Gosh, I was hoping I didn't have to get into that.

Does anyone have an updated script working?

Hey all,

I've just tried running a slightly modified version of:

http://www.ixora.com.au/scripts/sql/response_time_breakdown.sql

...on our month-old 9.2.0.5.0 instance on HP/UX 11i (I added "jobq slave =
waits" to the list of idle waits from d.kslednam).  However, it's =
telling me that our queries have waited 55 *years* for db file =
sequential read.  I know we need to reduce our I/O, but come on!

I've looked on MetaLink for bugs/notes/articles and in some archives, =
but nothing really pops up.  I vaguely remember mention of UOM changes =
(seconds/centiseconds/etc) in some version of Oracle's internals, but I =
couldn't find anything on that either.

I know Mr. Adams has not been able to update his site for 9i/10g, but I =
was hoping to check this out after our 9i upgrade.  (I know, I know.  =
It's not a Method R query.  We're not there just yet...)

TIA,
Rich
