Where Can One Find I/o Statistics Per Table? |
|
Answer» The UTLESTAT REPORT shows I/O per tablespace but ONE cannot see what tables in the tablespace has the most I/O. The $ORACLE_HOME/rdbms/admin/catio.sql script CREATES a sample_io procedure and table to GATHER the required information. After executing the procedure, one can do a simple SELECT * FROM io_per_object; to extract the required information. For more DETAILS, look at the header comments in the $ORACLE_ HOME/ rdbms/admin/catio.sql script.
