Yes, it is supposed to execute again the queries found in the recovery log. So after enabling the failed backend, it should be identical to the active one. What is the difference between your two backends? Can you provide a self contained test case so that we can try to reproduce your problem? The database contains only one table holding 2 columns: an ID and a field of type bigint which corresponds to a counter. There's always one record in the database, the clients only increment the counter in this record. I use Hibernate 3 to do this. The sequoia client is also a CORBA server which manages data. clients send request to this server which updates data in the database (increment counter). When I stopped the mysql service on one host, counter on this database was 158. When I stopped request from clients it was 215 on the second backend. After re-enabling the failed backend each databases remained in the same state even if recovery seemed successfull. Does the fact that each VDB maintains only one backend can affect the result. I mean that as the first controller is discarded from the list of available controllers, its recovery log may not be maintained up to date ?? If you execute show controllers in a console, you can see both controllers?
