TimesTen 4.5 Released for General Availability; Real-Time Event Processing System Gains Throughput, RDBMS Adapter, and Event Notification Enhancements.

Business Editors/High-Tech Writers

MOUNTAIN VIEW, Calif.--(BUSINESS WIRE)--Sept. 30, 2002

TimesTen, Inc. today announced the general availability of version 4.5 of its infrastructure software product, the TimesTen(R) Real-Time Event Processing System. TimesTen's system enables applications to process massive transaction volumes and respond instantly to requests -- a fundamental requirement of business-critical applications in telecom and networking, financial services, travel and logistics, and real-time enterprises. The main enhancements in version 4.5 include a doubling of throughput for distributed, replicated configurations, increased sophistication and performance for event notifications, and an RDBMS adapter for extending TimesTen's real-time performance to Oracle data.

TimesTen's focus over the last year has been in support of high-volume billing and mediation systems in the telecom market, and trading infrastructures for Wall Street firms. These applications have similarly rigorous and sophisticated real-time event processing requirements -- where information must be captured, stored, used, and distributed in real-time, while preserving transactional integrity and continuous availability. The enhancements in TimesTen 4.5 address a growing installed-base and deployments in these demanding real-time event processing environments. TimesTen's customer base now exceeds 160 organizations worldwide.

Highlights of TimesTen 4.5

-- Throughput Increase for Replicated Configurations

With this release of TimesTen, updates to data can be

replicated to other TimesTen systems roughly twice as fast as

previously. A majority of TimesTen's customers deploy multiple

servers with TimesTen, and use change replication between them

for both load sharing and high-availability failover

protection. When network transfers are introduced into any

system, the overhead of the network will diminish the

effective throughput. With TimesTen, network overhead is

particularly noticeable given the very fast rate at which the

product can process transactions. With version 4.5, the value

of a distributed configuration, as measured in transactions

per dollar of hardware and software invested, could increase

by as much as 100%.

-- Sophisticated Event Notification

Version 4.5 adds a materialized view feature, to which

TimesTen's existing event notification API can be attached,

giving users the ability to more easily define and monitor

sophisticated events occurring within the system. A

materialized view pulls together in one place data and

calculated results related to specific events upon which

actions might be taken. An application using TimesTen's event

notification features only needs to monitor update records

that are of interest from a single materialized view. Without

a materialized view, the application would have to monitor all

of the update records from all of the underlying tables,

including records reflecting updates to rows and columns of no

interest to the application. For example, notification may be

desirable when:

-- The value of an "A list" customer's total trades for the day exceeds $1,000,000

-- The average stock price within a sector trades down by more than 20% in the day

-- A prepaid balance is depleted

-- A network element is taken offline

-- A flight changes departure gates

-- RDBMS Adapter for Oracle

This facility replicates portions of an Oracle database into

TimesTen for real-time processing, and automatically maintains

consistent updates between Oracle and TimesTen, in both

directions. Through this RDBMS adapter, TimesTen can be used

as a cache to pull forward information such as subscriber

profiles, against which real-time requests can be validated.

This also enables real-time information to be captured in

TimesTen and propagated to Oracle, as it's no longer needed

for real-time processing. Although TimesTen is usually

configured as a stand-alone data manager, a significant

percentage of TimesTen's customers also integrate their

real-time processing in TimesTen with back-office RDBMS

functions.

-- Additional New Features

Version 4.5 adds additional features requested by customers,

such as a sequence number generator to guarantee unique key

values, performance increases on multi-row read, update,

insert, and delete operations, and dynamic replication

reconfiguration.

"In tough economic times, companies seek ways to lower their cost structures and distinguish their products and services from their competitors," said James R. Groff, CEO of TimesTen, Inc. "TimesTen 4.5 contributes to both causes. The enhancements in this version were designed in close collaboration with world-class customers, which is one of the reasons our real-time event processing system continues to gain popularity."

TimesTen 4.5 supports Sun Solaris, Linux, Windows, HP-UX, IBM AIX, and LynxOS. For the product data sheet or to submit an evaluation request, please visit:
