RE: How to merge 2 customers into 1?

This is not something to be taken lightly and without study.

Ahh, so that's why I've never done or even seen anyone do a commit or a
rollback. Is this something that is widely used elsewhere? I mean how
many rpg shops in 100 use journalling and cc?

It's fairly widely used - I would estimate that 50-75% of shops with
home-grown applications use commitment control, and significantly higher
off-the-shelf counts.

Don't get me wrong: It is absolutely worth it. I just didn't want anyone to
think that you could get there by flipping a couple of switches. The entire
application should originally be designed with commitment control in mind...
or the impact should be reviewed before implementing. You can try if you
like, but I wouldn't recommend it on a highly used production system.
