What are some effective deadlock resolution techniques?
There are several techniques for deadlock resolution, including resource allocation graphs, wait-die and wound-wait schemes, and preemption.
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 the wound-wait scheme, younger transactions are forced to wait if they request resources held by older transactions.
How do these techniques impact system performance?
These techniques can improve system performance by reducing the chances of deadlocks, but they may introduce overhead due to transaction management.
Are there any other methods to prevent deadlocks?
Yes, other methods include resource ordering, where resources are requested in a predefined order, and using timeouts to abort transactions that wait too long.
