There is a system.diagnostics in the. NET class Librarynamespace, which provides some class libraries that interact with system processes, event logs, and performance counters. It includes two class--debug classes and trace classes that are useful to developers. This article describes some of the basic uses of these two classes, which are designed to improve the development efficiency of a broad range of developers.Use the Debug class to help debugDeb
http://blog.itpub.net/16832682/viewspace-1249765/Recently, due to the issue of PL/SQL performance on the project, it is necessary to tune the concurrency programs that have been developed. An important step in tuning is to get the trace file for the concurrent program to know which SQL has a problem.Here's a summary of how to get the trace file for the Concurrency program:1. Start the tracking function on t
The first time FD was installed, it encountered an extremely serious problem. During installation and configuration, I followed the instructions step by step, and the debug Flash Player was also installed. However, nnd does not output trace information. It is also inexplicable to ask questions in the group. But fortunately, I was born to be smart. After two hours, I finally solved the problem. (La la ......)The method is as follows:1.

Reprinted from: Http://blog.csdn.net/oujunli/article/details/9102101#replyFor people engaged in Android development, encountering ANR (application not responding) is a more common problem. In general, if there is a ANR occurrence, the system will generate trace files in the/data/anr/directory, by analyzing the trace file, you can locate the cause of the ANR. There are many reasons for the ANR, such as high

In the last lecture, we introduced the display of place names by invoking an external XML file. In this talk, we explain how to use the trace function of the Flash ActionScript code to implement interactive map background to quickly mark the work of geographical names.
Understanding the Trace function
First, let's take a look at the trace

Each server and background process writes to a trace file. When a-process detects an internal error, it writes information about the error to its trace file. The file name format of a trace file is Sid_processname_unixpid.trc, where:SID is the instance system identifierProcessName is a three or four-character abbreviated process name identifying the Oracle Databa

first, understand the difference between Debug and trace:
1. What is the difference between Debug.Write and trace.write? Which one should be used when.
The Debug class provides a set of methods and properties that help you debug your code. The Trace class provides a set of methods and properties that help track code execution, which is commonly used to record the execution of a program without interruptin
The matrix (phalanx) trace operation returns the and of the diagonal elements of the matrix:
Trace operations are useful for a number of reasons. With the summation notation, some matrix operations are difficult to describe, and the matrix multiplication and trace operation symbols can be clearly expressed. For example Matrix F-norm (Frobenius norm):
Trace files are generated by each background process, and key actions are logged in the alert log, including:• All start and close commands, including intermediate commands, such as ALTER DATABASE mount• All internal errors for the instance (ORA-600 error, can only be reported to Oracle support solution)• Any detected data file block corruption• Any deadlocks that have occurred• All operations that affect the physical structure of the database, such a
. The reduction of failrate mainly relies on improving the accuracy of branch prediction. You can add some information in the program to tell the compiler that branch has a higher probability, but it is very difficult to further improve it. The appearance of Trace Cache can reduce predicttime and failpenalty.
