Resolved Alert:
Initial Symptoms
Performance was being monitored. We noticed the max sessions limits get hit. As sessions were ending, the server continued to have problems with CPU and memory. This caused the oracle listener to fail 4 times.
Root Cause Analysis
Cause
There were two primary causes of the problems.
1. The version of Student Registration (9.32.1) had a defect with was causing it to not release sessions.
2. The server was not properly configured in the new RHEL 8 version which caused lingering issues.
Resolution
To address the issue with the Student Registration application, Ellucian recommended that we downgrade to the previous version (9.31.1). This resolved the issues with the hanging sessions.
Prevention
The best way to ensure that this does not occur again is to conduct a stress-test for registration prior to the Spring and Fall registration to identify and resolve any issues prior to opening up registration to the students.
