WebApr 30, 2024 · In Distributed systems, we neither have shared memory nor a common physical clock and there for we can not solve mutual exclusion problem using shared variables. To eliminate the mutual exclusion problem in distributed system approach based on message passing is used. WebGenerally speaking there are three ways of handling deadlocks: Deadlock prevention or avoidance - Do not allow the system to get into a deadlocked state. Deadlock detection and recovery - Abort a process or preempt some resources when deadlocks are detected.
