  • Oracle In-Memory Database Cache enables you to improve application transaction response times and throughput by caching performance-critical subsets of an Oracle Database in the application tier. Automatic data synchronization between the cache and the Oracle Database ensures data consistency. By bringing data closer to the application and processing queries in an in-memory database, your applications are able to access, capture, or update information many times faster.

  • Using Online Redo Log Files Online redo log files provide the means to redo transactions in the event of a database failure. Every transaction is written synchronously to the Redo Log Buffer, then gets flushed to the online redo log files in order to provide a recovery mechanism in case of media failure. (With exceptions such as direct load inserts in objects with the NOLOGGING clause enabled.) This includes transactions that have not yet been committed, undo segment information, and schema and object management statements.
