In the last case, what was done is that the network was disconnected from the active node until Oracle timed out the connection and the lock was released. Once the network was reconnected, the failed node began processing with the new node in parallel. I'm only reporting what was shared with me. I'm not certain of what was seen.
I'm looking for advice from anyone who is comfortable that they have a HA solution that is working for them and asking what method they used. ================== Now what about the last scenario. How was ActiveMQ shut down? How did was is restarted? How did you test that the restarted instance was actually processing messages? -Clark Our problem with using Oracle was that if the Active or Hot instance were to become disconnected and with the changes made to Oracle to timeout the connection and therefore release the lock on the database were to succeed, we would indeed have a secondary or standby instance begin processing and all is well until the previous instance again returns to the network and what we are finding is that it will again create a session with Oracle and will begin processing in parallel without attempting to gain a lock on the DB. Now we have a problem of two instances of ActiveMQ are running. Any advice on the best method? -- View this message in context: http://old.nabble.com/Noob-Questions---Fail-over---Redundancy-Help.-tp29057308p29216328.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
