Currently we see a great demand from customers for consolidating their databases to Oracle Exadata. As they embark on these projects, they also seek a solution to avoid interrupting availability of their business-critical systems, as it can significantly impact revenue, productivity, and customer satisfaction.
Oracle GoldenGate’s real-time, heterogeneous data replication capabilities come very handy in these migration and consolidation projects. It synchronizes old environment, for example DB2, SQL Server or an earlier version of Oracle Database, with the new Oracle Exadata system in real time. While the new environment is prepared and tested, Oracle GoldenGate captures every new transaction from the production system and delivers to Oracle Exadata as soon as it is ready. Once the systems are in sync applications and users can be pointed to the Exadata system immediately without any downtime.
Exadata:
Oracle Exadata is a database appliance with support for both OLTP and OLAP workloads. It was initially designed in collaboration between Oracle Corporation and Hewlett Packard where Oracle designed the database, operating system (based on the Oracle Linux distribution), and storage software whereas HP designed the hardware for it. With Oracle’s acquisition of Sun Microsystems, Oracle announced the release of Exadata Version two with improved performance and usage of Sun Microsystems Storage Systems technologies.
