Mälarenergi Improves IT Environment with Proper Licensing That Supports Virtualization


We had a very positive experience with Oracle License Management Services. We ensured that our Oracle Database estate is fully and properly licensed, supports increased virtualization, and thus improves system reliability. It's nice to have a supplier that makes an effort to assure that we are optimizing our investment.

Mälarenergi AB is a city-owned electric power and heating provider based in Västerås, Sweden. Its 160,000 customers include households, businesses, and public institutions in Västmanland County, as well as residential and corporate customers across Sweden.

The company has a large Oracle Database estate. Twelve of its business-critical IT environments run on Oracle Database, including its enterprise resource planning system.

The company's IT department worked with Oracle License Management Services to review Oracle Database license status. An investigation showed that the company was underlicensed. Mälarenergi often purchased single Oracle Database licenses from system vendors that did not always have sufficient knowledge of Oracle's licensing rules.

Oracle License Management Services team helped the company to determine the correct number and type of licenses for its environment.

Previously, every database ran on a physical server, and the company bought a license for each server. Now, Mälarenergi has licenses to run its databases in a virtual cluster. This means it can move more applications into the cluster without new Oracle Database licenses, something that would be needed in a physical environment. The virtualized approach delivers two important benefits: better performance and increased operational reliability. Therefore the new license situation has enabled a much more manageable IT environment.


With Oracle Database and the help of Oracle License Management Services, we have a strong solution in a virtualized environment. Our preference, moving forward, is to choose Oracle over alternative solutions.
