Thursday, August 20, 2009. Recovery or Deadlock Recovery. Abort all deadlock processes. And release resource - too drastic. Will lead to loss of work. Abort one process at a time. Releasing resources until no deadlock. How do we determine which process to abort first? Process which has done least work. Processes from a previous checkpoint. Ie before it claimed any resources. Difficult to achieve - sometimes impossible. Complex decisions due to the large number of processes present within a system. Resour...

Thursday, August 20, 2009. No Preemption –. If a process that is holding some resources requests another resource that cannot be immediately allocated to it, then all resources currently being held are released. Preempted resources are added to the list of resources for which the process is waiting. Process will be restarted only when it can regain its old resources, as well as the new ones that it is requesting. Deadlock prevention - low device utilization and reduced system throughput.
