6. Deadlock Detection and Avoidance In this method, the OS assumes that a deadlock will occur in the future. Soit runs a deadlock detection mechanism with a certain interval of time, and when it detects the deadlock, it starts a recovery approach. The main task of the OS is to detect...

4. Detection and Recovery When the system is in deadlock then one method is to inform the operates and then operator deal with deadlock manually and the second method is system will automatically recover from deadlock. There are two ways to recover from deadlock:...
• Deadlock detection and recovery 死锁监测和修复 –No restriction on resource allocation –Periodic check for deadlocks –When a deadlock is detected, recovery mechanisms are employed 5-Deadlock Prevention 分为indirect deadlock prevention 和 Direct deadlock prevention 两种 ...
In deadlock detection, the operating system considers that a deadlock situation will occur and then it will identify it. No methods for prevention or avoidance of deadlocks are applied here. So, the OS analyses if there is a deadlock. If detected, recovery methods are applied. ...

Perhaps the crudest form of deadlock detection and recovery is the watchdog timer. In event of a deadlock, the timer will elapse (deadlock detection),and reboot the system (recovery). As a last ditch safety net for very infrequent or as yet undiscovered deadlocks this is acceptable. ...
Deadlock detection potentially allows greater concurrency than deadlock prevention approaches [Davi 92]. Therefore, there is a real need for such a novel deadlock detection mechanism that high degree of concurrency can be achieved without loss of global serializability and local site autonomy in MDB...
