What are some effective deadlock resolution strategies?
There are several strategies to resolve deadlocks, including resource preemption, process termination, and wait-die or wound-wait schemes.
Can you explain the wait-die and wound-wait schemes?
Sure! In the wait-die scheme, older transactions wait for younger ones to release resources, while younger ones are aborted. In wound-wait, younger transactions are aborted if they request resources held by older ones.
Which strategy is the most commonly used?
Resource preemption is often the most commonly used strategy, as it allows the system to reclaim resources from processes to resolve deadlocks.
Are there any drawbacks to these strategies?
Yes, each strategy has drawbacks. For example, resource preemption can lead to starvation, while process termination can result in loss of progress.
