Pessimistic lock (Pessimistic Lock), as the name implies, is very pessimistic, every time to take the data when they think others will change, so every time when the data are locked, so that other people want to take this data will block until it gets the lock. Traditional relational database in the use of a lot of this locking mechanism, such as row locks, table

Hibernate lock mechanism. Let's make a summary today. Hibernate locks include pessimistic locks and optimistic locks. 1. pessimistic lock It refers to a conservative attitude towards data being modified by the outside world. Assume that another customer may be able to access the same data at any time. To maintain the consistency of data operations, the data is locked at the database level, it depends on the

Oracle lock 4: system lock, oracle lock 4 System Oracle databases use multiple system locks to protect internal databases and memory structures. These mechanisms are transparent to users.Latches) Latches are simple and low-level serialization mechanisms that coordinate multiple users to use shared data structures, objects, and files. latches protect shared memory

By using the dependency injection framework and reverse control, you can generate and assemble custom class instances and configurations that contain dependent objects. The following section describes how to use unity. The types of objects unity can create-unity can create objects You can use the unity container

There are two types of file locks: shared and exclusive, that is, read lock (LOCK_SH) and write lock (LOCK_EX) File locks are typically used in this way: $fp = fopen ("filename", "a"); Flock ($FP, lock_sh) or Die ("LOCK error") $str = Fread ($fp, 1024x768); Flock ($FP, lock_un); Fclose ($FP); Note that after fwrite, the file is updated immediately, inste

A pessimistic lock refers to a conservative attitude towards data being modified by the outside world. Assume that another customer may be able to access the same data at any time. To maintain the consistency of data operations, the data is locked at the database level, it depends on the locking mechanism provided by the database. The database locks implemented based on jdbc are as follows: sele A pessimistic lock
