There is a system. Diagnostics namespace in the. NET class library, which provides some class libraries that interact with system processes, event logs, and performance counters. It includes two very useful classes for developers-Debug and trace. This article introduces some basic functions of these two classes to improve the development efficiency of developers.Debug classDebugging programs are common to every programmer. However, we often encounter
1. View V$diag_info view, can see the location of the trace file, the specific name and other information.Name column, Diag Trace is where the 11g trace file is locatedThe Default trace file is the trace file name of the current session2. Query can generate
Sap r/3 provides standard abap SQL tracking tools. Use T-code: st05 To Go To The tracking setting screen:
In the trace modes area, select the scope of the trace to be performed on the sap r/3 server: SQL trace: traces the SQL statements that have been filtered by the AP server. Enqueue trace:
Anyone who has done ASP. NET development knows that the TRACE command is a very useful method for tracking and debugging pages. There are two ways to use trace:1. Configure the TRACE command in Web. configAfter this command is configured, enter http: // host address/trace. axd in the address bar of the IE browser to vi
Unlike the local C + + maintenance heap, the dynamically allocated memory in C++/CLI is maintained by the CLR. When a heap is not needed, the CLR automatically deletes it for recycling, while the CLR can automatically compress the memory heap to avoid unnecessary memory fragmentation. This mechanism avoids memory leaks and memory fragmentation , which is referred to as garbage collection, while this kind of heap managed by the CLR is called the CLR heap. It is created by the operator gcnew.

Recently, a set of database directories were suddenly used with an alarm. It was found that the TRACE Directory was in high usage. It was found that a cdmp * directory is generated every minute in the bdump directory, and each directory contains a large number of files, this is a set of oracle 11.2.0.3 rac on hpux 11.31 databases. If dump event is not enabled in the system, it may be a bug, which is a simple record here.Oracle @ anbob2:/oracle/app/ora
LTE user documentation(if there are inappropriate places, please correct me!) )7 using Fading TraceThis section describes how to use the fading traces in LTE emulation. (1) Generate Fading tracesgenerate fading traces by using the code provided by the dedicated MATLAB script (/lte/model/fading-traces/fading-trace-generator.m). The script contains a typical taps configuration for 3 3GPP scenes (for example, pedestrians, vehicles, and cities, defined in
SQL trace is mainly used to monitor the SQL of databases and monitor and adjust the applications acting on data at any time.Program. For example, the ERP system has many application interfaces and involves many underlying operations. If you want to know which SQL statements are executed in the underlying database for operations on a specific interface, you need to enable the trace function to record these S
In the process of diagnosing database system performance, the oracle| process always involves tracking inefficient SQL statements and now makes a simple summary of how to track SQL statements. Right to make a use of it.
If we can modify the source code of the application system, we can add the following statement directly to the program:
1 ALTER session SET TIMED_STATISTICS=TRUE/* Applies to Oracle 7.3 Version/*
2 ALTER session SET max_dump_file_size=unlimited/* Applies to Oracle 7.3 Version/

VLAN information and update their own VLAN database based on the VLAN information received. Whether the switch is in the same domain is distinguished by a domain name, such as the domain name CCIE and the domain name CCIE belong to the same domain, and the domain name CCIE and the domain name Cisco belong to a different domain. The domain name of the default switch is empty, but the most important thing to remember is that if your own domain is empty, then it is the same as any non-empty domain

Find out the call stack of the program trace can know who called this interface, but also quickly learn the process of invoking the program, very practical. However, it is important to note that it cannot be used in formal code, only for debugging purposes, and this very expensive source can also cause log flooding.Here's how to print out the program call Trace in the Android java/c++/c program, and if you

These two functions are mainly used to debug and track the program, and some related results can be output to the specified place. In. NET's debug mode, Debug and trace are output, and in release mode, only trace is opened by default, and you can turn trace off by setting.

In the computer architecture, the simulator is an important and effective tool. GEM5 integrates the advantages of Gem and M5, which is simple and convenient to use. Including the SE mode and fs mode, SE mode is to run our compiled program in GEM5, can get data such as CACHE,CPU status, FS mode can simulate the operating system, we can load our own modified Linux kernel to run on the Buddies. The following describes the SE mode of using GEM5 to run the compiled arm executable file. Get the retrie
