Oracle Database QoS Management helps manage the resources shared by databases and their services in a cluster.
In a typical company, when the response times of your applications are not within acceptable levels, problem resolution can be slow. Often, the first questions that administrators ask are: "Did we configure the system correctly? Is there a parameter change that fixes the problem? Do we need more hardware?" Unfortunately, these questions are difficult to answer precisely. The result is often hours of unproductive and frustrating experimentation.
Oracle Database QoS Management provides the following benefits:
Reduces the time and expertise requirements for system administrators who manage Oracle Real Application Clusters (Oracle RAC) resources
Helps reduce the number of performance outages
Reduces the time required to resolve problems that limit or decrease the performance of your applications
Provides stability to the system as the workloads change
Makes the addition or removal of servers transparent to applications
Reduces the impact on the system caused by server failures
Helps ensure that service-level agreements (SLAs) are met
Enables more effective sharing of hardware resources
Oracle Database QoS Management can help identify and resolve performance bottlenecks. Oracle Database QoS Management does not diagnose or tune application or database performance issues. When tuning the performance of your applications, the goal is to achieve optimal performance. Oracle Database QoS Management does not seek to make your applications run faster. Instead, Oracle Database QoS Management works to remove obstacles that prevent your applications from running at their optimal performance levels.
