SuoNayi commented on AMQ-3654:
------------------------------
I guess When the master loose the network connection to the database,the
underlying jdbc connection can not detect the network connection is broken in
time.
You can try to set the value of property lockKeepAlivePeriod of
jdbcPersistenceAdapter to be smaller than default value(default 30s).
If it works please let me know,thanks.

> Project: ActiveMQ
> Issue Type: Bug
> Affects Versions: 5.5.0
> Environment: Unix/Redhat 5.6
> ActiveMQ 5.5.0
> Oracle 10G
> Reporter: Richard Martin
> Priority: Critical
> Fix For: 5.6.0

>
> Our configuration is JDBC Master/Slave with one master and one slave. When
> the master is started, he acquire the database lock.
> Then when the slave is started, he wait to acquire the database lock. When
> the master loose the network connection to the database, the lock in the
> database is not removed and the slave connot acquire the database lock. In
> this situation, the master is unable to respond to client (due to network
> failure)
> and the slave is not started because he can't acquire the database lock.
> When the master is killed, the slave can't acquire the database lock too.
> After the network connection is restored, when the master starts, it cannot
> acquire lock to the database (because the lod lock is always present) so now,
> we have two slaves and no master.
> Please, refer to this issue which is the same problem : AMQ-1958
