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.
