Tuning strategies and considerations for table locking in Oracle
Article Introduction:Table locking in Oracle is to lock the table during data operations to ensure the consistency and integrity of the data. In databases, table locking is an important control mechanism, but it can cause performance problems if used improperly. Therefore, when performing table locking, you need to pay attention to some tuning strategies and precautions to improve database performance and reduce the impact of locking. 1. Types of table locks In Oracle database, table locks can be divided into shared locks (SharedLock) and exclusive locks (Exclusive

C++ Development Notes: Avoid Misunderstandings in C++ Performance Optimization
Article Introduction:C++ Development Notes: Avoid Misunderstandings in C++ Performance Optimization In C++ development, performance optimization is a very important factor. Optimizing the performance of the code can improve the execution efficiency and response speed of the program, which is especially important for large projects and applications requiring high performance. However, when optimizing C++ performance, we also need to pay attention to some misunderstandings to avoid introducing more problems. Misunderstanding 1: Premature optimization Premature optimization is a common mistake, that is, focusing too much on performance in the early stages of writing code while ignoring the readability and maintainability of the code.
