Storage indexes are unique to the Exadata Database Machine and their primary goal is to reduce the amount of I/O required to service I/O requests for Exadata Smart Scan. Put the following steps in order:
1.The Exadata cell services software conducts I/O requests on I MO storage regions.
2.cellsrv checks the high and low values, and determines the storage region does not contain any values meeting the predicate.
3.The database is started.
4.Physical I/O to the region is bypassed if the query selection falls outside the high/low storage index storage.
5.A query is issued against the MYOBJ_CTRL table that has a predicate OBJECT_ID=1500.
6.A subsequent query is Issued against the MYOBJ_CTRL table that has a predicate OBJECT_ID=2234.
7.MYOBJ_STATE'S region index is populated with high and low values for the OBJECT_ID column during the I/O request.
