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

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.
