What Comes Next After You Decide on Using Oracle Exadata

As Oracle Exadata continues to expand its footprint for both transaction and analytical processing, moving existing systems to Exadata and feeding it with enterprise data on an ongoing basis have become important discussion topics for Exadata customers. Consolidation and migration is the first step of this powerful journey with Exadata, and I'd like to start there in today's blog post.   

The systems that benefit from Exadata's extreme performance and reliability are typically business-critical systems that carry major risks when it comes to migration. Any downtime or data loss can have significant impact to the business in terms of revenue generation, customer loyalty, and productivity. As Oracle GoldenGate user community knows well, GoldenGate's heteregenous, real-time, and bidirectional replication capabilities enable very strong zero downtime migration and consolidation solutions for major databases and platforms including Oracle, IBM DB2 (zOS, iSeries, and LUW), HP NonStop, SQL Server, Sybase ASE, MySQL, and Teradata.

We discussed GoldenGate's zero downtime migration to Exadata offering and best practices with our customer IQNavigator in a webcast that is now available on demand:

Zero-Downtime Migration to Oracle Exadata Using Oracle GoldenGate: A Customer Case Study

If you have not watched it, I highly recommend listening to the discussion, as it clearly explains there should be no concerns around causing business interruption when moving to Oracle Exadata using GoldenGate.  GoldenGate's failback option to the old environment is a great tool for minimizing risk and many organizations adopt that approach for their business-critical systems.  

In addition to migration to Oracle Exadata, customers use GoldenGate, and Oracle Data Integrator, with Exadata in a variety ways leveraging the natural fit between these technologies:

  • Active-active database synchronization across the globe for data distribution, continuous availability, and zero downtime maintenance purposes.
  • Real-time or near real-time data loading to data warehouse, or consolidated database, on Oracle Exadata from heterogeneous sources. Oracle Data Integrator plays the major role in this use case as it integrates with GoldenGate and loads data warehouse in near real-time after performing transformations within the Exadata machine. This use case will be another blog topic soon as it is a strong best practice for performing ETL/ E-LT for Exadata.
  • Moving change data from an OLTP application running on Exadata in real time, for downstream consumption by other systems including supporting service integration.

As additional resources on best practices for migrating to Exadata I'd like to point you to couple of great white papers: Zero-Downtime Migration to Oracle Exadata Using Oracle GoldenGate and Oracle GoldenGate on Exadata Database Machine.

And the Winners of Fusion Middleware Innovation Awards in Data Integration are…

At OpenWorld, we announced the winners of Fusion Middleware Innovation Awards 2012. Raymond James and Morrison Supermarkets were selected for the data integration category for their innovative use of Oracle’s data integration products and the great results they have achieved.

In this blog I would like to briefly introduce you to these award winning projects.

Raymond James is a diversified financial services company, which provides financial planning, wealth management, investment banking, and asset management. They are using Oracle GoldenGate and Oracle Data Integrator to feed their operational data store (ODS), which supports application services across the enterprise. A major requirement for their project was low data latency, as key decisions are made based on the data in the ODS. They were able to fulfill this requirement due to the Oracle Data Integrator’s integrated solution with Oracle GoldenGate.

Oracle GoldenGate captures changed data from different systems including Oracle Database, HP NonStop and Microsoft SQL Server into a single data store on SQL Server 2008. Oracle Data Integrator provides data transformations for the ODS. Leveraging ODI’s integration with GoldenGate, Raymond James now sees a 9 second median latency (from source commit to ODS target commit).

The ODS solution delivers high quality, accurate data for consuming applications such as Raymond James’ next generation client and portfolio management systems as well as real-time operational reporting. It enables timely information for making better decisions.

There are more benefits Raymond James achieved with this implementation of Oracle’s data integration solution. The software developers and architects of this solution, Tim Garrod and Ryan Fonnett, have told us during their presentation at OpenWorld that they also reduced application complexity significantly while improving developer productivity through trusted operational services. They were able to utilize CDC to generate alerts for business users, and for applications (for example for cache hydration mechanisms).

