The in-memory option is only available with the enterprise edition of Oracle's database, as is typically the case, Shetler said. Since the OpenWorld announcement, Oracle has added additional features to the in-memory option, the key one being support for its RAC (Real Application Clusters) technology, which provides scalability and fault tolerance. In contrast, Oracle's in-memory option can take advantage of the company's well-established capabilities for database scalability, high-availability and security, Shetler said. SAP is "trying really hard to finish the other parts of a database management system," he said. With the new in-memory option Oracle has an advantage over newer in-memory platforms such as Hana, said Tim Shetler, vice president of product management, in an interview prior to Tuesday's event. Oracle has already offered the TimesTen in-memory database in both stand-alone form and as a caching option for its flagship database, but that technology has tended to serve more specialized purposes. In-memory computing pushes information into RAM instead of reading it off of disk, providing significant performance boosts.
