Subject Equivalent of Tibco EMS FailSafe
Date Thu, 20 Sep 2007 03:10:59 GMT

Tibco has a configuration to mark a queue "fail safe". This means the
messages for a "fail safe" queue is synchronously written to the disk. In
other words, no buffering is done for write (probably uses fsync --  that
gaurantees the data is flushed to the disk). If the server goes 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.