One cool innovation example among many in this project is that using ODI's flexible architecture, Tim and Ryan could build 24/7 self-healing processes. And these processes have hardly failed. Integration process fixes the errors itself. Pretty amazing; and a great solution for environments that need such reliability and availability. (You can see Tim and Ryan’s photo with the Innovation Awards trophy above.)

The other winner of this year in the data integration category, Morrison Supermarkets, is the UK’s 4th largest grocery retailer. The company has been migrating all their legacy applications on to a new-world application set based on Oracle and consolidating all BI on to a single Oracle platform. The company recently implemented Oracle Exadata as the data warehouse engine and uses Oracle Business Intelligence EE.

Their goal with deploying GoldenGate and ODI was to provide BI data to the enterprise in a way that it also supports operational decision making requirements from a wide range of Oracle based ERP applications such as E-Business Suite, PeopleSoft, Oracle Retail Suite. They use GoldenGate’s log-based change data capture capabilities and Oracle Data Integrator to populate the Oracle Retail Data Model. The electronic point of sale (EPOS) integration solution they built processes over 80 million transactions/day at busy periods in near real time (15 mins). It provides valuable insight to Retail and Commercial teams for both intra-day and historical trend analysis.

As I mentioned in yesterday’s blog, the right data integration platform can transform the business. Here is another example: The point-of-sale integration enabled the grocery chain to optimize its stock management, leading to another award: Morrisons won the Grocer 33 award in 2012 - beating all other major UK supermarkets in product availability. Congratulations, Morrisons,on another award!

Celebrating the innovation and the success of our customers with Oracle’s data integration products was definitely a highlight of Oracle OpenWorld for me. I look forward to hearing more from Raymond James, Morrisons, and the other customers that presented their data integration projects at OpenWorld, on how they are creating more value for their organizations.

Leaders Discuss at OpenWorld: Achieving Zero Downtime Upgrades and Migrations

OpenWorld brings us another exciting session about a hot topic: system upgrades and migrations. This time it is a panel discussion between industry leaders that undertook pretty large projects with strict requirements for minimizing downtime. Fedex, SiriusXM Radio, and Dell will talk about the best practices they followed in their highly-critical migration projects and how they removed the risk of interrupting business operations leveraging Oracle GoldenGate.

On this blog site and in many of our webcasts we have talked about Oracle GoldenGate’s unique solution for upgrades and migrations. GoldenGate’s real-time, bi-directional, and heterogeneous data replication capabilities enable to switch over to the new system without downtime. It also offers a failback option by keeping the old system in synch after the switchover,  in case the new system experiences a problem. In this session, we will hear from these select customers how they configured GoldenGate for their unique project requirements.

Fedex will talk about how they are moving their data centers, and SiriusXM Radio will talk about how they consolidated data models for subscription management system after the merger. Dell’s discussion will include how they migrated their Active-Active replication environment that used Oracle Streams in the past to Oracle GoldenGate.

If you will be at Open World, and have any plans for systems upgrades or migrations, don’t miss the opportunity to hear the real-life implementation stories, lessons learned and, best practice tips.

What’s New in the Data Integration Market?

Data integration is essential to many strategic IT initiatives including master data management (MDM), modernization, and service-oriented architecture (SOA). That’s why it is not surprising that the data integration market continues to grow in its size, importance and impact on enterprise information systems. The technology has evolved from simple extract, transform, and load (ETL) procedures to include real time data movement, bi-directional replication/synchronization along with data quality and data profiling and data services.

 The user base for data integration tools has also evolved from low-level technology for developers and DBAs to high-level environments for operations staff, data stewards, business analysts and enterprise architects. In short, what was once merely the background “plumbing” underlying our information systems now influences just about every aspect of IT, and touches just about every type of stakeholder.

 In a new white paper we have examined the state of the data integration market including the trends in business intelligence, data warehousing, data quality, consolidation, cloud computing and IT modernization initiatives that are driving data-intensive projects. You can access this brand new white paper along with other data integration focused white papers and resources here.
