RTR Continuous Computing Concepts
RTR Continuous Computing Concepts
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:
• Reliability
• Failure tolerance
• Data and transaction integrity
• Scalability
• Ease of building and maintaining applications
• Interoperability with multiple operating systems
RTR additionally provides the following capabilities, essential in
the demanding transaction processing environment:
• Flexibility
• 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.
A transaction with the ACID properties has the following
attributes:
• Atomic
• Consistent
• Isolated
• Durable
For more details on transactional ACID properties, see the
discussion later in this document, and in the RTR Application
Design Guide.
