Title: RE: What to check?
David,
I'd check that they are using the same exact script on all three machines.

Title: RE: What to check?
All three machines having the same amount of CPUs and memory, and he uses the same script to run on three machines, some of tables containing hundred thousands of records. Below is a portion of his script. Is there a way to improve his SQL command?

David,
Have you checked the most obvious... The number of rows in the table?
Also, you say three different Solaris8 machines... How different are
they? Are the disk subsystems the same on all three? How identical are
their configurations? How similar are the init.ora files on all three
David,
You need to see what is taking all the time on the 'slow' machine.
Ask the person with the script to put this at the top of the script
for the next run:
alter session set events '10046 trace name context forever, level 8';
Explanation of level:
-- level 4 is bind values
-- level 8 is
Are they dumping the table over the network or locally?
If it's over the network, then probably there is a slow network connection
or/and small array fetch.
Checking the number of fetches in a trace/tkprof file could help.
Also pre-compiled languages have many bugs that disable array fetch.

Alex,
Here's what I currently look for:
At the begging of a line ORA or TNS
Anywhere in the line 'crash' or 'recovery';
Sometimes generates more mail than I care for. :)
