183. 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。

183.1. 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。

下载地址: https://www.oracle.com/downloads/server-storage/vdbench-source-downloads.html

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

出现csh找不到的问题，原因是： + vdbench 5.04.05的vdbench脚本是c shell script文件。解决办法是：

方法1：安装csh

sudo apt install csh

方法2：使用最新版本 5.04.07 【建议】

可以看到最新的5.04.07使用的是bash script。

me@ubuntu:~/vdbench50407$ file vdbench
vdbench: Bourne-Again shell script, ASCII text executable

183.2. 使用vdbench 5.04.05¶

出现java版本检测不合法的问题。

me@ubuntu:~/vdbench504$ ./vdbench -t


Vdbench distribution: vdbench504
For documentation, see 'vdbench.pdf'.

*
* Minimum required Java version for Vdbench is 1.5.0;
* You are currently running 10.0.2
* Vdbench terminated.
*
*
*

CTRL-C requested. vdbench terminating

183.3. 使用vdbench 5.04.07¶

在vdbench 5.04.07上没有出现java版本报错的问题。查看源码，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.

183.4. vdbench在ARM服务器上出现共享库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
linux/linux64.so: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, BuildID[sha1]=34a31f32956f21153c372a95e73c02e84ddd29f8, not stripped

183.5. 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

参考如下修改方法

diff --git a/Jni/make.linux b/Jni/make.linux

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。

183.6.1. 详细测试¶

配置的文件中的

General
Host Deinition(HD)
Replay Group(RG)
Storage Definition(SD)
Workload Definition(WD)
Run Definition(RD)

必须顺序出现。一个run指的是，RD执行的WD

Master和Slave， Vdbench以一个或者多个JVM运行。由用户运行的JVM是master，负责解析参数和报告。Slave可以运行在本机，也可以在远程主机执行。
