Physical Reads |
Physical Reads shows the rate (in reads/s) of physical reads by the specified services for the Oracle RAC cluster. A physical read occurs when a database instance retrieves data from datafiles on the shared disk subsystem, and occurs every time a logical read fails to find the requested page in local or global cache. |
