Our setup is: Glassfish version 3.1.2.2 - 1. DAS and instance-1 running on
the same machine, while instance-2 is running on another machine in the same
network as config node. 2. We have set up transaction logging in a shared
directory as per the Glassfish High Availability Guide:
http://docs.oracle.com/cd/E18930_01/html/821-2416/gjjpy.html#gaxim 3. We are
using unicast configuration for cluster communication since we have Network
Load Balancer running in multicast mode in the network. 4. Our application
(.ear containing multiple .war) has 2 persistent timers (since we need only
one timer instance per timer at a time in the cluster). When instance-1 (or
instance-2) is shut down normally, the other instance recovers up the timers
from the shut-down instance as expected. When instance-2 crashes or goes
offline abnormally, instance-1 recovers its timers (again, as expected). But
when instance-1 crashes, instance-2 does not seem to recover its timers as
expected. As far as I can see from the logs, instance-2 receives proper
failover message for instance-1 and starts the recovery, but finishes it
without recovering any transactions or timers for the failed instance. Can
anyone tell me what the problem can be? (Should I provide any more
information?)
