![]() Enabling High Performance Data Streaming with the Memoptimized Rowstore.Oracle Database In-Memory (Database In-Memory) is a suite of features, first introduced in Oracle Database 12 c Release 1 (12.1.0.2), that greatly improves performance for real-time analytics and mixed workloads. Improving Query Performance with Oracle Database In-Memory.Database Smart Flash Cache can greatly improve the performance of Oracle databases by reducing the amount of disk I/O at a much lower cost than adding an equivalent amount of RAM. The Database Smart Flash Cache feature is a transparent extension of the database buffer cache using solid state device (SSD) technology. If you prefer to exercise more direct control over the sizes of individual memory components, you can disable automatic memory management and configure the database for manual memory management.Īn Oracle Database instance can cache the full database in the buffer cache. You can allow the Oracle Database instance to automatically manage and tune memory for you. Understand basic memory structures associated with Oracle Database.
