Many database architecture options are available to you, such as RAC, mirroring, clustering, cloud deployment, and others. Navis connects to the database via a standard JDBC connection mechanism. It is each customer's responsibility to architect database instances in accordance with their needs while ensuring database responsiveness.
The customer is wholly responsible for configuration, testing, tuning, and on-going database environment support and recovery options, regardless of which database is used. It may be necessary to have in-house or contracted expertise for setting up and maintaining the database. If Navis reasonably believes that an issue is unique to your database environment, then Navis may request that you contact your database vendor directly.
