Re: Do your have any DIVA problems?

Akos,

I have to say we have fewer problems with DiVa version4.0 than we had 
previously.  For one thing, we no longer lose data which is a step 
forward.  We do still experience the occasional "freeze" and if our 
experiments are too big it takes a long time to close one experiment 
and open another.  A "find experiment" can take up to 10 minutes, 
leading the impatient operator to assume the program has frozen and to 
do a hard exit and a full shutdown and restart.

However the fact that the program is Java has nothing whatever to do 
with these performance issues.	Java just happens to be the language 
used by the programmers.  No-one has ever shown the machine code from a 
Java compilation to be grossly inferior to that from any other 
language.  As for your error messages, Java is only reporting the 
errors that have arisen from programming mistakes.  Don't kill the 
messenger.

It may well be that the problems lie in the overall program design.  It 
is my suspicion (of course we can all have our suspicions) that, in 
order to have everything accessible, the program attempts to keep too 
much in memory (hence the 2GB supplied in the standard hardware).

I do think it is necessary to report such problems to BD.  Their test 
environments cannot hope to duplicate the conditions extant in all 
working flow laboratories.
