Changing DPA's default HTTPS port from 8124 to 443 in Database Performance Analyzer (DPA)

Database Performance Analyzer (DPA) uses port 8124 for HTTPS by default. Whether DPA can be configured to use port 443 instead depends on the operating system hosting the DPA application.

Overview

The default HTTPS port for Database Performance Analyzer (DPA) is 8124, configured via the Apache Tomcat server.xml file located at DPA-install-dir\iwc\tomcat\conf\server.xml. Customers may want to change this to port 443, the standard HTTPS port, to avoid specifying a non-standard port in browser URLs.

Resolution

The feasibility depends on whether DPA is hosted in a Linux or Windows environment.

Port 443 is considered a privileged port in Linux environments, and a user running DPA without elevated permissions may not be able to bind to it.

In Linux/Unix systems, any port below 1024 (including port 443) is considered a privileged port. This means that only processes running with root privileges can bind to these ports.

Therefore, if you intend to use port 443 when running DPA as a non-root user, configuring it directly in the server.xml file is not supported.

For Windows environments, the situation is different. Windows does not enforce the same privileged port restrictions. A user running DPA on Windows can modify the server.xml file to use port 443, provided that the port is not already in use by another service, such as IIS.

IMPORTANT: The final point is critical — the port must be unique, and port 443 must not already be in use by another process before proceeding with this change.
