You are calculating the storage capacity that your customer will require on their ZFS Backup Appliance. Identify the set of factors that will affect this calculation.
Which three migration options are available when you migrate a database from the Big Endian format system to Exadata?
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.
