You plan to use the In-Database Archiving feature of Oracle Database 12c, and store rows
that are inactive for over three months, in Hybrid Columnar Compressed (HCC) format.
Which three storage options support the use of HCC?
A.
ASM disk groups with ASM disks consisting of Exadata Grid Disks.
B.
ASM disk groups with ASM disks consisting of LUNS on any Storage Area Network array
C.
ASM disk groups with ASM disks consisting of any zero padded NFS-mounted files
D.
Database files stored in ZFS and accessed using conventional NFS mounts.
E.
Database files stored in ZFS and accessed using the Oracle Direct NFS feature
F.
Database files stored in any file system and accessed using the Oracle Direct NFS
feature
G.
ASM disk groups with ASM disks consisting of LUNs on Pillar Axiom Storage arrays
Explanation:
HCC requires the use of Oracle Storage – Exadata (A), Pillar Axiom (G) or Sun ZFS Storage
Appliance (ZFSSA).
Note:
* Hybrid Columnar Compression, initially only available on Exadata, has been extended to
support Pillar Axiom and Sun ZFS Storage Appliance (ZFSSA) storage when used with
Oracle Database Enterprise Edition 11.2.0.3 and above
* Oracle offers the ability to manage NFS using a feature called Oracle Direct NFS (dNFS).
Oracle Direct NFS implements NFS V3 protocol within the Oracle database kernel itself.
Oracle Direct NFS client overcomes many of the challenges associated with using NFS with
the Oracle Database with simple configuration, better performance than traditional NFS
clients, and offers consistent configuration across platforms.

This paper illustrates the implementation of Hybrid Columnar Compression (HCC) for Oracle Database
tables and partitions which reside on an Oracle ZFS Storage Appliance. It covers implementation of Hybrid
Columnar Compression on Oracle ZFS Storage Appliance-resident direct Network File System (dNFS)

In addition to Smart Compression, other ADO policy actions can include data movement to other storage tiers, including lower cost
storage tiers or storage tiers with other compression capabilities such as Hybrid Columnar Compression (HCC). HCC requires the use
of Oracle Storage – Exadata, Pillar Axiom or Sun ZFS Storage Appliance (ZFSSA).
