Meet the Oracle Licensing ExpertsMany end users make use of a disaster recovery (DR) solution in which data is copied from the primary production database to the secondary disaster recovery database. Often, end users either make use of the functionalities of Data Guard or Active Data Guard to achieve such a solution. But how does licensing Data Guard and Active Data Guard work? And does the installation of the Data Guard Observer on a license require you to license the Oracle Database? This since Oracle states in its license agreements that the software is required to be licensed, once the software is “installed and/or running”. In order to answer these questions, we should first have a clear view of the differences between Data Guard and Active Data Guard.
The Data Guard feature provides a comprehensive set of services that create, maintain, manage, and monitor one or more standby databases to enable production Oracle databases to survive disasters and data corruptions. Data Guard maintains these standby databases as transactionally consistent copies of the production database. Data Guard is a feature of the Oracle Database Enterprise Edition itself and does not require separate licensing.
On the other hand, Active Data Guard is a so-called Oracle Database Enterprise Edition Option and as such requires separate licensing. Active Data Guard was introduced with Oracle Database 11g Release 1 to provide important extensions to basic Data Guard functionality that further enhance data protection, availability, and return on investment (ROI) in standby systems. To be concrete both the primary production server and the secondary DR server are required to be fully licensed and the same license metric should be applied as to the associated licenses for the Oracle Database itself.
Active Data Guard includes a number of features and functionalities, such us:
Active Data Guard is an evolution of Data Guard technology that improves production database performance for critical transactions. As such, both Active Data Guard and Data Guard are related technologies, but their use results in different licensing requirements.
As per Oracle’s program documentation, the Client software (to connect with the Oracle Database) can be installed separately on the specific end user device that connects to the Oracle Database. The installation of the Oracle Client itself as such does not require separate licensing, as long as the Oracle Database itself as installed on a server is licensed with sufficient Named User Plus and/or Processor licenses.
