Transactional databases lock active records, preventing other queries from accessing them. NOTE: Deadlocks may also occur when two or more queries are run on a database. By ensuring data is accessible when needed, programmers can protect their applications from hanging or crashing. For example, instead of having two processes rely on each other, the source code can be written so that each thread finishes before another thread needs its resources. process is free or if occupied, by which process it is occupied. ![]() Avoiding Deadlocksĭevelopers can prevent deadlocks by avoiding locking conditions in their programming logic. Process-2 requests the printer, waits deadlocked A process must request a resource before using it. Since neither process can continue until the other one completes, a deadlock is created. A deadlock is a situation in which two computer programs sharing the same resource are effectively preventing each other from accessing the resource, resulting. The result is that process 1 and process 2 are waiting for each other to finish.
