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

How to use SQL Profiler Performance Analyzer mysql's SQL Performance Analyzer is mainly used to display the usage of various resources during SQL Execution.Analyzer can better demonstrate the performance problems of poor SQL statements. The following is an example of how to use MySQL SQL Profiler: www.2cto.com. First, enable MySQL SQL Profiler mysql> SELECT @ pro

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.

What is the recommended way to loading.readobject the high cost? Loading.readobject is a resource-loading function for the unity engine that typically occurs when switching scenes and loading API calls, including textures, meshes, Material, Shader, Animationclip, and so on. If you find that the value is too high, it is recommended to vigorously optimize the associated resources for loading. For each type of resource loading, we are summarizing and sharing it in a thematic way, so we recomm

I often look at the SQL Profiler trace and feel that it is not convenient to store it as a file. After storing it in a database table, you can simply query it. However, the eventclassid column in the saved table displays numbers, unlike the ones used in profiler.ProgramShown RPC: StartingSP: StartingSP: stmtstarting And so on. After searching online, I found the following script to display eventclassid as the name. SelectTe.Name,T.*From

It tells you what event is being monitored for each row. When you save this trace to a table you can see That the eventclass no longer has a description but an ID. So how do you map this to a description? If you know where
