Description
PRODUCT NAME: HP Reliable Transaction Router Version 4.2 for 80.67.04
Sun Solaris
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
Sun™ Solaris™ systems.
License Types
Reliable Transaction Router for Sun Solaris 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.
Backend Features
• Provides transparent, content-based transaction
routing for client/server applications.
• Provides publish/subscribe broadcast (nontransac-
tional) messaging for delivery to multiple subscription
domains within a virtual network.
• Allows user-defined partitioned data models (content-
based routing) for improved performance of user ap-
plications.
• Acts as a layer between client and server applica-
tions, thus decoupling the end-to-end relationship
normally required by user application control. This
provides the application developer with a single sys-
tem view of the programming environment.
• Ensures atomicity of transactions (all or nothing) by
using a two-phase commit protocol for transactional
message delivery among one or more server appli-
cations.
• 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.
• Supports multiple (concurrent) servers as well as
multithreaded clients and servers.
• Supports user authentication control (callout servers)
with consistent reply in shadow environments.
• Provides disaster protection against site failure by
mirroring transactions in shadow-server environ-
ments. Automatic resynchronization of shadow pairs
after recovery is provided transparently to the appli-
cation.
• 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 appli-
cations on multiple backend systems while remain-
ing transparent to client applications executing on re-
mote systems. RTR can maintain application opera-
tion in many instances of single or multiple failures in
a widely distributed software/hardware configuration.
• 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.
• Uses HP TCP/IP as the underlying network transport.
HP DECnet is also supported.
