Oracle Exadata Database Machine delivers extreme performance for Data Warehousing and OLTP workloads, It also provides the 'petabyte scalability' required to cost effectively manage the sheer volume of data collected and stored by enterprise customers.
Read how these customers address 'petabyte scalability' with Oracle Exadata Database Machine in their environments:
Turkcell manages 100 terabytes of compressed data—that's a whopping petabyte of uncompressed raw data—on Oracle Exadata. When combined with the analytics capabilities of Oracle Advanced Analytics, they can now complete antifraud analysis for large amounts of call-data records in just a few hours.
SK Telecom became the first mobile communications operator in Korea to
introduce rate plans with unlimited data usage. This led to a large
increase in data volumes and, as a result, the company’s data analysis
and verification processes became more complex. On average 40 billion
transactions are processed each day on Oracle Exadata Database Machine enabling the company to store 1 petabyte of raw
data. Now they can provide detailed, accurate information about their customers’ roaming
data usage while ensuring high availability and performance to support billions of transactions a day.

MetLife, a leading global provider of insurance, annuities and employee benefits, has been an Oracle customer and user for many years, and uses Oracle technology for many of its mission-critical applications. On top of the Oracle Database, they deployed business applications from Oracle such as PeopleSoft, Enterprise Performance Management solutions, and OBIEE.
For failover scenarios, MetLife deployed Oracle Data Guard a while back, and soon realized that with new capabilities introduced with Oracle Active Data Guard, internal global reporting functionality can easily be improved by generating reports from the open, and otherwise idle, standby database.
To increase internal resource utilization even more, MetLife made the decision to use Oracle Advanced Compression, that reduced disk space considerably for archiving requirements and production systems alike. In production environments, the savings were even multiplied as it also reduced the amount of data that gets shipped over the wire to, and stored at, every standby database.
Watch Margaret Maglione, Director of Oracle Implementation, explain how her team realized just that:

Listen to this recently recorded podcast to
hear Nick Wagner from Oracle GoldenGate product management team, and Joe
Meeks from Oracle Database product management team discuss how to use
GoldenGate for maximum availability and the new features of GoldenGate
11gR2 that strengthen its high availability solutions.
This podcast is a little recap of the great live webcast we hosted back in December 2012. In case you missed it, make sure to watch it on demand, at your convenience.
Great questions were asked during that webcast, and our expert Joe Meeks was able to answer plenty of them. Here are some great examples of that:
Q: What is the difference between the logical standby and GoldenGate ?
Joe: Data Guard logical standby (SQL Apply) is an included feature of Oracle Enterprise Edition. It utilizes all of the same transport and role management features used by Data Guard Redo Apply (physical standby database), but it uses SQL to apply changes to a standby database that is open read-write (physical standby uses media recovery). The focus SQL Apply is as a feature of Data Guard for database rolling upgrades. The process begins with a primary and Data Guard physical standby. The standby is converted to a logical and upgraded. Production is then switched to the standby and the original primary (now a standby) is upgraded. From 11g onward we use the Transient Logical Rolling Upgrade Process - this results in the upgrade concluding with a primary and physical standby both at the new version. SQL Apply is only used for replication across version
GoldenGate is our comprehensive logical replication product. It is meant to address all advance replication needs and is the preferred solution for requirements such as reporting offload where the target database must be open read-write, bi-directional and multi-master replication, zero downtime upgrades/migrations, data integration, etc.
Q: What is it that Oracle Data Guard can do that Oracle GoldenGate can't ?
Joe: This is a backward way of asking this question . GoldenGate is a comprehensive, feature rich replication product. It can do many things Oracle Data Guard can't.
Data Guard is very focused - simple physical replication. Unlike GoldenGate, it maintains an exact physical replica of the primary (backups are interchangeable), it has no datatype or other restrictions to consider, it uses standard Oracle Media Recovery so has very high performance for all workkloads, it has advanced corruption protection - lost-write protection and automatic block repair. It offers both Synchronous (a guarantee of zero data loss) and Asynchronous replication.
Data Guard's primary goal is to provide the simplest, fastest, most complete data protection for Oracle Database, period.
GoldenGates primary goal is to provide the most feature-rich replication solution for the broadest possible range of requirements.
My recommendation is to first understand your requirements and preferences, then chose the right tool for that job.
Q: How can we use the new DBFS in conjunction with Oracle Data Guard and GoldenGate ?
Joe: DBFS is useful in a GoldenGate configuration to store the GoldenGate trail files and checkpoint files in DBFS to provide recoverability and failover capabilities in the event of a system failure. Using DBFS is fundamental to the continuing availability of the checkpoint and trail files in the event of a node failure. Ensuring the availability of the checkpoint files is essential to ensure that, after a failure occurs, the Extract process can continue mining from the last known archived redo log file position and Replicat processes can start applying from the same trail file position before a failure occurred. Using DBFS allows one of the surviving database instances to be the source of an Extract process or destination for the Replicat processes.
From a Data Guard perspective - anything that is in DBFS is protected just as any other database data is protected. So DBFS provides a way to have Data Guard protect file system content for you as well that would otherwise be external to the Oracle database.

