What
is HP Reliable Transaction Router?
HP
Reliable Transaction Router (RTR) is fault-tolerant middleware
(software) that ensures transaction integrity. RTR is designed for widely
distributed client/server applications that require 24 x 7 continuous
availability, disaster tolerance, and scalable performance. RTR
is used for business applications that must execute real-time transactions reliably and without any interruption
of service across widely distributed multi-vendor systems. Typical
applications include stock and option exchanges, Internet
banking and brokerages, electronic payment systems, trading and
risk-management systems, reservation systems, and telecommunications
systems.
What
is unique about RTR?
RTR
provides customers and partners with a unique, fault-tolerant software infrastructure that offers wide-area disaster tolerance,
continuous application availability, and transaction integrity
on multiple vendor platforms. RTR provides protection against
several types of failures in the distributed environment, including
network, application, database, system, and site failures. When
network, system, or site resources become unavailable, RTR
performs failover and recovery automatically and transparently to the application,
providing real-time, continuous service.
How
does RTR compare to other reliable messaging and high availability, transaction processing (TP) products?
RTR
provides wide-area site shadowing; ACID transaction integrity;
real-time, continuous processing of transactional messages even during failures; and transparent failover, recovery, and resynchronization
in a multi-vendor environment. These features protect organizations
against downtime, lost data, and slow response time, which can
affect profits and customer satisfaction.
Why would I use RTR?
To ensure that your transactions get to the database. If you initiate a transaction at a client, such as a bank ATM, RTR takes care of ensuring that it goes from the client application to the
server application and then to the database without being lost, even if one of the computers in the path, or a network link, goes away.
What is the distance limitation for RTR?
RTR extends disaster tolerance, delivering continuous operation across even global, multi-vendor networks. Redundant systems can be located thousands of miles away.
What
platforms can run RTR?
