ORION

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?

1. 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
