Over time, Oracle Database has improved and simplified product installation process and its options. Nowadays, most wizards allow to install and create most of the databases in a trivial way. However, installing and configuring an Oracle database has a high impact on the quality of the later phases of the life cycle of projects. Verifying environment certification to be assured of support, the adjustment of operating system configuration, storage and networks, an appropriate use of the physical structure and a standard nomenclature definition, the configuration and parameterization of databases instances are factors to consider for a right installation, which should be part of the architecture of the project and executed with maximum precision to establish the foundations for a stable and secure environment.
Oracle Database Support Cycle triggers the need for periodic product updates to have a supported database environment. Other times, Migration projects are triggered by changes in the hardware platform or by the Applications Support cycle. In all cases, a Migration requires Expert Services to reduce the risks associated to the change. In critical environments, there is no downtime or it is minimal and changes in application behavior resulting from a change of version are fundamental, it can seriously affect the service if it hasn’t done a set of tests of version change impact . Nucli in addition to his experience of more than one hundred projects of this type provides a set of Best Practices to minimize the risk of change and service downtime resulting from these actions.
The approach of these projects goes through a careful taking of requirements and knowledge of the global environment, a extensive definition of the change process, environment testing with clear definition of the adjustments to be made and, when necessary, the use of technology to move data when there is no standstill window
