• Introduction to Oracle Cluster Health Advisor
  Oracle Cluster Health Advisor continuously monitors cluster nodes and Oracle RAC databases for performance and availability issue precursors to provide early warning of problems before they become critical.
• Introduction to Memory Guard
  Memory Guard is an Oracle Real Application Clusters (Oracle RAC) environment feature to monitor the cluster nodes to prevent node stress caused by the lack of memory.
• Introduction to Hang Manager
  Hang Manager is an Oracle Real Application Clusters (Oracle RAC) environment feature that autonomously resolves hangs and keeps the resources available.
• Introduction to Oracle Database Quality of Service (QoS) Management
  Oracle Database Quality of Service (QoS) Management manages the resources that are shared across applications.
