Use of Oracle SQL Performance Analyzer With SPA, you can play a specific SQL or the entire SQL load based on various types of changes (such as initialization parameter changes, optimizer statistics refreshing, and database upgrades), and then generate a comparison report, helps you evaluate their impact. In versions earlier than Oracle Database 11g, I had to capture all SQL statements, trace and run these statements, and then get the execution plan-th

The use of PAL tools is similar, online to see this article is very good, direct translation over.If you have Exchange performance issues in the past, you know that there are many variables that affect exchange overall performance, and sometimes it takes a long time to find the root cause of the problem because they can become quite complex.If you are looking for a detailed report with a chart function, it is the performance Analyzer Tool (PAL).Pal is
First, we all know that the programming language needs to be compiled before it executes, so that the code can be converted into a machine-recognized language, and this process is compiled.So how does it compile?Java is compiled in the JVM virtual machine, and JavaScript is compiled in the JS engine.The process of compiling is generally three steps:1. Word Segmentation/Lexical analysis (tokenizing/lexing)This process will break down the string into chunks of code that are meaningful (for progr
Ncdu-ncurses library-based disk usage Analyzer Ncdu (NCurses Disk Usage) is an interface based on the du command of the Ncurses library. It provides a quick and easy-to-use interface through the well-known du command. It displays the percentage of disk usage and allows you to navigate between directories using the ncurses library. Install Ncdu has been transplanted to most linux distributions and can be installed from the official repository. Arch/Man
ObjectiveIn the ordinary course of work, sometimes encounter outofmemoryerror, we know that encountered error generally indicates that the program has a serious problem, may be catastrophic. So it is very important to find out what causes outofmemoryerror. Now we introduce the Eclipse Memory Analyzer tool (MAT) to resolve the challenges we face. If not stated, this article uses the Java 5.0 on Windows XP SP3 environment.Why use Mat?Previously, I think
The lexical analyzer is to scan a program to determine whether it is a keyword, identifier, constant, delimiter, operator. Generally divided into one character and the classic V;Here I use the classic V, this lexical parser is written in C + +;/*Reserved words | Keyword: 1operator | operators: 2Delimiter: 3Identifier: 4Constant: 5No recognition: 6*/The main code is:#include Operation Result:C + + Lexical analyzer

The questions and possible answers are now recorded as follows:Is there a language that is not suitable for using Flex/lex as a lexical parser? O ' REILLY Flex and Bison (Chinese version), question 5, 24th. Ask for advice! I personally think that lexical analysis, since it is to divide the input stream into a meaningful mark (see Long
Ext.: http://tivan.iteye.com/blog/1487855ObjectiveIn the usual development, testing process, or even production environment, sometimes encountered Outofmemoryerror,java heap overflow, which indicates that the program has serious problems. We need to find the cause of outofmemoryerror. There are generally two situations:1, memory leaks, the object is dead, can not be automatically recycled through the garbage collector, by finding out the location of the code and the cause of the leak, to determi
When it comes to sniffer software, you may soon be reminded of Nai's sniffer Pro. Although Sniffer Pro is rich in features, it is somewhat elaborate to operate. Again here I introduce a simple and practical sniffer software, that is our protagonist today: Iris traffic Analyzer. I'm going to use iris traffic Analyzer 4.0.7 as the blueprint for a few simple examples to tell you about Iris. one. Introd
server| Query Analysis These days in the web development, often need to connect SQL Server, but SQL Server is the server on the Internet, the service provider gave a sqlconnectionstring, However, in the connection string found that the SQL Server does not use the default 1433 port, so I would like to Query Analyzer should not log on, the results verified that my idea is right. In this case, you can only write a simple SQL execution program in the prog

First, the purpose of the experimentThrough the design and debugging a specific lexical analysis program, deepen the understanding of the principle of CI analysis. In the process of scanning the programming language source program, it is decomposed into lexical analysis methods of all kinds of words.Compiling a read word process, from the input of the source program, the identification of the individual meaning of the word, that is, the basic reserved words, identifiers, constants, operators, se
