Embodiment Construction

[0086] Below with reference to accompanying drawing, the present invention is further described by specific embodiment:

[0087] A memory pressure testing method of a Linux server, the testing method process is:

[0088] 1) On the Linux server that needs memory stress testing, copy the MemTest script and the memtester-4.3.0.tar.gz file to any directory, such as the / root directory;

[0089] 2) Give the script file executable permission: #chmod 777 MemTest;

[0090] 3) Execute the script program: #. / MemTest;

[0091] (1) When the program is running, it will first check whether the memtester tool has been installed. If not, install it, if it is already installed, go to the next step.

[0092] (2) Calculate the test parameters. Read the number of processor cores of the current server. In this example, it is a logical core, that is, a virtual core including hyperthreading, and records it as the variable CPU. Read the current remaining physical memory every 10s, record it as M...

Abstract

The invention discloses a test method for the memory pressure of a Linux server. The process of the test method comprises the steps of 1, copying a MemTest script and a memtester-4.3.0.tar.gz file to any catalog on a Linux server needing to be subjected to the memory pressure test; 2, giving the script and the file an executable right: #chmod777MemTest; 3, executing a script program: #. / MemTest; 4, analyzing a test result. By adopting the method, third party software is not required, and the method is easy and feasible; the method is compiled by using a Shell script, is strong in universality and can test in a cross-platform mode; the optimal test parameter is automatically calculated, and the method supports the self definition circulation times, and is suitable for different test environments; multi-process concurrency is realized, and the test efficiency is high; the program has no residual files and has no influence to a system.

Description

technical field [0001] The invention relates to a memory pressure test method of a Linux server, a pressure test method for a Linux server when judging a memory channel failure, and a copying test method for checking the working stability of the memory. technical background [0002] With the continuous development of memory technology, the capacity of a single memory becomes larger and larger. While meeting the growing program running space of the server business, it also makes our work of testing memory performance and stability more and more cumbersome. Usually, when the amount of business calculation is not large, the memory access efficiency and accuracy are ideal. However, as more and more users access the server, a large amount of data and instructions interact more frequently with the CPU through the memory, increasing the pressure on the memory, and the overall stability of the server will be greatly tested. However, in our actual testing process, it is difficult to...
