Hi Arnaud,
I do not recommend the use of the ResultCache in general cases. Its
implementation is not production quality.
<ResultCache granularity="table" />
I will need some clarifications on the following.
Normal usage of the cluster is good. My databasses are consistent.
You mean that all databases see the updates when they are all enabled,
correct?
My test scenario : I shutdown my db #3. Controller #3 notice it.
Well, if you disable backend 3 on controller 3, all controllers should
create a checkpoint (you can see the list of checkpoints in expert mode
I think). If not, it means that you have a group communication problem.
Or did you try to shutdown the virtual database on controller 3? The
exact commands used would help diagnose the problem.
System is still running. I restart my database. I try to re enable my
backend (after a dump restore) ... no success. then I must restore
logs from another node. Then it's the end. The node suspend my vdb
activity ... no more after 20 mins.
This sounds like a group communication problem. The group communication
uses generally (if configured with UDP) both multicast to send message
and unicast for acknowledgments and other signaling messages. There
might be a problem there.
Keep us posted with your progress,
Emmanuel
