NEW QUESTION 159
Which four actions are possible during an Online Datafile Move operation?

A. Flashing back the database
B. Performing Block Media Recovery for a data block in the datafile being moved
C. Executing DML statements on objects stored in the datafile being moved
D. Creating and dropping tables in the datafile being moved
E. Querying tables in the datafile being moved
F. Performing file shrink of the data file being moved

Answer: A,C,D,E

Explanation:
Explanation
"The good news is that Oracle 12cR1 now offers the ability to move entire datafiles between different storage locations without ever having to take the datafiles offline. The datafiles being moved remain completely accessible to applications in almost all situations, including querying against or performing DML and DDL operations against existing objects, creating new objects, and even rebuilding indexes online. Online Move Datafile (OMD) also makes it possible to migrate a datafile between non-ASM and ASM storage (or vice-versa) while maintaining transparent application access to that datafile's underlying database objects.
OMD is completely compatible with online block media recovery, the automatic extension of a datafile, the modification of a tablespace between READ WRITE and READ ONLY mode, and it even permits backup operations to continue against any datafiles that are being moved via this feature." References:

The threshold for activating tiering policies is based on two parameters:
TBS PERCENT USED
TBS PERCENT FREE
Both values can be controlled by the DBMS_ILM_ADMIN package.
TBS PERCENT USED and TBS PERCENT FREE default to 85 and 25, respectively. Hence, whenever the source tablespace's usage percentage goes beyond 85 percent, any tiering policy specified on its objects will be executed and objects will be moved to the target tablespace until the source tablespace becomes at least 25 percent free. Note that it is possible to add a custom condition to tiering policies to enable movement of data based on conditions other than how full the tablespace is.
In addition, the READ ONLY option must be explicitly specified for the target tablespace.

Which three statements are true about unplugging a pluggable database (PDB)?

A. The unplugged PDB becomes a non-CDB.
B. The unplugged PDB can be plugged into another CDB.
C. The unplugged PDB can be plugged into the same multitenant container database (CDB)
D. The PDB must be dosed.
E. The PDB must be open in read only mode.
F. The PDB data files are automatically removed from disk.

Answer: B,C,D

Explanation:
B, not A: The PDB must be closed before unplugging it.
D: An unplugged PDB contains data dictionary tables, and some of the columns in these encode information in an endianness-sensitive way. There is no supported way to handle the conversion of such columns automatically. This means, quite simply, that an unplugged PDB cannot be moved across an endianness difference.
E (not F): To exploit the new unplug/plug paradigm for patching the Oracle version most effectively, the source and destination CDBs should share a filesystem so that the PDB's datafiles can remain in place.
