Oracle Version Numbers Something that always comes up when discussing Oracle versions is that I am not always sure which number is the Major Database Release and which is the Database Maintenance Release. In the Oracle documentation, the numbers are clearly described: Oracle Release Number Format 12.1.0.1.0 ┬┬┬┬┬ │ │ │ │ └───── Platform-Specific Release Number │ │ │ └────────── Component-Specific Release Number │ │ └─────────────── Fusion Middleware Release Number │ └──────────────────── Database Maintenance Release Number └───────────────────────── Major Database Release Number Whereas the different numbers mean the following: Major Database Release Number The first numeral is the most general identifier. It represents a major new version of the software that contains significant new functionality. Database Maintenance Release Number The second numeral represents a maintenance release level. Some new features may also be included. Fusion Middleware Release Number The third numeral reflects the release level of Oracle Fusion Middleware. Component-Specific Release Number The fourth numeral identifies a release level specific to a component. Different components can have different numbers in this position depending upon, for example, component patch sets or interim releases. Platform-Specific Release Number The fifth numeral identifies a platform-specific release. Usually this is a patch set. When different platforms require the equivalent patch set, this numeral will be the same across the affected platforms.
