autotask ticketing

Multi-threaded interview shared data resolution:A. What is multithreading? threads are a single sequential control flow in a program. Running multiple threads at the same time in a single program completes different tasks, called multithreading.All of the threads are running serially in the micro, but on the macro you can feel that they are running in paralleltwo. Multi-threaded interview shared data resolution 1, assuming that each thread runs the same code that can use the same Runnable object

And this does not ache does not itch the function to the user to be able to play a very big role? This is the only people to try it in person; Second, a variety of various kinds of ticket-grabbing plug-ins, in fact, in a certain sense are limited, e

ado|server| Control 1 Concurrency consistency issues Common concurrency problems include: lost modifications, non-repetitive reading, dirty data reading, Phantom Reading (phantom reading is often classified as a type of non repeatable reading in some data). 1.1 Missing modifications Let's take a look at an example to illustrate inconsistencies in the data that comes with concurrent operations. Consider a sequence of events in the aircraft booking system: A

Use Sp_add_job to add new jobs performed by the SQLServerAgent service.2. Create job schedule using Sp_add_jobschedule.3. Use Sp_add_jobstep to add a step (action) to the jobThe following is an example of a script in the bus terminal ticketing system, and before lookin

characteristics of the hidden mechanism of the task, once an exception is generated, if we do not invoke the corresponding method or property to view the exception, we cannot determine whether there is an exception (the task does not actively throw an exception). When a task object is reclaimed by GC, the Finalize method checks for an unhandled exception, and if it is unfortunate, then the Finalize method throws the AggregateException again, and if unfortunately we do not catch the exception, O

Std::thread.TicketingA total of 100 Noah's Ark ferry tickets, there are 2 ticket points A and b at the ticket ($ 10 billion for a ticket), pawn ticket sold out on the end. We know that when the program starts the process it will create a main thread, so you can create 2 threads A and B on the main thread, then the threads A and B are sold separately, and the pawn ticket number is 0, ending threads A and B. This is accomplished with the std::thread of cocos2d-x3.0 and c++11.multi-thread

queue can be more efficient than a web server that processes static files. Static files must at least call file IO. The number of concurrent operations that can be processed by the static file web server. At the same time, the front-end controls the frequency at which the user queries the queue location with the ticket ID. High load can be 1 second or longer. In order to prevent the user from writing a script to refresh this request (although it does not make much sense, because many of the ref

ticket was issued in a bid. In the morning, the first person in the queue at the railway station could not buy the ticket. At present, tickets are issued at all ticketing sites and railway stations, which solves this problem to a certain extent. (Because the Ministry of Railways has relevant regulations, the ticket must be issued by a person ). Therefore, if you investigate and think deeply, find the crux of the problem, and solve it with a simple id
