Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.

which states that a resource can be released 4. One necessary condition for deadlock is only voluntarily by the process holding the resource. A) hold and wait B) mutual exclusion C) circular wait D) no preemption 5. One necessary condition for deadlock is processes whereby Po is waiting for a resource held by P1, Pı is waiting for a resource held by P2, and Pa is waiting for a resource held by Po. A) hold and wait B) mutual exclusion C) circular wait D) no preemption which states that there is a chain of waiting 6. Explain what has to happen for a set of processes to achieve a deadlocked state.
1. Two processes, A and B, each need three resources, 1, 2, and 3. Suppose 4 requests them in the order 1, 2, 3. If B also requests them in the same order, deadlock is not possible. However, if B requests them in the order 3, 2, 1, then deadlock is possible. With three resources, there are 3! or six possible orders in which B can request them. For each possible order in which B can request these resources, state whether or not a deadlock is possible for that order. (Assume that once a process acquires a resource, it does not release that resource until the end of that process.) a) 1, 2, 3 b) 1,3,2 c) 2, 1, 3 d) 2, 3, 1 e) 3, 1, 2 f) 3, 2, 1

An operating system uses the Banker's algorithm for deadlock avoidance when managing the allocation of three resource types X, Ý, and Z to three processes PO, P1, and P2. The table given below presents the current system state. There are 3 instances of type X, 2 instances of type Y and 2 instances of type Z still available. The system is currently in a safe state. Answer the following questions! Allocation Max X Y z X Y PO 0 1 8 4 3 (a) If PO requests 2 instances of Z during the P1 3 2 current state, can it be granted? Explain! (b) If P1 requests 2 instances of X during the P2 2 1 1 3 3 3 current state, can it be granted? Explain! CO
Cooperating Processes: Select all of the following statements that are true. Ordinary (unnamed) pipes provide a solution for bidirectional communication between related processes. Mechanisms for inter-process communication enable different processes to exchange information and synchronize their actions. The bounded buffer solution to the producer-consumer problem, which was the first one discussed in class and does not use semaphores or monitors, allows at most BUFFERSIZE items in the buffer at the same time.
Bounded waiting requires that \A bound must exist on the number of times that other processes are allowed to enter their critical sections a) true b) false

A process should be allowed to access only those resources for which it has authorization. Furthermore, at any time, a process should be able to access only those resources that it currently requires to complete its task. This is commonly referred to as the need-to-know principle, or domain of protection. Discuss this “domain” and its structure, including the following: Whether the relationship between a process and a domain is static or dynamic Domain switching How domain switching happens in the following cases: Each user is a domain Each process is a domain Each procedure is a domain