You can reduce storage costs AND improve performance when you choose Oracle’s approach to managing data growth. Read how Information
Processing Center reduced their operational database resources by more than
400% using Oracle Advanced Compression. Likewise,
found that it increased the performance of its
PeopleSoft reporting environment by reducing the time to complete certain nightly
extracts from 12 hours to four. Deutsche
Börse AG used a combination of compression and partitioning to reduce their
storage requirements which had grown by 50% to 24 terabytes and achieve optimal performance by partitioning fact
tables with more than 1 terabyte. Health
Market Science also used this combination to manage data growth more cost effectively.
To learn how they did it, listen to Oracle Database expert Kevin Jernigan describe how to reduce your database storage footprint and costs.
Oracle's approach to managing data growth is just one of three compelling reasons to upgrade to Oracle Database 11g.
Have a happy and prosperous New Year!

Because your data is a critical business asset, you depend on having it complete, accurate and available 24x7. Below, I’ve highlighted some key assets we've developed to help you ensure maximum availability.
In 2012, we introduced the Calmest IT guy in the world video series. Watch him to see what it takes to keep business systems available, protect business data from downtime, eliminate idle redundancy of standby servers and recover quickly from human errors.
If any of these situations look familiar you’ll appreciate how these customers addressed their high availability challenges with Oracle Database Solutions. First meet BarrièrePoker.fr who can now guarantee 24/7 availability for their online gaming platform thanks to their high-performance, scalable transactional platform with Oracle Real Application Clusters and Oracle Active Data Guard replication services that eliminated idle redundancy in their standby database environment to better serve their 10,000 players and responds 7x Faster. Or check out ForeSee who used Oracle Active Data Guard for disaster recovery across their data centers to support data growth with a high performance clustered solution or Hospital de Clínicas de Porto Alegre who created a complete contingency IT infrastructure to ensure security of their hospital records with Oracle Active Data Guard.
To learn how to deploy a highly available infrastructure in your environment, listen to Tom Kyte describe Oracle Maximum Availability Architecture best practices or Joe Meeks drill down on disaster recovery. Use can use these simple tools to help you assess your high availability infrastructure and calculate your cost of downtime.
However, to take advantage of many of these great capabilities you will need to upgrade to Oracle Database 11g. So let me end here to wish you a happy and prosperous new year with three compelling reasons to upgrade to Oracle Database 11g with Roy Swonger

Unplanned outages and downtime still result not only in major productivity losses, but also major financial losses. Along the same lines, if zero planned downtime and zero data loss are key to your IT environment and your business requirements, planning for those becomes very important, all while balancing between performance, high availability, and cost.
Oracle Database High Availability technologies will help you achieve these mission-critical goals, and are reflected in Oracle's best practices offerings of the Maximum Availability Architecture, or MAA.
We created three neat, short videos showcasing some typical use cases, and highlighting three important components (amongst many more) of MAA:
