In a typical company, when the response times of your applications are not within acceptable levels, problem resolution can be very 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 very 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 needed 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 helps manage the resources that are shared by applications in a cluster. 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, but instead works to remove obstacles that prevent your applications from running at their optimal performance levels.
