A brilliant solution.
I knew that the "real" Steve Adams couldn't
have edited it when I say the line starting:
<quote>
Latches are low-level queuing mechanisms
<end quote>
The man who wrote THE book about latches in
Oracle couldn't possibly have made the mistake
of thinking that latching was a queueing mechanism.
In fact, there is a bit in Steve's chapter on latches
which says quite specifically:
"....latches do not support request queueing....
latch requests are not necessarily serviced in
order."
Having said that, I thought the article was far better
than usual. There was still plenty of scope for
criticism, but it seemed to convey more useful
information than usual, even though presentation
and ordering were somewhat garbled in places, and
there were several small errors and misunderstandings.

Undskyld!
But you assumed that the Steve Adams mentioned at the bottom of that
article is the one you know ;))
They should have mentioned Steve's Web site. They did not miss tusc
and ioug URLs. Ummm..... wonder why not ;) ;)
I say poor Copy Editing on part of the publishers.
