RTR for Linux x86_64 - OpenVMS Systems

HP Reliable Transaction Router Version 5.2 for
HP Linux x86_64 bit servers
HP Reliable Transaction Router (RTR) is fault tolerant
transactional messaging middleware used to implement
large, distributed applications using client/server technology. This version of Reliable Transaction Router enables enterprises to deploy distributed applications on
Linux x86_64 bit servers.
Reliable Transaction Router enables distributed applications to run in heterogeneous environments, allowing client and server applications to interoperate on the
supported Linux, Windows, HP-UX, and OpenVMS platforms.
Reliable Transaction Router provides APIs for development of distributed applications using languages such
as C and C++,exit with all-or-nothing transaction semantics as well as an optional message broadcasting capability. C API calls are also available from a command
line interface. The C++ API provides an object-oriented
interface for developing user and system management
applications. Applications can also use the X/Open XA
Reliable Transaction Router provides a reliable, transparent, 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 software 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 operate 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 software model. Client applications call the RTR client software 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 applications 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 routing 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 communications protocol. This facilitates single-node development,
and transparent scalability of applications in complex
network configurations.
Reliable Transaction Router software fault tolerant features such as router failover and shadow-server processing 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 authentication 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 procedures using real-time flow control techniques. Use of
these features generally requires no special user application programming logic.

HP Linux x86_64 bit servers
The RTR system management interface is available as
a command line interface and a web-based interface.
The web-based interface provides a point and click style
of managing RTR from a browser. The browser interface provides monitoring and management of the RTR
configuration with the RTR Manager.
• Provides publish/subscribe broadcast (nontransactional) messaging for delivery to multiple subscription
domains within a virtual network.
Both interfaces allow the creation, deletion, and modification of application networks (facilities) within a network, and permit control of distributed RTR processes
from a single system in the distributed environment. The
RTR system management interfaces are used to bind
the physical hardware (CPU and communications) to a
virtual network namespace and are transparent to the
applications software. A monitoring utility can be invoked to report application performance information on
a local or remote node.
• Acts as a layer between client and server applications, thus decoupling the end-to-end relationship
normally required by user application control. This
provides the application developer with a single system view of the programming environment.
• Allows user-defined partitioned data models (contentbased routing) for improved performance of user applications.
• Ensures atomicity of transactions (all or nothing) by
using a two-phase commit protocol for transactional
message delivery among one or more server applications.
• Offers at-most-once semantics for valid transactions.
This includes specially flagged transaction replay to
a surviving server application, or a later instantiation
of that server on the same or a different machine on
the virtual network.
Reliable Transaction Router is independent of forms and
window management systems and databases. Multiple
databases and other resource managers (for example,
flat-file systems) can be updated within the same distributed transaction.
• Supports multiple (concurrent) servers as well as
multithreaded clients and servers.
Reliable Transaction Router is intended for distributed
applications that require continuous computing services
and transaction integrity (for example, trading systems,
banking systems, electronic commerce, payment systems, transportation systems, and telecommunications
• Supports user authentication control (callout servers)
with consistent reply in shadow environments.
• Provides disaster protection against site failure by
mirroring transactions in shadow-server environments. Automatic resynchronization of shadow pairs
after recovery is provided transparently to the application.
Reliable Transaction Router can also be used for applications that require reliable messaging and fault tolerant application control over LANs or WANs. Reliable
Transaction Router provides the enabling technology for
applications requiring fully distributed client/server models.
• Maintains performance scaling over a wide range of
configurations allowing easy horizontal expansion of
both hardware systems and application software.

• Enables automatic failover/failback of server applications on multiple backend systems while remaining transparent to client applications executing on remote systems. RTR can maintain application operation in many instances of single or multiple failures in
a widely distributed software/hardware configuration.
Reliable Transaction Router for HP Linux x86_64 bit has
two license types. The Backend license provides full
client/router/server functionality. It is required for nodes
configured as routers or servers, and can also be used
for nodes configured as clients.
• Includes system management interfaces for online
control of virtual networks from any workstation or
terminal with the appropriate privileges. Monitoring of
statistics, software and hardware states, and clients
and servers is provided from local and remote nodes.
The Frontend license provides client application functionality only, in a production environment, plus a singlenode development and testing environment for RTR applications.
• Uses TCP/IP as the underlying network transport.
Reliable Transaction Router provides an interface for
controlling transaction commitment directly with an XAcompliant resource manager, such as ORACLE9.
• Enables the operator to manage partitions, providing
the ability to:
— Create or delete a partition with a user-specified

— Define a key range definition.
• Provides transparent, content-based transaction
routing for client/server applications.
— Select a preferred primary node.
