Recently, some friends talked about system performance analysis. The best way to analyze why a Java-based system is slow is to use profiler. The principle of profiler is to use some drivers and JVM bindings to read the JVM runtime and get the time from loading the class to the execution to the end of the entire process, so as to know the methods of those functions make your system slow. Good open-source

19.2.1 understand SQL Server Profiler SQL Server Profiler is a graphical real-time monitoring tool that helps the system administrator monitor database and server behaviors, such as the number of deadlocks, fatal errors, and track Transact-SQL statements and stored procedures. You can store the monitoring data into tables or files and re-display these events at a later time for further analysis. We usually

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

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
