Agenda

• Oracle Approach

• Embedded Databases• TimesTen In-Memory Database

• Snapshots• Q&A

Real-Time Infrastructure ChallengesVery high data throughput rates – Accelerating…• Joint Operations across Services and Allies• Global Information Grid• RFID & other Sensors Everywhere• Wireless Communications

Flexible Infrastructure Requirement• Standards• Strong Desire for COTS• Service Oriented Architecture

Oracle’s Approach…

• Secure• High Performance• Standards Based and Interoperable• Based completely on “COTS”

products• Ease of integration (embeddable)

Which Embeddable Database?• Speed! Microsecond latency and 100,000+ TPS• Cache synchronization with Oracle DB in real-time• SQL, ODBC, JDBC • Embedded or client-server operation• In-Memory database for ultimate performance

• Low latency and high throughput• Embedded only operation • Non-relational queries, very small footprint (< 200 kb)• XML/XQuery capable

• Synchronization to Oracle Database (periodic)• Very small embedded footprint (<200kb) for handheld devices• SQL & Stored Procedures

• Performance, Reliability, Security and Portability• Handles any possible SQL or data type such as Spati al• Footprint is not a constraint10g

In-Memory Database Technology

• Entire database is in-memory

• Memory optimized indexes and algorithms: 10x CPU efficiency

• Choice of embedded or client/server options

• Standard APIs (ODBC, JDBC, SQL)

• Flexible durability options for data persistence to disk

• Embedded class ease-of-use

• Excellent data replication for high availability

In-Memory Database� Relational, standard API’s

� Very fast response

� Very high transaction rates

� Enterprise scalability & reliability

TimesTen-to-TimesTen Replication

• Replicate entire databases or individual tables

• Dynamic configuration with SQL

• Automatic recovery and catch-up of down systems

• Asynchronous or synchronous (dynamic configuration with SQL)

• Does not include a cluster manager (no automatic failover)

Master - Subscriber

Master - Master

N-Way

ACID Properties• Atomicity: full support for transactions

(COMMIT/ROLLBACK)• Consistency: database is always in a consistent

state, and recovers from disk in a consistent state• Isolation and locking:

• Row-level locking• Thread safe• READ COMMITTED isolation• Writes do not block reads• Reads do not block writes • SERIALIZABLE isolation also available• Lock timeouts and deadlocks- very rare

• Durability:• Transactions logged to disk and recovered

Cache Connect to OracleApplication-Tier Data Access

Key Takeaways…

• Pre-load or load-on-demand the most active data from Oracle

• Synchronizes updates in both directions

• Transparent SQL pass-through for non-cached data requests

• IMDB keeps working even if the connection to Oracle is down

Snapshots & Case Studies

TimesTen becoming widespread in DoD/Intelligence community

• TimesTen being used or evaluated by many Defense/Intelligence customers.

• How is it used?• Command and Control• Large memory decision support systems• Data Fusion• Data Distribution and Messaging• SOA• Application Tier Caching• Embedded DB in Real-Time Applications

•RTI(Real-Time Innovations) is the leading real-time messaging vendor

•Customers include U.S. Navy, U.S. Air Force, U.S. Army, Northrop Grumman, Raytheon,Lockheed Martin, BAE Systems, etc.

•DDM scales to hundreds of nodes

•Publishes data from one to many

•Used on ships and battlefieldoperations control systems

•DDM Embeds Oracle’s IMDBso Real-time database nodes can be distributed everywhere

Example: Joint Forces

• Proof of Concept with live data• Integrate Army, Air Force and Navy Systems• Pull data from 3 different interfaces

• SOAP/XML• Direct Flat File Interface• Spreadsheet

• Requirement: Application-Mid-Tier must function even when disconnected from back-end Database
