One of the most common performance bottlenecks in enterprise applications is resource reservation. Whether it is booking airline seats, reserving hotel rooms, allocating inventory etc, many applications rely on database row locking to prevent double booking. While this approach works, it becomes a serious scalability challenge during peak demand. The result is, Increased lock waits Application timeouts Poor user experience Reduced transaction throughput The question is: Can we prevent double booking without relying heavily on database locks? The answer is yes. Modern Oracle based applications can implement lock free reservation patterns that significantly reduce contention while maintaining data integrity. The Traditional Approach Most applications perform a reservation using below method. SELECT available_qty FROM inventory WHERE item_id = 100 FOR UPDATE; If sufficient quantity exists, UPDATE inventory SET ava...
