You conned using SQL Plus to the root container of a multitenant container database (CDB) with SYSDBA privilege.
The CDB has several pluggable databases (PDBs) open in the read/write mode.
There are ongoing transactions in both the CDB and PDBs.
What happens alter issuing the SHUTDOWN TRANSACTIONAL statement?()
A. The shutdown proceeds immediately. The shutdown proceeds as soon as all transactions in the PDBs are either committed or rolledhack.
B. The shutdown proceeds as soon as all transactions in the CDB are either committed or rolled back.
C. The shutdown proceeds as soon as all transactions in both the CDB and PDBs are either committed or rolled back.
D. The statement results in an error because there are open PDBs.

A warehouse fact table in your Oracle 12c Database is range-partitioned by month and accessed frequently with queries that span multiple partitions The table has a local prefixed, range partitioned index.Some of these queries access very few rows in some partitions and all the rows in other partitions, but these queries still perform a full scan for all accessed partitions.This commonly occurs when the range of dates begins at the end of a month or ends close to the start of a month.You want an execution plan to be generated that uses indexed access when only a few rows are accessed from a segment, while still allowing full scans for segments where many rows are returned.Which three methods could transparently help to achieve this result?()
