By monitoring the memory configuration of SQL Server, you can determine whether the memory usage is fixed or remains in a stable State. Use Performance Monitor of Windows 2000 to

SQL Server passes the lock, just like a traffic light at a crossroads, to tell all concurrent connections that at the same time those resources can be read and those resources can be mod

the operations made by the concurrent connection reach a certain expectation, the resource is manually locked (the lock can be regarded as a flag in essence ). When a connection operates on a specific resource, operations on the same resource at the same time by the other connection will be blocked (of course, this is related to the compatibility between locks, A more in-depth discussion of the lock is beyond the scope of this article.
