vdbench
Oracle维护的一个磁盘IO性能工具，用于产生磁盘IO 负载测试磁盘性能和数据完整性。
使用前准备
下载解压即可使用。一般不需要编译，如果运行环境存在，可以直接运行。当在ARM服务器上执行时会遇到一些问题，这里介绍如何解决。
测试运行环境：
#给脚本赋予运行权限
chmod +x vdbench
#执行测试
./vdbench -t
me@ubuntu:~/vdbench50407$ ./vdbench -t
-bash: ./vdbench: /bin/csh: bad interpreter: No such file or directory
如果出现csh找不到的问题，需要安装csh。
- vdbench 5.04.05的vdbench脚本是c shell script文件。
- vdbench 5.04.07是bash script。
建议使用5.04.07。
me@ubuntu:~/vdbench50407$ file vdbench
vdbench: Bourne-Again shell script, ASCII text executable
sudo apt install csh
如果缺少jre，安装jre
sudo apt install default-jre
vdbench 5.04.05
出现java版本检测不合法的问题。
me@ubuntu:~/vdbench504$ ./vdbench -t

vdbench 5.04.07
已经移除java版本检测checkJavaVersion();。移除原因作者未说明，详细请参考版本发布说明。
// Removed as per 50407 because of java 1.10.x
//checkJavaVersion();
//....
private static void checkJavaVersion()
{
if (common.get_debug(common.USE_ANY_JAVA))
return;
if (!JVMCheck.isJREValid(System.getProperty("java.version"), 1, 7, 0))
{
System.out.print("*\n*\n*\n");
System.out.println("* Minimum required Java version for Vdbench is 1.7.0; \n" +
"* You are currently running " + System.getProperty("java.version") +
"\n* Vdbench terminated.");
System.out.println("*\n*\n*\n");
System.exit(-99);
}
}
版本发布说明oracle vdbench 50407rc29
50407rc29
The check to make sure you are running java 1.7 or higher has been removed.
ARM共享库aarch64.so问题
在ARM服务器上，会出现共享库不匹配的问题。

原因是vdbench根目录下/linux/linux64.so是为x86编译的,需要重新编译linux64.so
me@ubuntu:~$ file linux/linux64.so

ARM版本的aarch64.so编译
下载，解压源码包： 下载地址 需要同意license
unzip vdbench50407.src.zip
进入src创建linux目录
cd src/
mkdir linux
进入Jni修改make.linux。主要修改:
+ 修改vdb为源码包src的路径
+ 修改java为jdk路径。一般在/usr/lib/jvm/下
+ 去除-m32和m64选项
cd Jni/
vim make.linux
修改前：
vdb=$mine/vdbench504
java=/net/sbm-240a.us.oracle.com/export/swat/swat_java/linux/jdk1.5.0_22/
jni=$vdb/Jni
INCLUDES32="-w -m32 -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
INCLUDES64="-w -m64 -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
gcc -o $vdb/linux/linux32.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o -lm -shared -m32 -lrt
gcc -o $vdb/linux/linux64.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o -lm -shared -m64 -lrt
修改后：
vdb=/home/me/vdbench50407src/src/
java=/usr/lib/jvm/java-11-openjdk-arm64/
jni=$vdb/Jni
INCLUDES32="-w -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
INCLUDES64="-w -DLINUX -I$java/include -I/$java/include/linux -I/usr/include/ -fPIC"
gcc -o $vdb/linux/linux32.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o -lm -shared -lrt
gcc -o $vdb/linux/linux64.so vdbjni.o vdblinux.o vdb_dv.o vdb.o chmod.o -lm -shared -lrt
执行make.linux，会在src/linux/下生成linux32.so和linux64.so文件，这里我们只需要使用到64位的文件。重命名linux64.so并复制到二进制包（注意不是源码包）的linux/目录下即可。
