What is the Orion I/O Test Tool? (Doc ID 1905698.1)

SOLUTION

Here is the definition of it from the Oracle® Database Performance Tuning Guide
11g Release 2 (11.2) section 8.4.1 Introduction to the Oracle Orion Calibration Tool:

Oracle Orion is a tool for predicting the performance of an Oracle database without having to install Oracle or create a database. Unlike other I/O calibration tools, Oracle Orion is expressly designed for simulating Oracle database I/O workloads using the same I/O software stack as Oracle. Orion can also simulate the effect of striping performed by Oracle Automatic Storage Management.

 To clarify this further the ORION Oracle I/O test tool is used to calibrate luns. It is not used for filesystem performance. If you database is created on OS filesystem then you can use PL/SQL API DBMS_RESOURCE_MANAGER.CALIBRATE_IO. If you are trying to calibrate your filesystem then please contact your filesystem OS vendor for assistance.

For more information on how to run the tool please see the instructions in Oracle® Database Performance Tuning Guide
11g Release 2 (11.2) section 8.4.2 Getting Started with Orion.

The Orion I/O Tool starting with 11.2 now is available in the RAC installation under the ORACLE_HOME/bin.
