3 Weeks to Go-Live SAP Performance Testing Case Study PDF

This is the downloadable PDF version of Merito's case study on validating a $50M SAP deployment for go live in three weeks. It covers the load, stress and spike testing strategy, the mid engagement pivot to OpenText LoadRunner Enterprise, and how the team solved SAP session token, tool memory and vendor licensing issues under a fixed deadline.

What to expect:

  • Walks through a full load, stress and spike testing strategy built for a $50M SAP deployment in three weeks with no existing baseline.
  • Covers the mid engagement pivot to OpenText LoadRunner Enterprise, VuGen and Analysis after a previously selected tool could not be licensed in time.
  • Details how SAP's dynamic session tokens and VuGen's 32-bit memory limits were solved with custom correlation and cleanup work.
  • Shows how SLA thresholds were built from scratch using single-user baselines combined with SAP's own benchmarks.
  • Includes the before and after picture of what the customer had going into go live versus what they had three weeks later.
