I 'm very much looking forward to getting OITOTOT book
because I value the *methodology* provided by the
OakTable authors.
Wish someone would post if they got it yet from
Bookpool. :-)

As I 've stated earlier, I believe the OWI book is
mandatory study for DBAs regarding wait interface
(through 10g) tuning efforts. There are hundreds of
points made in the book which I can use (once I 've
tested them of course). ;-)
<OFF TOPIC to anyone who has already read the OWI
book >:
But, I have issues (editing and methodology) with the
OWI book that I did not have with the other two books
Mladen mentions.
I 'll give what I believe to be a quick OWI example of
an editing error. It is deep in the book, therefore
assuming someone has read the whole OWI book, and on
pg 201 regarding transactions:
"Introducing additional commits can create other
problems, among them, the infamous ORA-01555 (See ORA-01555.ora-code.com): snapshot
too old error because the rollback (or undo) data can
be overwritten ".
Please read the whole section in context. In my
opinion the sentence implies that 'shorter '
transactions are causing ORA-01555 (See ORA-01555.ora-code.com) errors. My belief
is that more commits implies 'shorter ' transactions.
Or, the converse, am I reading that if I make my
transactions 'longer ' (fewer commits) then there
should be fewer ORA-01555 (See ORA-01555.ora-code.com) errors. Please enlighten me
if I 'm missing an obvious point, but I don 't get the
point of this sentence. The remainder of the paragraph
is fine.
Further discussions of OWI probably deserves their own
thread, rather than hijaak OITOTOT.
