Background

I recently had opportunity to support team who has been battling with Intermittent (scary i know :)) issues with TCP connectivity in Production.

Simplified deployment Architecture is as below,

Technology Stack used is Microsoft .NET Framework 4.8 using ODP.NET for Oracle Connectivity (Oracle Server is 8 CPU box). Each of Web Servers in cluster have IIS hosted on it with multiple Applications (Application domains) serving HTTP(s) based traffic. These applications connect to Oracle Database.
