On Linux/Unix I would execute the following command:

strings $ORACLE_HOME/bin/oracle | grep -e "^SYS_OP_w*$" | sort -u

Thanks for the interesting paper.

It's nice that your paper comes out just when a lot of people might be wondering what a Bloom Filter is. Therefore it is timely in that sense. Well, not *just* a joke.

I've been aware of bloom filters for quite a while too but it's just funny that this should come out at a time when bloom filters happen to have been mentioned in the same week as they're mentioned in an important Oracle white paper. It was just a small joke really. I was laughing about the coincidence.

I'm aware of bloom filters in Oracle since December 2005. So, I wanted to write something about them for a long time. IIRC we also discussed about them at the 2006 UKOUG conference... Therefore, I'm really happy that this short paper is, at last, published. Cheers, Chris Hi Doug

Looks good so far but it'll probably end up half-read for a few months like all the books do. I have a course slides deadline approaching so it's back on the shelf for now .... Pretty timely, too! ;-) Page 14, here …
