Description tenor

Build Identifier: 

Network Protocol Features 
Net4j based binary application protocol 
Pluggable transport layer (shipped with NIO socket transport, polling HTTP and
JVM embedded transport) 
Pluggable fail over support 
Pluggable authentication (shipped with challenge/response negotiation) 
Multiple acceptors per server

http://wiki.eclipse.org/CDO

We need to have low latency/high bandwidth setup, perhaps with Citrix. this
kind of network features will be a bit of problem or value add ?

Thanks.

Reproducible: Didn't try

I'm not sure what you're asking about. Are you missing a feature in Net4j and want to know where to start if you want to implement it? Maybe you want to look at the source code for TCPAconnector, JVMConnector or HTTPConnector?

I am myself not clear on this, as i am  not deciding on those, but i was pointed out, if we are not using any of those network and we need chatty network, will it be problem ? ie with Teneo if we dont have the suggested networks or have networks other than the suggested ones, are we safe ?

What exactly is "those networks"?

> and we need chatty network, will it be problem ? 

What exactly is a "chatty network"?

> ie with Teneo 

You mean with the CDO HibernateStore that internally uses Teneo? That one does not affect the protocol between a CDO client and the CDO srever as it is only used on the server.

</persistence-mapping>


Above was the in the example.

I want to know

A) How to configure for the existing tables? Is there any Teneo configuration file, i have gone through wiki, but could not find means to configure it.

B) If it is inheritance, how to do that? As the below link , does not mention where to put it ?

http://wiki.eclipse.org/Teneo/Hibernate/ModelRelational/Teneo_Annotation_Examples#Inheritance_and_Discriminator_Annotations

C) Does Teneo store everything as String ? If so, do we need to have mapper class or some utility.

Thanks for patience and answers.

Hi,
Please ask these questions on the EMF newsgroup, I will answer them there. I am closing this issue as it does not seem to be a bug report but more questions on how to configure Teneo.
