To achieve peak performance in your Oracle Real Application Clusters (RAC) environment, where interconnected servers or nodes collaborate to deliver high availability and scalability for critical Oracle databases, employing a robust monitoring tool is imperative. This monitoring tool should track essential performance metrics to ensure smooth and efficient operations. This is where Applications Manager comes into picture!
With Applications Manager's Oracle RAC monitoring tool,
In a RAC setup, there are multiple instances, each operating on a unique node (server) within the cluster. These instances collaborate to administer the shared database, ensuring enhanced availability, scalability, and load balancing. With Applications Manager, track the nodes in which these instances are running, get notified when database size grows beyond a reasonable limit or grows fast. You can also gauge the workload on your instances by tracking the number of user sessions.
Monitor nodes and their OS types. Get to know the interconnect IP they're using to communicate with each other. Configure alarms for CPU and memory utilization metrics to get notified of increasing values to prevent sudden downtime and excessive swapping or paging.
Monitor Disk Group types and states to identify any disk group that might be in a degraded state due to disk failures. Initiate repair actions promptly to prevent disruptions to the database service. Isolate disk groups that are heavily utilized and redistribute data across disks to balance the load and improve performance. You can even anticipate data growth based on 'Used Memory' percentage and execute the necessary expansions or archiving strategies.
Keep an eye on the health and availability of Pluggable databases. Detect and address issues such as PDB startup or shutdown failures, data corruption, or excessive resource utilization.
Applications Manager also lets you set up AI-powered alerts on critical performance metrics to get notified on the go. You can also access trend analysis reports, historical reports, and forecast reports to analyze growth and utilization of resources and plan your future capacities effectively!
