Original: Using SQL Profiler to handle expensive queriesWhen the performance of SQL Server becomes worse, the following two things are most likely to occur: First, some queries produce a lot of pressure on system resources. These queries affect the performance of the entire system because the server is not able to serve other SQL queries quickly enough. Additionally, expensive queries block other queries that request the same database res

I. Description Oracle provides a profiler toolkit that allows you to view the performance of each module during PL/SQL Execution. You can download this script from MOS: Implementing andusing the PL/SQL profiler [ID 243755.1] You can also download it from my csdn: Http://download.csdn.net/detail/tianlesoftware/4051100 When there is asignificant gap between user elapsed time and SQL processing elapsed time,

When the performance of SQL Server becomes worse, the following two things are most likely to occur: First, some queries produce a lot of pressure on system resources. These queries affect the performance of the entire system because the server is not able to serve other SQL queries quickly enough. Additionally, expensive queries block other queries that request the same database resources, further reducing the performance of these queries. Optimizing expensive queries not only impr

SQL Profiler Data columns SQL Profiler allows you to select a data column when you create a template. These data columns represent the information that you want to return when you run the trace. The data that is displayed in SQL Profiler can be displayed in the order in which the event occurred, or grouped by one data column or combination of data columns. For e

. Basic use of ANTS performance Profiler ANTS Performance Profiler is Redgate's powerful performance tuning product, the official product page here. First look at the basic use of software. Use the following code for a simple test. This is a console application, the program is very simple, first 10,000 cycles, output and, then use LINQ in the list to find out the value of 1000 output. 1 static void Main ()

Use +ncprofile if is running in Single-step invocation mode with the Ncverilog command.That is, Nc-verilog integrates a profiler tool within the simulation engine that interrupts the emulator 100 times per second and logs it at the end, generating a log file (Ncprof.out) at the concl

Using PL/SQL profiler to locate PL/SQL bottleneck code for SQL optimization, you can use SQL tuning advisor to achieve automatic SQL optimization and adjustment. For PL/SQL code, there are both SQL code and PL/SQL code. It is far from enough to use only 10046 events, because the SQL time may be very short, the entire package or process is executed for a long time, and other packages, processes, and functions are nested in the package or process. It se

There is a kind of speed called Turtle line, there is a kind of feeling called unbearable, there is a kind of desire called performance improvement, there is a kind of difficulty called the bottleneck. Everyone wants their programs to run quickly, but how hard it is to improve performance is, even getting started. Which of the following is the key to performance improvement? Which segment is the bottleneck of the program running? Do you have to add a period of output before and after each funct

each plan depends on the statistical results collected by the system, but these data are not necessarily the latest. Because you may know more about the database and data content than query optimizer, you can decide a better plan than query optimizer. Using the information provided by query analyzer, you can determine whether the plan provided by query optimizer to the declarative plan is efficient. If you are sure it is not good enough, try modifying the T-SQL statement or using the SQL prompt

simple test. This is a console application, the program is very simple, first 10,000 cycles, output and, and then use LINQ in the list to find 1000 of the value output. Copy Code code as follows: static void Main () { var list = new list var sum = 0; for (var i = 0; i { sum + = i; List. ADD (i); } Console.WriteLine (sum); Find the value use linq:1000 var result = list. Where (P => p.equals (1000)); foreach (var i in result) { Console.WriteLine (i);
