Rtr Interfaces - Compaq Reliable Transaction Router Getting Started

RTR provides interfaces for management and application
programming.
You manage RTR with a management interface from the RTR
management station. The management interfaces are:
• The command line interface or CLI
• The browser interface
The application programming interfaces (APIs) are:
• The object-oriented API for C++ programming, available with
RTR Version 4.0. Use this API for all new development and,
where appropriate, for new work on existing applications.
An application can contain both object-oriented classes and
portable API calls. This API can be used to implement
applications on all platforms supported by RTR.
• The RTR API for C programming, available with RTR V3.
This interface is also called the Portable API because it can
be used to implement applications on all platforms supported
by RTR.
• The OpenVMS API containing OpenVMS calls, available
with RTR V2. This API, supported on OpenVMS only, is
obsolete for new development. While applications using this
API should be rewritten in the new object-oriented API to
take advantage of new RTR features and capabilities, they
can be changed by adding object-oriented classes rather than
being rewritten.
You can use the command line interface to the API to write
simple RTR applications for testing and experimentation. The
CLI is described in the Reliable Transaction Router System
Manager's Manual. Its use is illustrated in this chapter.
