Some other fault tolerance techniques that are not mentioned in the web search results are:
Software Rejuvenation: This technique involves periodically restarting the software components or the whole system to prevent or recover from software aging, which is the degradation of software performance or reliability over time due to memory leaks, resource exhaustion, data corruption, etc. Software rejuvenation can help prolong the system lifetime and availability by restoring the system to a clean state and releasing the accumulated resources.
Exception Handling: This technique involves defining and implementing procedures to deal with exceptional or unexpected situations that may occur during the normal execution of a software system, such as input errors, output errors, communication failures, resource unavailability, etc. Exception handling can help improve the system robustness and reliability by preventing the system from crashing or producing incorrect results when an exception occurs.
Self-Healing: This technique involves enabling the software system to detect, diagnose, and repair its own faults or failures without human intervention. Self-healing can help improve the system resilience and adaptability by allowing the system to recover from faults or failures and restore its normal functionality.
These are some of the other fault tolerance techniques that can be used to enhance the dependability and quality of a software system.
