Thanks, but I am _not_ looking for culprits ... and I will be collecting this data over a week so collecting traces is not an option. I have queries run by research dept that routinely scan millions of rows, multiple times a day ... EMC should be happy though ...  

Thanks again

Hello folks,

                Recently, I employed a similar approach in our test  
                database to figure out the problematic queries during
                a certain load test. I used a logon trigger with just 2 
                statements :
                                alter session set max_dump_file_size =
unlimited;
                                alter session set sql_trace = true;
 
                The init.ora had to be modified to set _public_trace_files =

                 true to allow the database userid used by the application
                 to be able to write to the user_dump_dest.
 
                 Regarding the specifics of the test, I coordinated with the

                 testers and created the trigger just before the load test 
                 began and dropped it after the test was over. Of course, I 
                 had to make sure that this load test was the only
application
                 running. There were around 90 trace files generated which
                 gave me much more information that I ever envisioned.
                 It showed that the connection pooling of the application 
                 was implemented poorly since 90 files were generated 
                during a 1 hour load test. Also, I consolidated all the
trace
                files into 1 huge trace file using a shell script and ran it
                through TKPROF. The information obtained was priceless.
                It not only provided the culprit queries, it also provided
the
                amount was time being spent in the database out of a total
                load test of 1 hour.
 
                Just wanted to share it with you folks.
                Let me know if you have any questions.
 
Anil

Raj,   

Assuming that these users will logoff normally (for the most cases), you could have a database level LOGOFF trigger that captures the following 'stats' from these sessions (out of v$MYSTAT):   

CPU used by this session (Cpu time used) user commits (Number of transactions - figuratively!) physical reads + physical reads (direct, lob, etc.) + db block changes (former is reads, latter is the number of changes that would cause writes on

behalf of that process for Log, Undo and DBFile) session pga/uga memory max (Memory usage) SQL*Net roundtrips to/from client and dblink (Network usage)   

Collect and summari! ze system wide (via STATSPACK) and for individual users

via LOGOFF just to compare.

Thanks Dennis,

I have periodic (10 mins) snapshots taken of following views ...

  1. gv$session
  2. gv$sesstat
  3. gv$transaction
  4. gv$sess_io
  5. gv$sysstat

Now, I really _can't_ use Statspack, because it tells me overall score. I need to compute the load put on system by a set list of users ... it is kind

of computation of possible charge back.

So, I have the underlying system stats. but I am having tough time to put them in perspective for management types. I'd like to show them %CPU usage, %IO load, %Memory being used ...

any ideas?
Raj

   I'll second Jared's idea. Don Burleson in his book Oracle9i High-Performance Tuning with STATSPACK makes a strong point that looking at system load must start with the underlying system. Any look at Oracle performance must begin with an understanding of what the system load was at that time. As Jared points out, the three components are CPU, I/O, and memory. For example, you may find that one of these target users is the high

CPU consumer from an Oracle perspective at a point in time. Now, if you discovered the system CPUs weren't being taxed at that time your conclusions

might be different than if you discovered the system CPUs were pegged at 100% at that time.

Load on a system is in general comprised of three components: CPU, memory and IO.

If you have something in place to track those on a per user basis, then you're doing well. You might consider also tracking other users, so that you have a basis for comparison.
