Subject Re: Equivalent of Tibco EMS FailSafe
Date Fri, 21 Sep 2007 04:26:58 GMT
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.
