即将上线的数据库如何来评估其性能呢,swingbench是除了Benchmark Factory for Databases的不二之选,可以用短小精悍来形容,而且完全免费,也不用成天到晚google注册码,还等什么呢,,赶紧来瞧瞧......
一、swingbench介绍
是JAVA程序,当前分为两个版本,一个是2.3,一个是2.4,支持windons/linux/unix平台,测试了一下win7 64平台,运行不太稳定
支持Oracle 单实例以及Oracle RAC,支持Oracle 10g,11g。运行环境需要安装oracle 客户端或者instant client
包含OrderEntry, SalesHistory, CallingCircle and StressTest几个种子数据库,具体描述参见作者网站
软件由load generator,coordinator,cluster overview组成,可以生成负载以及事务,响应时间并以图表方式展示
从作者网站下载swingbench,
如果下载最新的2.4版,则需要安装java(6) 1.6或以上版本,无需修改任何配置文件。
如果下载2.3版本的则,则需要安装java 1.5或以上版本则需要修改swingbench.env配置文件
由于2.4的版本直接运行即可(安装java 6以及Oracle客户端),因此本文以2.3版本进行描述。
二、安装前的准备工作
1、确认安装的平台与java,oracle相关配置
oracle@SZDB:~> cat /etc/issue #查看系统版本
Welcome to SUSE Linux Enterprise Server 10 SP3 (x86_64) - Kernel \r (\l).
oracle@SZDB:~> java -version #使用这个方式即可确认jave当前的版本
java version "1.5.0_22"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_22-b03)
Java HotSpot(TM) 64-Bit Server VM (build 1.5.0_22-b03, mixed mode)
SZDB:/ # find / -name java |grep jdk #查看java路径
/usr/java/jdk1.5.0_22/bin/java
/usr/java/jdk1.5.0_22/jre/bin/java
/users/oracle/OraHome10g/jdk/bin/java
/users/oracle/OraHome10g/jdk/jre/bin/java
oracle@SZDB:~> env | grep ORACLE_HOME
ORACLE_HOME=/users/oracle/OraHome10g
2、安装配置swingbench
使用ftp工具将下载的zip文件上传导linux服务器,本文使用的为winscp。
上传解压后的路径及文件如下:
oracle@SZDB:~/robinson/swingbench> pwd
/users/oracle/robinson/swingbench
oracle@SZDB:~/robinson/swingbench> ls
bin lib README.txt source sql swingbench.env swingbenchenv.bat winbin
oracle@SZDB:~/robinson/swingbench> vi swingbench.env
#!/bin/bash
# Set the following to reflect the root directory of your Java installation
export JAVAHOME=/usr/java/jdk1.5.0_22 #修改此路径为正确的路径
# Set the following to the directory where you installed swingbench
export SWINGHOME=/users/oracle/robinson/swingbench #修改此路径为正确的路径
# Set the following to the location of your TimesTen install (optional)
export TTHOME=/opt/TimesTen/tt70
# If you don't have the ORACLE_HOME environment variable set uncomment the following and change it to reflect your environment
export ORACLE_HOME=/users/oracle/OraHome10g #修改此路径为正确的路径
#
export ANTHOME=$SWINGHOME/lib
export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:$ORACLE_HOME/lib:$TTHOME/lib
export CLASSPATH=$JAVAHOME/lib/rt.jar:$JAVAHOME/lib/tools.jar:$SWINGHOME/lib/mytransactions.jar:
${SWINGHOME}/lib/swingbench.jar:$ANTHOME/ant.jar:
# The following is needed for 10g environments
export CLASSPATH=$CLASSPATH:$ORACLE_HOME/jdbc/lib/ojdbc14.jar:$ORACLE_HOME/opmn/lib/ons.jar
# The following is only needed for 11g environments
export CLASSPATH=$CLASSPATH:$ORACLE_HOME/jdbc/lib/ojdbc5.jar
# The following is only needed for TimesTen environments
export CLASSPATH=$CLASSPATH:$TTHOME/lib/classes15.jar
3、安装soe schema
启动Xmanager - Passive,也可以直接remote到linux后执行命令以期用GUI界面
oracle@SZDB:~/robinson/swingbench> export DISPLAY=192.168.7.133:0.0
oracle@SZDB:~/robinson/swingbench> cd bin
oracle@SZDB:~/robinson/swingbench/bin> ./oewizard #使用GUI向导安装oe schema
soe@SYBO2SZ> @dba_tables_user #检查安装soe的结果
Table Name Tablespace Last Analyzed # of Rows

Adding MySQL users through the PHP web interface can use MySQLi extensions. The steps are as follows: 1. Connect to the MySQL database and use the MySQLi extension. 2. Create a user, use the CREATEUSER statement, and use the PASSWORD() function to encrypt the password. 3. Prevent SQL injection and use the mysqli_real_escape_string() function to process user input. 4. Assign permissions to new users and use the GRANT statement.
