Home -> Community -> Mailing Lists -> Oracle-L -> RE: x$ tables info
Definitely, but JL is not very current, while Steve has an excellent free
newsletter
in addition to an awesome collection of scripts, tips and Q&A's.
If anybody on the planet understands the depths of Oracle better than Steve, I have not yet run across his works.

You can refer to either of these three... IMHO, these are the best...
1. Jonathan Lewis's site... http://www.jlcomp.demon.co.uk 2. Steve Adams's site - http://www.ixora.com.au 3. Oracle 8i Internal Services - Steve Adams
Thanks

Hi Stephane,
It shows buffer busy waits on buffers containing blocks from those
datafiles.
Make sure that your script offsets the file number by one when doing the
join to V$DATAFILE.
Have a look at my buffer_busy_waits.sql script for an example.
Also, for buffer busy waits against rollback segment header blocks,
my enough_rollback_segments.sql script makes a helpful distinction
between read waits and write waits
that might help you to work out what's going on there.
You may want to post the output of both scripts back to the list?
Regards,
Steve Adams

Hi,
I'm trying to understand x$kcbfwait.
I can't find a reference of this table in any V$
views.
I have a script that linked x$kcbfwait to v$datafile. It seems to show waits on datafiles but I do not quite understand what's going on. The datafiles having the more waits are the ones containing the rollback segments.
