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! The following profiler class (metaclass) can reuse the profiling of methods in different classes. Code highlighting produced by Actipro Code

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
