We are an Oracle reseller and I have worked with different customers using this solution. This review is largely based on one of my customer's experience with the solution.
This solution allows customers to be able to monitor and manage the complete Oracle IT infrastructure in a single console. Many customers want to consolidate their infrastructure; they gain more in support services, performance, and security because the more you have consolidated, the better the service delivery, and the better the return on investment. The customers who have benefited most are fully consolidated using Oracle storage, Oracle hardware, Oracle databases, and Oracle applications.
In the event that there is an increase in workload, there is a single point of support services. When there is a mix of technologies, you have issues with services, and this is the reason that a unified platform is beneficial.
This solution is designed to maintain critical business applications, and sometimes there are a large number of them. Once this solution is configured, it will help administrators centralize their management of the environment.
With version 12c, it allows you to not only administer but provides valuable insight into the physical server. This includes information such as CPU usage, storage, workload, and details about the operating system.
Ultimately, this solution provides for centralization of everything. The administrators are notified of relevant issues, so a local administrator can attend to fix the problem. This means that problem identification and resolution is quite fast.
Prior to having a single point of management, IT services would not necessarily be able to quickly find the problem. For example, it may arise because of the operating system, CPU utilization, or maybe the hardware. You would not necessarily know what has happened within the environment.
