July 15, 2008 - GoldenGate Software Inc., a leading provider of high availability and real-time data integration solutions, today announced that Bloor Research has released a report entitled “Zero-downtime Migration” which highlights the benefits of a solution from GoldenGate and the best practice approaches to addressing this key business issue. In the report, Bloor puts forward the case for a zero-downtime migration methodology that enables migrations for enterprise applications, hardware platforms and operating systems whilst maintaining continuous availability.

“In an increasingly 24 x 7 world where both customers and internal users want access to relevant applications and information at any time of the day or night on any day of the year, companies need to implement policies and technology that will ensure continuous availability rather than the merely high availability that has previously been the norm,” explained Philip Howard, Principal Analyst at Bloor Research. “High availability ensures that applications will continue to run whenever there is a failure or outage of some sort. This has historically allowed for systems to be taken down for maintenance with the assumption that planned outages in high availability systems are okay. However, for mission critical applications this is not acceptable; systems must continue to run though both planned and unplanned outages. This is what continuous availability provides.”

The GoldenGate solution highlighted in the report enables three different approaches to zero-downtime migration: unidirectional migration, the active-passive approach and active-active migration. Bloor goes on to examine each of these three methodologies, citing case studies from end user organizations, including Swedbank, Fujitsu, DIRECTV and

Zero downtime migration contrasts with the traditional “big bang” approach to migration that has been most widely used on an historic basis, whereby there is a “cut over” to the new system, typically over a weekend. With the ability to fallback from the newly migrated system to the original allows users the additional security that they will continue business as usual until any bugs or issues are corrected. Additionally, with an active-active configuration, you can run on both the old and new system for as long as you require to test and correct any issues whether they be at the application, database or platform level. It is this best practice that takes the fear out of major migration projects and allows business to continue as usual.

Howard concluded: “Zero downtime migration is, if you like, the equivalent of disaster recovery (with no loss of data and migration of user connections) within operational environments designed to ensure that key business applications are continuously available and able to cope with outages of any kind, whether planned or unplanned.”
