Hi all, Seems to me the system was obviously not correctly tested i.e. I'm sure that it was tested, but obviously the testing was not adequately designed/practised. If testing had been properly performed, design flaws would have shown up. Both of the above point to a lack of technical skills/project management - not necessarily java or DBA. Could be network or a number of other things, couldn't it? Couple of things I did discover: - The eNATIS site was very excited when they handled 12 transactions per second. - On 18 April they had 1 DB Server. That night they added second server. - Over the next few weeks they added a third, and then a fourth which was more powerful than the other 3 put together (makes you wonder what the first one was!) I might be missing something here, but the impression I have is that the flaws in the system are so fundamental, that the the system (which has been in development since 2001/2) cannot be "fixed". It seems like a "complete re-write" is the solution....;-)...perhaps the CT-JUG could take it on as a little project ;-). My 2 cents, Bruce PS: shortly before this topic began in this forum, I had been reading about eNatis and came across this blog which I found quite entertaining: HYPERLINK "http://dotnet.org.za/codingsanity/archive/2007/04/23/enatis-performance.aspx"http://dotnet.org.za/codingsanity/archive/2007/04/23/enatis-performance.aspx

It strikes me that the two most likely scenarios for this clusterfrack are 1) Poor database design and a critical lack of DBA skills 2) Poor understanding of the needs of a high transaction volume system. I'm mentally ranking them in order [2, 1], myself. The fact that they're going on about needing more server capacity makes me believe they've got a very inefficient design in place.
