have reported dropped connections sporadically whilst scrolling/ seraching in forms.  Please see the error message attached.  Please can you explain what the problem might be?

Thanks,

MIke.

Hi Mike,

 

Sorry to hear about these issues.

It looks like from the error that somehow the network reference to the shared config file (.ijs) is being lost for the project, perhaps under some intensive activity like scrolling many records...

If you have the full (messages.log) files for any instances of this problem that would help us some what to see if there are any other indicators of the cause. You can send any to "ijc-support atsymbol chemaxon.com"

Is it possible there is any network issue between the server and client machine ?

(An independent test might confirm but I only know of ping as test)

 

Cheers,

Daniel.
