Chapter 25: Problem 15

Discuss the factors that do not appear in centralized systems that affect concurrency control and recovery in distributed systems.

Short Answer

Expert verified
Unique characteristics of distributed systems such as network partitioning, the absence of a global clock, asynchronous communication and global inconsistency introduce complexities for concurrency control and recovery, complexities that are not encountered in centralized systems.

Step by step solution

01

Discuss Unique Characteristics of Distributed Systems

Distributed systems are unique in several ways and have different impacts on concurrency control and recovery. Some of the main characteristics include network partitioning, the absence of a universal clock, global inconsistency, and asynchronous communication which are not present in centralized systems.
02

Explain the Impact on Concurrency Control

In a distributed system, the lack of a global clock affects concurrency control because it is difficult to order events in a global manner. Network partitioning can affect concurrency control because it may lead to inconsistent views of the system. Asynchronous communication introduces delays and uncertainties which can complicate the concurrency control mechanism, causing a risk for race conditions and deadlocks.
03

Explain the Impact on Recovery

Recovery in distributed systems is more complex due to factors like network partitioning, global inconsistency, and asynchronous communication. In the event of a failure, the system might have to deal with inconsistent states amongst different nodes. When a network is partitioned, not all parts of the system might be aware of the failure, leading to inconsistent states. Due to asynchronous communication, a node might not immediately recognize a failure, which impacts the recovery process.
