Hiperstation的大型服务器，您可以记录，审查和重播分布式应用到z / OS的组件的接口。
由于分布式通信是无形的用户界面，它们是很难测试。如果数据不正确流动，严重的，可能很难找到错误和可能发生的故障。 Hiperstation的大型服务器可帮助分析和自动化SNA和TCP / IP数据之间的交流不同的平台，使其可以实现：
test server application changes without the user interface
simulate server responses during a user interface test
test changes to the operating system, language enviroment or subsystems
implement consistent, repeatable server regression tests
conduct pre-production performance testing for applications and systems software
confirm disaster recovery setup
audit server activity for appropriate access
provide hidden details to help desk and support personnel.
