In the complex world of database management, ensuring optimal performance and efficient resource utilization is crucial, especially when dealing with powerful systems like Exadata. This blog highlights an upcoming series that will delve into three critical aspects of Exadata manageability. Get ready to explore capacity and configuration monitoring, CPU constraint identification, and efficient IO resource management, all aimed at empowering you to manage your Exadata fleet effectively.
Efficiently Manage and Monitor Exadata Fleets with Exadata Capacity and Configuration Dashboards
Session 1: June 26, 2025 | 9 am PT – Replay available
Even if you have one or several Exadata systems in your environment it is important to know capacity available and used on your Exadata or Exadata VM clusters. One cluster is over-provisioned while another has capacity available. With our newly introduced Exadata Capacity dashboards it is possible to identify high or low utilization on CPU, Memory and Input/Output (I/O).
The Exadata Capacity dashboards introduce a game-changing approach to resource management. By analyzing these dashboards, administrators can quickly identify clusters with over-provisioned or underutilized resources. This visualization enables them to optimize CPU, memory, and I/O allocations, ensuring each Exadata system operates at its peak efficiency.
The dashboard’s ability to provide a holistic view of the Exadata environment empowers DBAs and IT managers to make informed decisions. For instance, identifying an over-provisioned cluster allows for the redistribution of resources to where they are most needed. This not only improves overall system performance but also ensures cost-effectiveness by maximizing the utilization of existing resources.
Identify and Solve CPU Constraints for Databases on an Exadata Using Database Impact Advisor
Session 2: July 8, 2025 | 9 am PT- Replay Available
Several databases in a cluster with over-provisioned CPU_COUNT is a rather normal situation. But this can lead to high CPU utilization. Learn how to identify databases that are exposed or impacted by CPU capacity and how Database Impact Advisor will provide advice for an optimal CPU_COUNT for every database in the cluster to reduce or eliminate databases from impacting each other.
CPU over-provisioning is a common challenge in database clusters. While it might seem advantageous, it often leads to high CPU utilization and potential performance bottlenecks. The session highlights a practical approach to addressing this issue using the Database Impact Advisor. By leveraging this tool, administrators can thoroughly examine databases within a cluster and pinpoint those affected by CPU capacity constraints. The Database Impact Advisor goes beyond identification; it provides actionable advice. It recommends an optimal CPU_COUNT for each database, aiming to minimize the impact of one database’s CPU usage on others. This proactive approach ensures that databases coexist harmoniously within the cluster, reducing the chances of performance degradation.
Efficient Monitoring and Management of IO Resource Management Using the IORM Advisor
Session 3: Aug 21, 2025 | 9 am PT – Register
Input/Output (I/O) resources are shared between all databases among all clusters on same Exadata. As a database administrator on an Exadata you can use AWR to monitor I/O usage, but you cannot see details on IORM settings and how IORM restricts other databases. Learn how IORM Advisor provides you with details on IO usage for every database and if they are impacted by IORM. IORM Advisor will provide details that make it possible to reduce IO resources to less important databases with increased IO resources to more important databases.
IO resources are the lifeblood of any database system, and on Exadata, they are shared among all databases across clusters. While AWR monitoring provides insights into IO usage, it falls short in revealing the impact of IORM settings on individual databases. This is where the IORM Advisor steps in, offering a comprehensive solution.
The IORM Advisor provides an in-depth analysis of IO usage for each database, shedding light on the impact of IORM restrictions. With this tool, administrators can make informed decisions about IO resource allocation. By understanding which databases are IO-constrained, DBAs can adjust settings to reduce resources for less critical databases and boost performance for those with higher priority. This ensures a balanced and efficient IO resource management strategy.
The Observability Insights session presented a wealth of knowledge for Exadata administrators, focusing on the critical aspects of capacity, CPU, and IO management. By utilizing the Exadata Capacity and Configuration Dashboards, Database Impact Advisor, and IORM Advisor, DBAs can transform their Exadata management approach. These tools enable efficient monitoring, proactive issue identification, and optimized resource allocation, ultimately leading to a high-performing and well-managed Exadata environment.
