Adobe Flash Plug-in End-of-Life and Enterprise Manager

Many database performance screens in Enterprise Manager were implemented using Adobe Flash technology in versions prior to Enterprise Manager 13.3.2.0.   These database performance pages include ‘Performance Home’, ‘Top Activity’, ‘ASH Analytics’, ‘Real-time SQL Monitoring’ among others.

These Flash pages were replaced with the Oracle JET UI in Enterprise Manager 13.3.2.0 (EM 13.3 PG), released in 2019, and were later enhanced in Enterprise Manager 13.4.

Adobe Flash is being de-supported by Adobe on December 31, 2020.   If you are running versions of Enterprise Manager 13.3.1 or older and use the database performance pages with Adobe Flash goto solution.
