Migrating Oracle databases presents many unique challenges for IT administrators; such as the complexity, data integrity requirements, and 24x7 availability requirements of critical database applications. To address these challenges, Dell offers a near zero downtime migration strategy in this whitepaper, which can help customers move Oracle databases into a new infrastructure with near zero downtime impact. This methodology has been proven to be reliable and repeatable with the adoption by Dell IT for a large scale Oracle database migration project. This methodology brings out the best of Dell Compellent storage features like thin provisioning and a well tested reference architecture using the latest generation Dell PowerEdge servers.
The migration methodology provided in the whitepaper is developed based on the reference configuration shown below.
The Oracle Real Application Cluster (RAC) database is migrated from the source system to the target system. The target Oracle database system consists of not only the latest hardware including the Dell PowerEdge 12th Generation servers, Dell Compellent storage systems, and SAN switches, but also newer operating system releases on the database servers.
Complete details on the migration methodology can be found in the Oracle Database Migration to Dell PowerEdge 12th Generation Servers and Dell Compellent Storage Systems whitepaper.
