Hello,

In RAC environnement, after IO Calibration, is the value 'MAX_MBPS' of 'DBA_RSRC_IO_CALIBRATE' view represent maximum of all instances (sum of each instance's maximum) or the maximum of one of all instance?

Oracle documentation :

MAX_MBPSNUMBER Maximum megabytes per second of maximum-sized read requests that can be sustained

Regards,

Thomas.
