Brandon Allen posted in Nov 2005 and I copy his post below. I don't think it answers your question but the thraed may hold other answers and Brandon may be able to assit as well
I checked the list archives at http://www.freelists.org/webpage/oracle-l

When you have resolved it why not post the solution

Here is a repeat of a post I made back in November 2005 - in case anyone is having trouble getting it to work on Windows. I haven't checked lately,
but at the time, it wasn't clearly documented. In retrospect, maybe it should have been more obvious to me that I had to specify a datafile, but it
wasn't obvious at the time:

In case anyone else wants to use ORION on Windows, I finally figured out
how to get it to work. Apparently you have to specify an actual Oracle datafile, not just a directory or empty text file. I put "C:\oracle\oradata\orcl\example01.dbf" in my mytest.lun file, and then ORION worked, giving me the following command-line output: C:\Program Files\Oracle\Orion>orion -run simple -testname mytest
-num_disks 1

ORION: ORacle IO Numbers -- Version 10.2.0.1.0 Test will take approximately 9 minutes
Larger caches may take longer

And the following results in mytest_summary.txt: ORION VERSION 10.2.0.1.0
Commandline:
-run simple -testname mytest -num_disks 1
This maps to this test:
Test: mytest
Small IO size: 8 KB
Large IO size: 1024 KB
IO Types: Small Random IOs, Large Random IOs Simulated Array Type: CONCAT
Write: 0%
Cache Size: Not Entered
Duration for each Data Point: 60 seconds

Small Columns:,      0
Large Columns:,      0,      1,      2

Total Data Points: 8
Name: C:\oracle\oradata\orcl\example01.dbf Size: 157294592 1 FILEs found.
Maximum Large MBPS=9.01 @ Small=0 and Large=2 Maximum Small IOPS=52 @ Small=2 and Large=0 Minimum Small Latency=20.45 @ Small=1 and Large=0

Good evening

I am going to setup ORION(Oracle I/O Numbers Calibration Tool) on my new Linux server to test disk I/O of my database server. I am so confused the setup procedures in the User Guide. Did anyone work on ORION before and would be able to help me answer the questions that I have?

In the User Guide, it said that ORION test is completely dependent on asyn I/O, so the library libaio needs to be in one of the standard lib directory or accessible through the shell env library path variable (LD_LIBRARY_PATH or LIBPATH). How can I meet this requirement? I checked the Liunx box, there is libaio rpm installed.

# rpm -qa libaio
libaio-0.3.96-5

2. Do I must create mytest.lun file and use this name for the value of
-testname during the test?

3. What does physical spindles mean? This is the value that need to be passed to -num_disks parameter.

Many thanks for all the help and happy Thanksgiving. Cindy
