SQL2008 no exclusive access to the database is resolved when restoringWhen you restore or delete a SQL Server 2008 database, you often see the following: "Because the database is in use, you cannot gain exclusive access to the database," The final Solution is the key SQL statement: ALTER DATABASE [datebase] SET OFFLINE with ROLLBACK IMMEDIATE run out and then ALTER database [Datebase] set onlineWhen restori

deadlocks. (iii) Improper progression of process causes deadlock In the above diagram, if the order of 1 is advanced, two processes can be successfully completed. If the sequence of 2 is advanced, two processes can be successfully completed, and if the sequence of 3 is advanced, two processes can be successfully completed; If you advance in the order of Curve 4, two processes will enter unsafe zone D, at which point P1 maintains resource R1, P2 keeps the resource R2, the system is in an unsafe

Background: Develop a set of hardware-dependent software that allows only one software process to run in a single time to avoid hardware resource invocation conflicts.Method: Use a mutex to determine if the software is started, and if so, to close the software that is about to start.Code:1 Static class Program2 {3 /// 4 ///The main entry point for the application.5 /// 6 StaticMutex _mutex;7 8 [STAThread]9 Static voidMain ()Ten { One

Label:Cause: Because when I restore the database, there are other users who are using the database, so the above prompt appears.Workaround:1, set the database to work in single-user mode.Setup method: Right-click on the database you want to restore, select Properties-> Options-> Status-> Restrict Access-> "single" On the right-click menu command. This is the menu command for SQLSERVER2005, other versions please find it yourself.2, the use of SQL statements to kill all the processes that are usin

In PHP, P's default session processor is Session.save_handler = files (i.e. file). If the same client concurrently sends multiple requests (such as Ajax sending multiple requests at the same time), and the script executes longer, it can cause the session file to block and affect performance. Because PHP executes session_start () for each request, it obtains a file exclusive lock that will not be released until the request processing is complete. In th

mutexFunction Prototypes:HANDLE OpenMutex (Dworddwdesiredaccess,Boolbinherithandle,Lpctstrlpname//Name);Function Description:The first parameter represents access rights, and the mutex is generally passed into mutex_all_access. Detailed explanations can be viewed in the MSDN documentation.The second parameter represents the mutex handle inheritance, which is generally passed to true.The third parameter represents a name. After a thread in a process creates a mutex, the thread in the other proce

The single-threaded nature of the Javascript engine makes it an exclusive thread for a long time to process a larger loop traversal, causing other events (such as user actions) to not respond in a timely manner, causing cotton even to suspend animation in serious cases. To solve the above problem, a feasible mechanism is to split a large loop into several small pieces of circular fragment execution, so that the JavaScript engine has the opportunity to
