ActiveMQ has a pluggable storage mechanism - and the ability to sync
to disk for every write is usually a property of the Store used by
the broker. For amq 5.0 - the default store is the amq store -
where the property is syncOnWrite, default is off.

Tibco has a configuration to mark a queue "fail safe". This means the

down, no
message is lost. This is described as the most "reliable mode".
Is there an equivalent to this in ActiveMQ?
Tibco also has a "non fail safe" mode for the queues which means
it does
not synchronously write to the disk. On other words, some kind of
buffering is done by the writer. "Non fail safe" mode performs far
better
than "fail safe" because of the synchronous write.
thanks in advance.
