Memory Guard Does Not Require Oracle Database QoS Management to be Active
With this release, Memory Guard is enabled by default independent of whether you use Oracle Database Quality of Service Management (Oracle Database QoS Management). Memory Guard detects memory stress on a node and causes new sessions to be directed to other instances until the existing workload drains and frees memory. When free memory increases on the node, then services are enabled again to automatically accept new connections.

The Diagnosability Framework enables Oracle products to use a standardized and simplified way of storing and analyzing diagnosability data.
