Strict Two-Phase Locking:

Similar to plain Two-Phase Locking, the locks are acquired and released in two phases in Strict Two-Phase locking protocol.

  • After acquiring the locks in the first phase, the execution of the transaction takes place normally.
  • However, unlike Two-Phase Locking, Strict Two-Phase locking protocol does not release the lock after the execution.
  • Strict Two-Phase locking keep holds of the lock until the commit point and at the same time, it releases all the locks.

Explanation of Solution

Disadvantages of Strict Two-Phase Locking:

The only disadvantage with Strict Two-Phase Locking protocol is that it reduces con...

After playing our giving implementation, your task is to implement Dinning Philosophers with semaphore in C, by including and Your implementation will require creating five philosophers, each identified by a number 0.4. Each philosopher will run as a separate thread. Create threads using Pthreads as discussed in the Lecture slides on Chapter 4 and Practice Lab on Threads. Your solution needs to accomplish the following: Implement in C (15 points) 1. dp1.c - You are to provide your solution to this assignment as a single C program named 'dp1.c using semaphore. Explain in you code (as comments) that the dead lock will happen or not. If there is a possible deadlock, you can simply solve the deadlock by pick the fork in order like the first solution in our slides. Solve Deadlock by Footman (15 points) 1. Here is a new solution to overcome the deadlock. The Dining Philosophers decide to hire a footman whose task to allow only four philosophers to sit on the table. When entering and…
