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.
You use the architecture of RTR to ensure high availability and transaction completion. RTR supports applications that run on different hardware and different operating systems. RTR applications can be designed to work with several database products including Oracle, Microsoft Access, Microsoft SQL Server, Sybase, and Informix. For specifics on operating systems, operating system versions, and supported hardware, refer to the VSI Reliable Transaction Router Software Product Description for each supported operating system.
RTR can be deployed in a local or wide area network and can use either TCP/IP or DECnet for its underlying network transport.
RTR provides a continuous computing environment that is particularly valuable in financial transactions, for example in banking, stock trading, or passenger reservations systems. RTR satisfies many requirements of a continuous computing environment:
- Failure tolerance
- Data and transaction integrity
- Ease of building and maintaining applications
- Interoperability with multiple operating systems
RTR additionally provides the following capabilities, essential in the demanding transaction processing environment:
- Parallel execution at the transaction level
- Potential for step-by-step growth
- Comprehensive monitoring tools
- Management station for single console system management
- WAN deployability
RTR also ensures that transactions have the ACID properties that have been established as crucial in a transaction processing environment. A transaction with the ACID properties is:
