7.36- Methods For Handling Deadlocks In DBMS | DeadLock Prevention In DBMS | DBMS Free Course Online Methods for Handling Deadlocks There are Two methods for handling deadlocks. These are: Deadlock Prevention It is better to prevent the system from deadlock condition then to detect it and then recover it. Different approaches for preventing deadlocks are: 1. Advance Locking: It is the simplest technique in which each transaction locks all the required data items at the beginning of its execution in an atomic manner. It means all items are locked in one step or none is locked. Disadvantages: The disadvantages of advance locking are: 1. It is very hard to predict all data items required by the transaction at starting. 2. Underutilization is high. 3. Reduces concurrency. 2. Ordering Data Items : In this approach, all the data items are assigned in order say 1, 2, 3, ... etc. Any transaction Ti can acquire locks in a particular order, such as in ascending order or descending order. Disadvantages : It reduces concurrency but less than advanced locking. 3. Ordering Data Items with Two-phase Locking : In this approach, two-phase locking with ordering data items is used to increase concurrency. Notes Link: http://www.tutorialsspace.com/Downloa...
