Carsten,

this is one of our "long term" planning items. Because of shifting priorities this 
item has been postponed several times.

Regards,
Juergen

Juergen,

Thank you for this explanation. I can understand why you wanted to get rid 
of the distributed database code. Did you still leave some of it in place 
so that XA transaction coordination could some day be implemented?

Carsten

Hi Carsten,

it was the decision of the development, that moved to SAP, to drop all 
activity, which was related to distributed database management. At this 
point of time we faced severe performance problems caused by the approach 
to handle distributed update transactions on replicated data. This was 
caused by the synchronization of locks held on different nodes within a 
distributed database. On the other hand we had to focus on object 
management (liveCache). So we choose to decrease comlexity in our db 
kernel. And looking back this was a good decision (and I don't see any 
other systems having success with a full distributed approach according to 
Dates rules).


Regards,
Juergen Primsch
