Orion is an IO performance testing tool provided by Oracle. It does not need to install oracle database software or create database to run this tool. It can simulate the IO load of oracle database, and it can also be used to simulate the striping function of ASM.

After downloading, decompression can be used directly.

Write the device to be tested into a file on the same path, and then test it.
