<strong>EMC</strong> SnapView SnapView is a storage-system-based software application that allows you to create a<br />
copy of a LUN <strong>by</strong> using either clones or snapshots. A clone is an actual copy of a<br />
LUN <strong>and</strong> takes time to create, depending on the size of the source LUN. A snapshot<br />
is a virtual point-in-time copy of a LUN <strong>and</strong> takes only seconds to create. SnapView<br />
has the following important benefits:<br />
• Allows full access to a point-in-time copy of your production data with modest<br />
impact on per<strong>for</strong>mance <strong>and</strong> without modifying the actual production data.<br />
• For decision support or revision testing, provides a coherent, readable <strong>and</strong><br />
writeable copy of real production data.<br />
• For backup, practically eliminates the time that production data spends offline or in<br />
hot backup mode, <strong>and</strong> it offloads the backup overhead from the production server<br />
to another server.<br />
• Provides a consistent replica across a set of LUNs. You can do this <strong>by</strong> per<strong>for</strong>ming<br />
a consistent fracture, which is a fracture of more than one clone at the same time,<br />
or a fracture that you create when starting a session in consistent mode.<br />
• Provides instantaneous data recovery if the source LUN becomes corrupt. You can<br />
per<strong>for</strong>m a recovery operation on a clone <strong>by</strong> initiating a reverse synchronization <strong>and</strong><br />
on a snapshot session <strong>by</strong> initiating a rollback operation.<br />
<strong>Oracle</strong><br />
Database <strong>11g</strong><br />
Enterprise<br />
Edition<br />
<strong>Oracle</strong> Database <strong>11g</strong> Enterprise Edition delivers industry-leading per<strong>for</strong>mance,<br />
scalability, security, <strong>and</strong> reliability on a choice of clustered or single servers running<br />
Windows, Linux, <strong>and</strong> UNIX. It provides comprehensive features to easily manage the<br />
most dem<strong>and</strong>ing transaction processing, business intelligence, <strong>and</strong> content<br />
management applications.<br />
<strong>Oracle</strong> Database <strong>11g</strong> Enterprise Edition comes with a wide range of options to help<br />
grow your business <strong>and</strong> meet users' per<strong>for</strong>mance, security, <strong>and</strong> availability service<br />
level expectations.<br />
<strong>Oracle</strong> Database <strong>11g</strong> RAC<br />
<strong>Oracle</strong> Real Application Clusters (RAC) is an optional feature of <strong>Oracle</strong> Database<br />
<strong>11g</strong> Enterprise Edition. <strong>Oracle</strong> RAC supports the transparent deployment of a single<br />
database across a cluster of servers, providing fault tolerance from hardware failures<br />
or planned outages. If a node in the cluster fails, <strong>Oracle</strong> continues running on the<br />
remaining nodes. If more processing power is needed, you can add new nodes to<br />
the cluster to provide horizontal scaling.<br />
<strong>Oracle</strong> RAC supports mainstream business applications of all kinds, including Online<br />
Transaction Processing (<strong>OLTP</strong>) <strong>and</strong> Decision Support System (DSS).<br />
<strong>Oracle</strong> ASM<br />
<strong>Oracle</strong> Automatic Storage Management (ASM) is an integrated database filesystem<br />
<strong>and</strong> disk manager that reduces the complexity of managing the storage <strong>for</strong> the<br />
database. The ASM filesystem <strong>and</strong> volume management capabilities are built into<br />
the <strong>Oracle</strong> database kernel.<br />
In addition to providing per<strong>for</strong>mance <strong>and</strong> reliability benefits, ASM can also increase<br />
database availability because disks can be added or removed without shutting down<br />
the database. ASM automatically rebalances the database files across an ASM<br />
diskgroup after disks have been added or removed.<br />
