Avoid Database Deadlocks with Planning

esolving deadlocks is one of the more elusive solutions in database application development. Deadlocks are the dark side of concurrency, that is, they occur when some combination of locking, coding, or transaction management goes wrong. Deadlocking represents a failure of processes to work and play well together.

In this 10-Minute Solution, I discuss the controls and settings that go into transaction management and describe how to debug deadlocks by integrating resources in a manner that balances concurrency and integrity.



How do I apply locking, coding, and transaction management in a way that strikes the correct balance between concurrency and integrity and avoids deadlocks?



Integrate resources using the proper transaction isolation levels and locks, and plan ahead with your own serialization convention to avoid deadlocks.
