PRODUCT NAME: HP Reliable Transaction Router Version 5.2 for 82.42.03

Linux on Integrity servers

DESCRIPTION

HP Reliable Transaction Router (RTR) is fault tolerant

transactional messaging middleware used to implement

large, distributed applications using client/server tech-

nology. This version of Reliable Transaction Router en-

ables enterprises to deploy distributed applications on

Linux Integrity servers.

Reliable Transaction Router enables distributed appli-

cations to run in heterogeneous environments, allow-

ing client and server applications to interoperate on the

supported Linux, Windows, HP-UX, and OpenVMS plat-

forms.

Reliable Transaction Router provides APIs for develop-

ment of distributed applications using languages such

as C and C++, with all-or-nothing transaction semantics

as well as an optional message broadcasting capabil-

ity. C API calls are also available from a command line

interface. The C++ API provides an object-oriented in-

terface for developing user and system management

applications. Applications can also use the X/Open XA

interface.

Reliable Transaction Router provides a reliable, trans-

parent, dynamic message-routing system that includes

both a transactional and non-transactional message

control system. RTR transaction management supports

two-phase commit of distributed transactions.

Reliable Transaction Router implements automatic soft-

ware fault tolerance and failure recovery in multinode

environments by adapting to many kinds of hardware

(CPU), communications, application software, and site

failures. Automatic failover and recovery of service op-

erate by exploiting redundant or alternate hardware and

network links. If alternate hardware or network links

are not available, RTR automatically continues service

when the CPU or network link becomes available.

Reliable Transaction Router applications are developed

and deployed using a three-tier client/router/server soft-

ware model. Client applications call the RTR client soft-

ware tier, which passes messages to the router tier of

the software. Transaction messages are routed reliably

and transparently, based on message content, to the

appropriate processes in the server tier. Server applica-

tions typically execute transactions against a database

and return results back to clients.

A single physical node may run one, two, or three tiers

of the RTR client/router/server software model. Each

of the three software tiers may consist of one or more

nodes. The software model and its content-based rout-

ing present a virtual rather than physical network to the

application developer. This model enables application

software to be independent of physical hardware (CPU)

location, network naming conventions, and communica-

tions protocol. This facilitates single-node development,

and transparent scalability of applications in complex

network conﬁgurations.

Reliable Transaction Router software fault tolerant fea-

tures such as router failover and shadow-server pro-

cessing provide continuous computing services with

completion of in-progress transactions despite single or

multiple points of failure in the distributed client/server

environment. Callout servers implement user authenti-

cation control, and concurrent servers provide dynamic

message load balancing for high performance. High

performance transactional messaging is implemented

as a full-duplex conversation with remote server pro-

cedures using real-time ﬂow control techniques. Use of

these features generally requires no special user appli-

cation programming logic.
