--------------------------------------------------------------
Since the ability (ejb) to failover relies on the client side(if im not mistaken), the
failover on a node crashing shouldnt be measurable or?
The client downloads the dp-object and handles it itsself, so will there be a measurable
"delay" if a servercrash occurs and it fails over to another node?
My test was to deploy an ejb on 3 nodes and send counting numbers to the cluster. Whenever
a node receives a number, it writes the receivment to the database whereas the database
adds a timestamp, so that the times wont change according to the server clocks.
So, whenever a failover occurs, there should be a measureable delay between No. X and Y,
just in case it causes some.
The result was, that theres (with nanosecs) actually none...
Did I understand anything wrong or does a measureable delay only occurs if theres anything
has to be restored from replicated data?
Thanks in advance,
