Oracle TimesTen In-Memory Database Oracle TimesTen In-Memory Database is a memory-optimized relational database that provides applications with extremely fast response time and very high throughput as required by many applications in a wide range of industries. Deployed in the application tier, TimesTen databases reside entirely in physical memory with persistence to disk storage for recoverability. Applications access the in-memory databases using standard SQL interfaces. High availability is provided through real-time transactional replication. INDUSTRY LEADING FAST AND RELIABLE SQL IN-MEMORY DAT ABASE KEY FEATURES Real-Time Performance Oracle TimesTen In-Memory Database (TimesTen) delivers real-time performance by changing the assumptions around where data resides at runtime. By managing data in Microsecond response time Multi-user concurrency In addition to using the conventional client/server connections to the database, Transactional parallel replication applications may further improve on transaction response time by embedding the Supports SQL and PL/SQL via ODBC, JDBC, ODP.NET, OCI and Pro*C/C++ TimesTen database within the application, thus eliminating inter-process communication memory, and optimizing data structures and access algorithms accordingly, database operations execute with maximum efficiency, achieving dramatic gains in responsiveness and throughput, even compared to a fully cached disk-based RDBMS. Real time performance Consistent response time Automated database failover Zero data loss Supports OLTP and analytic workloads Figure 1. Oracle TimesTen In-Memory Database

Real-time data management has two performance dimensions – response time and throughput. With TimesTen, a transaction that reads a database record can take 2.37 microseconds, and transactions that update or insert a record can take less than 8 microseconds (measured on Oracle Linux running Intel Xeon E5-2680 2.7GHz REAL-TIME DAT A MANAGEMENT FOR PERFORMANCE-CRIT ICAL APPLICAT IONS Capital markets Call Center applications Self-service portals Smart Metering Real Time Business Intelligence of transactions per second, using commodity hardware. processors).

Active Standby with Read-only Subscribers Asynchronous and synchronous replication High Availability Active Standby Availability is an essential requirement for most real-time applications. Industries that operate 24x7, such as telecommunications, and global systems that are Webaccessible, such as travel and reservations sites, cannot tolerate service downtime. Securities trading systems must remain continuously available while financial markets Parallel replication for high throughput are open. The more real-time the system, the more likely it needs to be highly available. Streaming TCP/IP...
