Sometimes we need to analyze our own games or other people's games, for example, we need to understand the general rendering process of an engine, this time we can use some tools, on the PC we can using the Microsoft PIX, Intel GPA, Nvidia's nsight and Perfhud to intercept a frame of data for analysis. Because of the recent move to the mobile platform, sometimes also need to analyze the game, this time we can use the tools of different graphics vendors to analyze. Here, we analyze a program usin

The following is a piece of Python that implements profiler through metaclass. Code It is very simple and has few functions. It aims to display Python Meta Programming's ability is undoubtedly very practical, and can bring the concept of aspect into play very well!

From the big aspect, the bug is nothing more than: database bug; program bug.SQL capture is useful in practical applications. For those unknown bugs, when you don't know where to go, capture SQL directly and execute SQL.Application Details 1The company does web-side projects and mobile-phone projects to integrate data.

Original: 16th--handling locks, blocks and deadlocks (3)--Detecting deadlocks using SQL Server ProfilerObjective:As a DBA, it may be common for colleagues or customers to respond to frequent deadlocks that affect the use of the system. At this point, you need to detect and deal with such problems as quickly as possible.Deadlocks are caused when two or more of the transactions are blocked from one another. In this case, two transactions will wait indefinitely for the other to release the resource

Label:Preparatory work:In order to detect deadlocks, we need to simulate the deadlock first. This example creates two transactions using two different sessions. Steps:1. Open SQL Server Profiler 2. Select "New trace" to connect to the instance. 3. Then select "Blank" Template: 4. On the Event Selection page, expand the Locks event and select the following event: 1. Deadlock graph 2, Lock:deadlock 3, Lock:deadlock Chain 5. Then open the TSQL event

In fact, after the discovery is still relatively simple, but there are a few more attention to the placeI. Using Unity for Android development, it is important to remember to back up the Android development environment, which is the SDK. As soon as the SDK is updated, it is possible to change the file structure within the SDK, so unity cannot find the file correctly, and the build will continue to error. Although there are various solutions online, but I personally think the first is trouble, th

During data query optimization, set statistics IO/time on is added before the SQL statement to run and view the IO, reads, CPU usage time, and other information of the current statement. This information is obtained repeatedly by adding, removing, or modifying indexes to check whether the statement has been optimized. In SQL Server 2005, there is an SQL Server Profiler that can track SQL events and analyze applications.ProgramThe statistical informa

The main purpose of MySQL's SQL Performance Analyzer is to show how resources are used throughout the process of SQL execution.
