最新的Oracle Exadata Database Machine and Cloud Service 2017 Implementation Essentials - 1z1-338免費考試真題
問題1
Storage indexes are unique to 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 1 MB storage regions.
2 . cellsrv checks the high and low values, and determines that the storage region does not contain any values that meet 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. The MYOBJ_STATE'S region index is populated with high and low values for the OBJECT_ID column during the l/O request.
