ADDM advices Oracle's application logic
Date: Wed, 16 Jan 2008 06:37:46 -0800 (PST)
I'm new to performance tuning and linux , so any pointers to speed up my investigation is much appreciated.
I've just installed a 10.2.0.3 on a 64bit Linux AS. I created a few
TBS, with datafiles of 16GB each. The first file took about 3 minutes,
the last file took about 1 hour to create. My experience on other
machines is just a few minutes.
I'm looking at the ADDM advice:
"Individual database segments responsible for significant user I/O wait were found."
Investigate application logic involving I/O on database object with id 440.
where I_RLS2 is:
Name I_RLS2 Schema SYS Tablespace SYSTEM Index Type Normal Status VALID
Has anyone an idea what happened or where to look? What other elements are needed for a proper diagnoses? Again, i am alone on the machine, not other processes, users etc. Physical writing was the paramount i/o activity, as expected.
