Introduction
This document introduces RTR and describes RTR concepts. It is
intended for the system manager or administrator and for the
application programmer who is developing an application that
works with Reliable Transaction Router (RTR).
Reliable Transaction Router
Reliable Transaction Router (RTR) is failure-tolerant
transactional messaging middleware used to implement large,
distributed applications with client/server technologies. RTR
helps ensure business continuity across multivendor systems and
helps maximize uptime.
Failure and fault
tolerance
Failure tolerance is supplied by the RTR software that enables
an application to continue even when failures such as node or
site outages occur. Failover is automatic. Fault tolerance is
supplied by systems with hardware that is built with redundant
components to ensure that processing survives failure of an
individual component. Depending on system requirements and
hardware, an RTR configuration can be both failure and fault
tolerant.
