Session Abstract
Are database refresh challenges causing you to miss projects deadlines? Is your storage
cost for dev/test environments spiraling out of control? In this session, you will learn how
the Snap Clone feature of Oracle Cloud Management Pack for Oracle Database
• Can refresh production databases after masking and subsetting
• Can enable instant cloning of large databases (TBs) while saving more than 90 percent
on storage costs
• Fits perfectly with your existing investments in storage, servers, and engineered systems
• Is being used by other customers for large-scale environments

Snap Clone using Solaris File System (ZFS)
• Uses a single stock Solaris 11.1+ image – physical or virtual [and NOT the
Sun ZS3 Appliance ]
• Supports any kind of storage – NAS or SAN
• For SAN, mount luns as raw disk and format with ZFS filesystem
• Does NOT require the snapshot/clone licenses from the storage vendor,
these features are available for free
• Additional features include compression, deduplication, IO caching, etc
• HA has to be handled externally either via Solaris Clusters, or by using HA
features of the underlying hypervisor

Solaris File System with SAN Storage Network Diagram

• Ability to create thin databases from
RMAN image copies
• Uses NFS v3 client embedded in
database
• Supported configurations
– Single instance databases
– Note: Only file system support for this
setup (No ASM)
• Supported Versions: 11.2.0.3+, 12.1
• Advantages
– Easy to setup
– No special storage software needed
– Works on all platforms
– Time efficient: Instantaneous cloning
– Space efficient: Create multiple clones
based on one backup
– Uses dNFS to improve performance,
high availability, and scalability of NFS
storage
CloneDB using DNFS

NAS Network Diagram
• Components:
• NAS storage
• Ethernet switch
• DB servers
• EM 12c
• Storage proxy host
(Agent managed
host)

Snap Clone on ASM + EMC Storage
• Ability to create ‘live’ thin clones of
databases on ASM
• Live Clone: NOT snapshot based, but
a live clone of DB
• Clone can be within the same or on
a different cluster
• EMC VMAX (with Time Finder
VPSnap) and VNX storage appliances
• Supported configurations: SI and
RAC
• Supported Versions: DB = 10.2.0.5 or
higher; GI = 11.2 and higher

Enable direct clones from production databases Works with patched or upgraded binary• Enable direct clones from production databases
• Provide automation to refresh the clone with data
changes in production
• Works for storage snapshots, RMAN backups, data
pump exports, etc
• Includes masking & subsetting
• Works with patched or upgraded binary
• If using clone as test master, allows self service users to
refresh existing clones with new data
• Reduces administrative overhead
