Oracle Coherence vs Oracle Enterprise Manager comparison

Oracle Coherence is an in-memory data grid solution that enables organizations to predictably scale mission-critical applications by providing fast access to frequently used data. As data volumes and customer expectations increase, driven by the “internet of things”, social, mobile, cloud and always-connected devices, so does the need to handle more data in real-time, offload over-burdened shared data services and provide availability guarantees.

Oracle Coherence comes with a rich set of processing and event capabilities so applications can scale processing with increased data volumes. By automatically and dynamically partitioning data, Oracle Coherence ensures continuous data availability and transactional integrity, even in the event of a server or site failure.

Oracle Coherence provides organizations with a robust scale-out data abstraction layer that brokers the supply and demand of data between applications and data sources. This cost-effectively offloads shared data services such as databases, mainframes, and partner services.

Reviews from Real Users

Oracle Enterprise Manager stands out among its competitors for a number of reasons. Several major ones are its central management and monitoring and its reporting capabilities

Robin C., head of Oracle Exadata Centre of Excellence at Tata Consultancy Services, writes, "The database performance monitoring features are very useful and allow us to quickly zero in on DB-related issues. Exadata storage server and Infiniband switches can be viewed from the GUI in OEM which cannot be done in other tools. The ability to deploy metric extensions makes this tool extensible for our custom monitoring also."

PeerSpot users note the effectiveness of these features. A database manager at a tech services company notes, “The solution's most valuable aspect is the fact that it is embedded with the Oracle database and Oracle's engineering system, its extra data, and analytics.  They have plug-ins that are very helpful. Due to the infrastructure's size, the introduction they offer is very, very useful. It helps with an overall understanding of the product. They have a very nice graphical user interface. The monitoring is good. We can capture the SQL tune from us. With Oracle Enterprise Managers, we can see the rich performance tuning.”
