1 Swingbench 简述
1.1 概述
这是Oracle UK的一个员工在一个被抛弃的项目的基础上开发的。目前稳定版本2.2,最新版本2.3,基于JDK1.5。该工具是免费的,可以在作者的网站上自由下载,,并且拥有详细的使用文档。除了Swingbench,作者还开发了两个相关工具:测试数据生成工具DataGenerator和跟踪文件分析工具Trace Analyzer。
Swingbench可以执行4种不同的标准测试(benchmark),拥有三种前端展示方式Swingbench/Charbench/Minibench,其中Charbench是字符模式的,另外两种是GUI模式的。另外还可以通过ClusterOverview可以聚合显示所有的结果。
Swingbench的开发目的主要是用来展示RAC的负载和测试,但也可用于单实例环境。最新的2.3版本开始支持TimesTen内存数据库。

2 Swingbench for windows安装
2.1 解压swingbench压力测试软件
首先在作者网站上下载最新的2.3版本,文件名swingbench230422.zip,大小为9M左右
截压在D:\swingbench230422\swingbench
解压后目录结构如下图所示:
swingbench (Top Level Directory, contains Swingbench.env)
|
+-- bin (Linux/Unix executables)
| |
| +-- sample (sample config files)
| |
| +-- data (data used by benchmarks)
| |
| +-- schema (xml schemas for config files)
|
+-- lib (Java Libraries i.e. *.jar)
|
+-- source (source code & build scripts for transactions)
|
+-- sql (sql scripts used by the wizards to create the schemas)
|
+-- winbin (Windows executables)
2.2 安装JDK
因为运行这个软件需要java支持,我这里下载的jdk 1.5 for windows安装包
介质名为jdk-1_5_0-windows-i586.exe
2.3 安装oracle 10g 客户端
因为在windows下面是客户端,需要安装oci或jdbc连接到p595 aix服务器
介质名为10201_client_win32.zip
2.4 配置环境变量swingbenchenv.bat如下所示:
REM Set the following to reflect the root directory of your Java installation
set JAVAHOME=C:\jdk15
REM Set the following to the directory where you installed swingbench
set SWINGHOME=D:\swingbench230422\swingbench
REM Set the following to the location of your TimesTen install (optional)
set TTHOME=C:\TimesTen\tt70
REM If you don't have the ORACLE_HOME environment variable set uncomment the following and change it to reflect your environment
SET ORACLE_HOME=F:\oracle\product\10.2.0\db_1
set ANTHOME=%SWINGHOME%\lib
set CLASSPATH=%JAVAHOME%\lib\rt.jar;%SWINGHOME%\lib\mytransactions.jar;%SWINGHOME%\lib\swingbench.jar;
REM The following is needed for 10g environments
set CLASSPATH=%CLASSPATH%;%ORACLE_HOME%\jdbc\lib\ojdbc14.jar;%ORACLE_HOME%opmn\lib\ons.jar
REM The following is only needed for 11g environments
set CLASSPATH=%CLASSPATH%;%ORACLE_HOME%\jdbc\lib\ojdbc5.jar
REM The following is only needed for TimesTen environments
set CLASSPATH=%CLASSPATH%;$TTHOME/lib/classes15.jar
3 配置swingbench 连接到数据库,创建表空间,用户,表订单等
3.1 配置tnsnames.ora文件
FSYYK =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 11.4.128.89)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 11.4.128.91)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = fsyyk)
)
)
3.2 运行$SWINGHOME/winbin目录下的oewizard.bat文件
输入jdbc或oci连接方法
jdbc为//主机名或ip地址:1521/sid或services_name
oci为tnsnames.ora中的服务名
以便创建表空间和用户,表结构等
4 运行$SWINGHOME/winbin/swingbench.bat进行压力测试
选择配好的jdbc或oci连接
然后输入用户数,相关订单事物数,就可以进行压力测试了

InnoDBBufferPool reduces disk I/O by caching data and indexing pages, improving database performance. Its working principle includes: 1. Data reading: Read data from BufferPool; 2. Data writing: After modifying the data, write to BufferPool and refresh it to disk regularly; 3. Cache management: Use the LRU algorithm to manage cache pages; 4. Reading mechanism: Load adjacent data pages in advance. By sizing the BufferPool and using multiple instances, database performance can be optimized.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.

MySQL is worth learning because it is a powerful open source database management system suitable for data storage, management and analysis. 1) MySQL is a relational database that uses SQL to operate data and is suitable for structured data management. 2) The SQL language is the key to interacting with MySQL and supports CRUD operations. 3) The working principle of MySQL includes client/server architecture, storage engine and query optimizer. 4) Basic usage includes creating databases and tables, and advanced usage involves joining tables using JOIN. 5) Common errors include syntax errors and permission issues, and debugging skills include checking syntax and using EXPLAIN commands. 6) Performance optimization involves the use of indexes, optimization of SQL statements and regular maintenance of databases.

MySQL is suitable for beginners to learn database skills. 1. Install MySQL server and client tools. 2. Understand basic SQL queries, such as SELECT. 3. Master data operations: create tables, insert, update, and delete data. 4. Learn advanced skills: subquery and window functions. 5. Debugging and optimization: Check syntax, use indexes, avoid SELECT*, and use LIMIT.

MySQL efficiently manages structured data through table structure and SQL query, and implements inter-table relationships through foreign keys. 1. Define the data format and type when creating a table. 2. Use foreign keys to establish relationships between tables. 3. Improve performance through indexing and query optimization. 4. Regularly backup and monitor databases to ensure data security and performance optimization.

MySQL is an open source relational database management system that is widely used in Web development. Its key features include: 1. Supports multiple storage engines, such as InnoDB and MyISAM, suitable for different scenarios; 2. Provides master-slave replication functions to facilitate load balancing and data backup; 3. Improve query efficiency through query optimization and index use.

SQL is used to interact with MySQL database to realize data addition, deletion, modification, inspection and database design. 1) SQL performs data operations through SELECT, INSERT, UPDATE, DELETE statements; 2) Use CREATE, ALTER, DROP statements for database design and management; 3) Complex queries and data analysis are implemented through SQL to improve business decision-making efficiency.

The basic operations of MySQL include creating databases, tables, and using SQL to perform CRUD operations on data. 1. Create a database: CREATEDATABASEmy_first_db; 2. Create a table: CREATETABLEbooks(idINTAUTO_INCREMENTPRIMARYKEY, titleVARCHAR(100)NOTNULL, authorVARCHAR(100)NOTNULL, published_yearINT); 3. Insert data: INSERTINTObooks(title, author, published_year)VA

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
