大家都知道orion这个软件是oracle自带的，但是在网上只有11.1之前的，其功能不足够强大，如果要进行I/O测试，并且本机没有oracle怎么办？只能另想办法了这里有一个好的办法推荐给大家：
首先需要几个包：
在$ORACLE_HOME/lib目录下找 libclntsh.so.11.1, libcell11.so, libskgxp11.so and libnnz11.so这四个包脚本如下运行：./orion -run advanced -testname felix -size_small 8 -size_large 1024 -type rand -simulate concat -write 0 -duration 10 -matrix basic -num_disks 7
ORION: ORacle IO Numbers -- Version 11.2.0.3.0

Calibration will take approximately 8 minutes.
Using a large value for -cache_size may take longer.
