| Application Server Release Number | The third digit reflects the release level of the Oracle Application Server (OracleAS). |
| Component-Specific Release Number | The fourth digit 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. |
