[Mulgara-general] Memory error during rdf load

[Paul Gearon]

Hi Bill,

Well, the obvious answer is to go to 64 bit, but if you're really
against that then you can try a couple of things.

First off, does DMOZ have an N3 format? That has different memory
requirements while loading, so it may do better.

Another thing to try would be to set the heap size for Mulgara. That's
done with the -Xms (initial size) and -Xmx (maximum size) options on
the Java command line.

Finally, I'm working on some tweaks to indexing that will make loading
a little more efficient. However, I won't be done with this for a few
days yet, and it won't be in a formal release for nearly 2 weeks. But
if you can hang on, then this should help 32 bit installations.

Regards,
Paul Gearon
