The cache tables reside in the application tier and • Real-time performance for offload computing cycles from backend systems, enabling Oracle data • Unlimited read/write caching remarkably responsive and scalable real-time applications. Cache • Oracle Database integration Connect to Oracle manages the cache tables in the Oracle TimesTen • Flexible “cache group” definitions database, provides update propagation in both directions, enables • Automated data loading and pass through of SQL requests for non-cached data in Oracle refresh • Transactional update Database, and automatically resynchronizes data after failures. propagation Cache Connect to Oracle is fully compatible with the Replication – • Synchronous and asynchronous write-through to TimesTen to TimesTen option. Oracle • Transparent SQL pass through Real-Time Performance for Oracle Data • High availability and The majority of data in corporate databases is historical and infrequently accessed. automatic resynchronization But, buried within this data are pockets of information that should be instantly • Dynamic data caching and data aging accessible when requested. Your best customers, open orders, recent transactions • Web-based configuration and product catalog are examples. Cache Connect to Oracle enables such utility information to be automatically copied and managed in Oracle TimesTen In- Memory Databases for real-time access. Cache Connect to Oracle provides the connection and bi-directional transfer of data between an Oracle Database and an Oracle TimesTen In-Memory Database. By managing data in memory, and optimizing data structures and access algorithms accordingly, database operations execute with maximum efficiency, achieving dramatic gains in performance, even compared to a fully cached disk-based RDBMS.
