Good Suggestions from Norman - I would just add that you can also use the
standard, oracle-supplied binary - tkprof, or the more thorough, PL/SQL-based
TRCANLZR (Trace Analyzer - Metalink Note: 224270.1). I've never used orasrp,
but from the web page it looks like it doesn't run on AIX, however maybe you
can run it on your PC and just ftp the trace files down there for analysis.
You'll also want to make sure that max_dump_file_size is either unlimited or
bumped up high enough that you don't run out of room in your trace files, and
then monitor the filesystem to make sure you don't fill it up. Also, I'd
recommend to gather OS level stats every 1 minute during the test and log them
to a file for later analyzis, e.g. sar -d 60, sar 60, vmstat, iostat, etc.
There are a lot of documents on Metalink and elsewhere regarding tuning AIX for
Oracle so do some searches both on Metalink and Google. For example - Metalink
note: 245356.1 "Oracle 9i - AIX5L Installation Tips", and the following note
regarding Direct IO and Concurrent IO on AIX:

Statspack level 6 works for me.
