Load Testing for ERP Implementation Go-live

Load Testing improved stability & performance in preparation for go-live on a large JD Edwards implementation.

The scenario

A client was preparing for go-live on a large JD Edwards implementation.  Having changed database, web and more they needed to know that the system would survive 400 users logging in on day one. Myriad IT was asked to help.

 

Dynamic testing & monitoring solution

Over a period of 10 days, Myriad IT simulated 20 of the client’s top processes using Oracle Application Testing Suite (OATS).  The OATS scripts were programmed dynamically to read dynamic data from tables & spreadsheets and were then run in a range of concurrencies to simulate “a day in the life” processing.  The workload was a mixture of batch and interactive processing.

Myriad IT co-ordinated the tests, and checked the system before and after each test to ensure transactions hit the database. Additionally, Myriad IT configured monitoring tools to understand exactly what was happening on all of the servers.

Plugins for Enterprise Manager 12c were used to extract the real-time performance data.

 

Improved stability & performance

Myriad IT gathered system data and performance metrics from OATS to deliver a report to the client. During the course of testing, numerous bottlenecks were identified and quickly resolved. Myriad It made over ten (10) system changes (hardware allocations & configuration changes) to improve stability and performance of the ERP.

 

Performance gains & peace of mind

Using the load test results, Myriad IT was able to double the throughput of JD Edwards in comparison to the initial configuration values i.e.  performance was improved twofold.

Knowing in advance that the system could handle the load meant that the go-live was a huge success for the client. The client is now looking at more testing services from Myriad IT, including functional test automation.
