I would like to share with you how to use the ORION Ithumb O testing tool. I believe most people don't know much about it, so share this article for your reference. I hope you can learn a lot after reading this article. Let's learn about it together.

1. Introduction

No need to create and run Oracle database

A stand-alone tool for calibrating the performance of the storage system Imaco for Oracle databases

The test results are representative: for example, in the random IO test, the software can make the hit rate of the storage close to 0, and simulate the real IOPS of the disk.

2. Use

-required parameters

-optional parameters

Num_streamIO: add this parameter to simulate parallel operations. Specifies the degree of parallelism of the plan. A good starting point is the number of CPU * the number of threads in a CPU.

-num_small

Specify the number of processes when testing small IO

-num_large

Specify the number of processes when testing large IO

Matrix: use point to simulate a single continuous workload, or use col to simulate an ever-increasing large continuous workload.

The desired form of test results when using non-simple/normal mode

Basic: equivalent to the output of run-simple, but can be more customized

Detailed: equivalent to the output of run-normal, but can be more customized

Point: only measure the performance of a given num_small,num_large

Col: the large IO that measures only the column of a given num_ small value

Row: the small IO that measures only the row with a given num_ log value

Max: use num_small,num_large as the maximum value of horizontal and vertical coordinates to test the values of all combinations in the Nimm matrix

3. Give an example

4. Result analysis
