RE: MVC Architecture and transactions

From: Walden H. Leverich

However, I do have to disagree with your performance comment. Does
journaling add overhead? Sure. Does it add significant overhead? Not
really. Are there statistical outlayers? Sure, by the vast majority of
installations will see no significant difference between journaled and
non-journaled updates.

I wasn't complaining so much about performance (although I don't like ANY
unnecessary performance hits, because they add up), but about the additional
disk space and even more the management required to handle the journal
receivers. Neither of these is a good thing: extra disk space on a System i
is never cheap, and managing journals can really be a pain.

And if you do all of this to be able to gracefully restore after a system
bus outage, then I question the ROI. And that should be the final decision
point, as it is with any insurance policy: is the expense worth the
coverage?
