RTR (Reliable Transaction Router)

A fault tolerant transactional messaging middleware used to implement large, distributed applications using client/server technology.

RTR helps ensure business continuity across multivendor systems and helps maximize uptime. The back end provides transparent, content-based transaction routing for client/server applications.

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.
