Solution 2373740.1 : Diameter Signaling Router (DSR): How To Clear "ERROR 500 Internal Server Error" When Attempting To Access PM&C GUI Following Software Upgrade Backout

Applies to:

Oracle Communications Diameter Signaling Router (DSR) - Version DSR 7.0 and later
Tekelec

Goal

After backout of Platform Management and Configuration (PM&C) server to a previous release, web browser graphical user interface (GUI) may not connect and provide the message "ERROR 500: Internal Server Error."

Solution

If the user had accessed the PM&C server GUI via the same browser before backing to a previous release, the local browser cache will contain mismatched data / client-side code. Clearing the browser cache will force the browser to solicit and use client-side code at the right release level to interface with the web server (PM&C) GUI.

This step is documented in the PM&C Incremental Upgrade Guides [ https://docs.oracle.com/en/industries/communications/tekelec-platform/index.html - Tekelec Platform Management and Configuration section ] for each release.
