Vince,

Thanks for your answer.

Yes, I understand, only when I checkout the program using subclipse,
the root of the project is trunk/h2/src/installer. I expected it to be
at trunk/ or something, because now I am unable to access the src
directory from the path mentioned. No problem in building, but I'm
interested in the source. I once managed to check out correctly. Going
to try again now!

Besides, what I mean by this is does H2 reserve at least SOME space
for buffering data at all? Cache size of 0 is of course not
preferable, but I want to have the effect of swapping buffer contents
to disk as soon as possible. Is there some lower limit on the cache
size? The amount of page transfers is very, very high. I expected it
to be high, but my own storage engine prototype (very simple one) uses
< 16K for buffering data from disk and generates a number of page
transfers orders of magnitude lower than H2 does, which surprises me a
little. All this still *assumes* the use of buffers each having a size
equal to the page size used and also *assumes* that the paging model
from database theory is used, which I am not able to figure out yet.
