Challenges

The Parts Data Management (PDM) Project encompassed the full life cycle of a SAP MDM project to support centralized control, governance and maintenance of MRO (Maintenance Repair and Operating) part records. Hardware was purchased and installed to handle the landscape of Development, Test and Production environments. An implementation partner was contracted to help ArcelorMittal configure the MDM data repository, build the web based “Portal” screens, workflow and interface to 11 legacy CMMS/Purchasing systems.

The focus of all of the testing was against the web based “Portal” applications.
Application tested: MDM Portal iViews

Protocols tested: http.

Our project team attempted a go live event on September 22, 2008 for the PDM project (as described above) and we found that we had to back out of the new application and revert back to the old system and old processes. The Portal Server had performance problems from heap memory increasing rapidly and not flushing properly. Had we stress tested before that go live attempt we would have found this problem and worked towards resolving it.

Our successful go live event was on November 24, 2008.

Solution

ArcelorMittal searched for a stress testing tool to test our MDM Portal web applications to verify that the changes made to the custom MDM iViews (coded in Java) corrected the performance and heap memory issues we previously had on our Portal Server.

There was no money included in the project budget for an expensive solution and there was no time to contract another third party to help us through this issue. Our searches lead us to NeoLoad.

Janynne Henry quickly learned how to configure and run NeoLoad and our project team worked very close with throughout all of our stress testing events. Our MDM TEST environment was made to replicate or MDM PROD environment exactly, CPU, Memory, Interface, etc… One of our tests involved approximately 20 users running controlled testing scripts while Janynne was ramping the number of virtual users up to 250, then back down.

The tests were successful and gave our project team the confidence to move forward with our go live event on November 24, 2008.

Résultats du test et valeur ajoutée

The main benefits for using NeoLoad were are follows:

  • Low cost solution
  • Ease of use
  • Stress test up to 250 concurrent virtual users
  • Provided confidence needed by the project team to move forward with the go live event.
