Boris Belovic commented on TEIID-1451:
--------------------------------------
Hello Steven,
what were the fixes you made? I tried to repeat my experiment with new ER9 bits (should contain your changes), the client show better behaviour. Now it does not fail and continues in retrieving data from VDB. So I guess it reconnects to an active node. Although, there is still this message in the server log:
Processing exception 'The specified session ID "+0ombDj6Lu1q" is invalid. It cannot be found in the userbase.' for session null.
I tried this two times and during both tries I killed each node two times.

> I tried to simulate failover with Teiid. I have two SOA-P (ER7 build) nodes. When I killed first node, client correctly switched to second node. Then I re-started first node and killed second node. Client failed with the exception and did not switch back to first node.
> Client was very simple - querying VDB in infinite loop and printing result to stdout.
> What I did was:
> 1) I started both nodes, the started a client
> 2) Killed node no.1 with 'CTRL+Z' and 'kill -9 %1'
> 3) Client switched to node2
> 4) Re-started node no.1
> 5)Killed node no2 with 'CTRL+Z' and 'kill -9 %1'
> 6)Client failed with exception:
> 1 [InvalidSessionException]The specified session ID "null" is invalid. It cannot be found in the userbase.
