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
Correct Answer: AEG
Explanation/Reference:
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.
