Overview
This is initial report for EBSCONET orders renewal workflow testing
. The purpose of this document is to highlight KPI KPIs of EBSCONET workflow, find possible bottlenecks/ issues. Define baselineJira Legacy server System JIRA serverId 01505d01-b853-3c2e-90f1-ee9b165564fc key PERF-285
Summary
[ A bulleted-list of the most important and relevant observations from the test results. What are the most important things the readers need to know about this testing effort? Some suggestions
- Comparison to previous test or release of response times or API durations
- Any notable changes
- Particular response time or durations
- Service memory and/or CPU utilization
- RDS memory and/or CPU utilization
- Other interesting observations

Recommendations & Jiras (Optional)
[ If there are recommendations for the developers or operations team, or anything worth calling out, list them here. Also include any Jiras created for follow-up work], and define the baseline performance for this workflow since it hasn't been tested before. EBSCONet is a client application that calls edge-orders to renew orders. The tests simulate EBSCONet calling edge-orders by issuing calls to retrieve a Purchase Order Line (POL) and updating it with relevant information for renewal.
Summary
During testing we've find several issues:
- NullPointerException
- Internal server error
No memory leaks were found.
High level results:

Recommendations & Jiras
Ticket to handle NullPointerException Which is reproducible even with 2 users.Jira Legacy server System JIRA serverId 01505d01-b853-3c2e-90f1-ee9b165564fc key MODEBSNET-56
Ticket to handle internal server error .Jira Legacy server System JIRA serverId 01505d01-b853-3c2e-90f1-ee9b165564fc key MODEBSNET-57 - We have noticed that mod-orders-storage has allocated only 128 CPU units. It's better to increase CPU units value of mod-orders-storage based on CPU utilization (at least 3x times)

Methodology/Approach
According to EBSCONET order renewal integration testing we have designed test containing two calls [get] /orders/order-lines/${polineNumber}?type=EBSCONET&apiKey=${API_KEY}
