㈠ 定义
ORION(Oracle I/O Calibration Tool)是Oracle提供的、用于测试存储系统性能瓶颈
由于 ORION 是一个独立工具,用户不需要创建和运行 Oracle 数据库
ORION的使用非常简单,从官网上down下来的包直接解压就可以使用
下载地址
解压:
# gunzip orion_linux_x86.gz
㈡ 优点
● 不需要运行Load Runner以及配置大量的虚拟用户
● 不需要运行Oracle数据库,以及准备大量的测试数据
● 测试结果更具有代表性,如随机IO测试中,该软件可以让存储的命中率接近为0,更仿真出了磁盘的真实的IOPS
而load runner很难做到这些,最终的磁盘IOPS需要换算得到
● 可以根据需要定制一定比例的写操作(默认没有写操作),但是需要注意,如果磁盘上有数据,需要小心数据被覆盖掉
㈢ 输出文件
ORION 执行结束会输出5个文件:
●
●
●
●
●
●
㈣ 三个强制参数
运行ORAION必须包含run,testname,num_disks 三个参数
● run
Type of workload to run(simple, normal, advanced)
simple - tests random 8K small IOs at various loads,then random 1M largeIOs at various loads.
normal - tests combinations of random8K small IOs and random 1M large IOs
advanced - run theworkload specified by the user using optional parameters
● testname Name of the test run
● num_disks Number of disks (physicalspindles)
㈤ 一次简单的测试
ORION的执行需要一个参数文件,,用于指定测试的磁盘
# cat /dev/sda1 > rocky
# cat /dev/sda2 > rocky
# ./orion_linux_x86 -run simple -testname rocky -num_disks 1
测试的结果会生成以上所说的5个文件
