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.
