[CDO] id generation client side & raw replication [message #1005927]

Tue, 29 January 2013 05:31

Eclipse User

Hi,

We're running a small application which uses the master/clone mechanism. Our EMF model only holds one object named 'Person' with the attributes 'id', 'firstName' and 'lastName'. The property 'id' of the attribute 'id' holds the value 'true'. But when saving this id is always '0' in the database.

I thought when setting the property 'ID_GENERATION_LOCATION' to 'CLIENT', the id should be generated.. Or does this only apply to the attribute 'CDO_ID'? If that's true I should use that one I suppose..

We also have a problem when 'raw replication' is set to true. When starting the clone it keeps making new sessions with the message 'replication failed, retry in 2 seconds'. Shouldn't I use 'raw replication'?

Thanks in advance.

Regards,
Ricky

Yes ;-)

But not in normal replication mode? That's weird. I'd need more details about your problem to be able to judge.

> Shouldn't I use 'raw replication'?
Raw replication is the default now:

In normal replication there are no errors indeed.

I'm using your master/clone test code. What do you need to judge the problem?

I enabled tracing and this a part of the output:

CDORepositorySynchronizer [debug.repository] Connected to master.
CDORepositorySynchronizer [debug.repository] Synchronizing with master...

Hard to tell exactly. The exception that causes the log message would be a good start.

Is it possible that you add/commit new packages after the initial replication? Unfortunately that's not supported!

But there is no real exception, only the messages in the tracing log..

The first time I launch the application everything works fine. The second time the problem starts.. I'm launching the exact same code though.

Hmm.. I must have done something wrong because I copied your code again and now it works fine. My mistake..

Does that mean that this thread is "closed"? Good ;-)

Yes it is. How can I close the topic? I still have another problem but I will open a new topic for it. Thanks!
