In 11g you could use DBMS_RESOURCE_MANAGER.CALIBRATE_IO, similar to ORION, sort of built-in. It hasnt got as many options as ORION but you can use it for platforms which ORION is not available... As ORION, I have used 3 months ago and it works well. Thanks -- LSC On 9/15/07, ryan_gaffuri@xxxxxxxxxxx <ryan_gaffuri@xxxxxxxxxxx > wrote: It was recommended to us by Oracle to do benchmarking.
