application running simultaneously with Analytics processing. Historically, specialized database computing platforms were designed for a particular workload, such as Data Warehousing, and poor or unusable for other workloads, such as OLTP. Exadata allows mixed workloads to share system resources fairly with resource management features allowing prioritized allocation, such as always favoring workloads servicing interactive users over reporting and batch, even if they are accessing the same data. Long running requests, characterized by Data Warehouses, reports, batch jobs and Analytics, are reputed to run many times faster compared to a conventional, non-Exadata database server.

Release History

End-of-support

As the platform has been around for over 11 years, Oracle has published information related to the end-of-support for the Exadata platform. In Oracle's published document titled ''Oracle Hardware and Systems Support Policies'', they mention "After five years from last ship date, replacement parts may not be available and/or the response times for sending replacement parts may be delayed." To look up the "last ship date" of a particular Oracle Exadata Appliance, Oracle published a document titled ''Oracle Exadata - A guide for decision makers''.
