Tuning, Troubleshooting and Forecasting


Tuning, Troubleshooting and Forecasting

The system performance is a combination of several layers, such as available hardware, operating system, interconnection system, database and its use on applications. Application Development often focuses on business and functional aspects. Available development tools, usually don't allow to make database operations optimally. As a result of these factors, each application may have its own particular profile which can even change over time depending on data volumes.

The excellence of Oracle technology for consistent information management can be shown with its majority market share. However, this technology doesn’t guarantee by itself the applications performance. Suboptimal performance applications are a common issue, that results in Ownership cost increases (TCO) of technology, user displeasure and direct impact in business results. Based on an application profile, NUCLI applies a methodology that analyzes pending events in Oracle Database (there are over 400 types) and from this diagnosis NUCLI can make recommendations that result in dramatic improvements of performance. These improvements are available transparently to the application by adjusting the Oracle instance and / or modifying the physical data model, in other cases, the recommendations may cover from improving the physical data model to SQL rewriting seeking the best ratio between the effort it would take to the impact in development and performance improvement that you can obtain.
