SAP应用程序的负载利记手机app

As any enterprise expands, its internal processes naturally become more complicated. In 2015, growing business prompted one agricultural company to put its internal operations in order.

要做到这一点, they began centralizing disparate databases and switched to an automated SAP control system. To ensure the platform’s reliability, the customer hired 性能 Lab to conduct load testing.

利记手机app的客户是肉类生产商. 它是食品的主要生产商之一 家禽、猪肉及加工食品 肉类产品.

因此,性能 Lab面临以下任务:

Conduct load testing of an SAP ERP system to make the customer confident about the speed of critical business processes.

心里有个项目?

没有比利记手机更适合QA解决方案的地方了.

利记手机app是怎么做到的?

模仿购买的生命周期, 销售, 物流, and related financial processes at client’s eight production plants, 利记手机app开发了加载脚本和场景.

We emulated the user load on the SAP ERP system using such load testing tool like HP LoadRunner. The load was supplied from workstations located at the production plants.

During the project, the 性能 Lab team encountered several difficulties. Below we will describe these challenges and how they were overcome.

  • The customer was still updating the system while we developed the load scripts. 因此,必须每周执行额外的利记手机app运行.

  • We had to arrange for various pieces of data to be passed between the scripts. 要做到这一点, we used Virtual Table Server, which comes with HP LoadRunner.

  • 利记手机app涉及到使用外部系统模拟器, 第三方承包商对此负责. These systems were operated manually, so their behavior was unpredictable. 尽量减少潜在的困难, we joined forces with the customer and established effective communication with the contractors. This made it possible to immediately bring in the relevant people in order to resolve 问题.

  • The scripts were developed by a team of remote testers, so we needed to coordinate their efforts. We accomplished this by introducing the GIT version control system and putting together a system to assign those responsible for script development. This system allowed, among other things, tracking of development status.

    • A multi-stage documentation approval system also complicated the work of the 性能 Lab team. Consequently, we produced a concise load testing methodology for the customer’s employees.

这个项目揭示了什么?

该应用程序是为特定设备开发的. 利记手机app遇到的第一个问题是它的唯一性. 这款名为“大力神”(Hercules)的平板电脑无法出售. It was a kind of a custom device, and we couldn’t use similar devices.

性能 optimization based on an analysis of the test results reduced the time required to complete the main 物流 business scenario by more than 2 times and increased the speed of individual transactions by up to 8 times.

We also identified a working configuration for printing that was acceptably fast for the customer, 并在负载下验证了其与外部系统的集成.

性能 Lab’s work helped the customer make an informed decision about deploying
将系统导入生产环境.

但这还不是全部.

This experience between 性能 Lab and the client was so productive that a few years later we carried out another joint project.

This time we performed load testing of a SAP system for warehouse management. 利记手机app的团队同时面临着几个任务:

01

验证业务流程没有被中断

02

Be sure that the volume of documents required by the customer can be processed

03

确定系统满足性能要求的程度.

04

Identify performance-limiting factors and formulate recommendations on how to optimize performance.

Despite the fact that 性能 Lab had by that time already accumulated skills in testing SAP systems, 这个项目也有 问题.

与第一个负载利记手机appSAP应用程序一样, the customer’s system was still in development when the project started. So we again had to perform individual stages of the project several times.

此外, the system actually had to be adjusted to support load testing in SAP, which required us to establish effective communication with the developers.

情况变得复杂了 这个项目开始晚了 而且事实上 利记手机app把一部分工作交给了客户, 谁, 事实证明, did not have the knowledge and skills required to accomplish that work. These difficulties required the utmost concentration of our efforts and well thought-out time management.

利记手机app这次成功了吗?

作为利记手机app的结果, we were able to prove that the system’s business processes are not interrupted and that the volume of documentation required by the customer can be processed.

However, the system only partially satisfied the performance requirements. 开发人员随后能够修复一些东西, and the customer accepted the rest as an additional risk during deployment.

性能 Lab discovered several factors limiting system performance. For example, we discovered locking taking place during document processing. Following our recommendations, the developers were able to eliminate some of them.
