The Emergency Monitoring feature of Enterprise Manager Cloud Control 12c is an evolution of Memory Access Mode from Grid Control 11g, allowing you to access in-memory statistics. In EM12c you no longer need to explicitly enable memory access mode. Just navigate to the page and wait while it makes a diagnostic connection to the database and performs lightweight analysis. The screen contains information that will help analyze performance issues, even if the database is hung and you can't connect to the normal performance pages.
