Hi
I'm looking for docs that explain tuning of SQL statements. But, no stories
about latches, buffers, TKPROF, blocks, V$ views... Just simple (or
advanced?) tips on:
- ordering of tables in FROM part of select (where goes the largest table,
and where to put the smallest table), and why is it
There are reorgs to fix fragmentations, and reorg to
reclaim dirty space. LMT's fix the former but not
necessarily the latter.
I do believe tho' that the days of unloading the
entire database and reloading it (with the exception
of changing the blocksize) should be a thing of the
past

Oracle Financials 11i asks for 14000 semaphores:
When I do the calculation as per the Oracle Guide I come to about 1000.
Anybody know why the disparate nature of these numbers. Can semaphores be

I can RTFM, but wonder what lists comments are before

That's the whole point Jared was trying to make: your
locking issue is because you *don't* have indexes on
your foreign keys.

Connor,
Reorgs to change the blocksize are reduced even
further in 9i since multiple blocksizes are allowed in
the same database, although you still can't change the
default blocksize without rebuilding.
The new free list allocation mechanism looks pretty
slick too.
Definitely lots of new

First of all, if you don't see cumulated waits for the 'latch free' event in
either v$system_event or v$session_event (for a specific session/job) there
is absolutely no need to do anything about these ratios. It's about the only
two latches mentioned in the reference books and it's about the
But each different block size requires its own buffer cache. If you haven't
configured the seperate buffer cache, you cannot add tablespaces with a
different block size to the database.

I'm a bit confused here. You say that you are going to tune your redo

have any redo allocation latch contention. The threshold to determine

Mogens,
You are right.
nothing is a performance problem unless there is a time contention.
In general, it's very hard to see time spent in each latch. itrprof SQL Analyzer
with waitgroup=(name,P1,P2) can report time spent in each latch. So, you can see
time spent in A latch, time spent in B
My theory is this.
A loosely used ratio for performance reviews.

(Bugs introduced in your code x 500))
But use this with a grain of salt as many things are involved in programming
and lines of codes, bugs, and number

Yes, it is okay to set it higher than this. It won't degrade the

either.

You might also want to test setting

By design, the CBO considers multiple starting tables

Thanks for the info. I was not aware what shmmax value
