Oracle Release Numer
Oracle 的开发和管理工作中经常会涉及到版本问题,比如数据库升级,附加组件的安装等。通常用 Oracle9i 或 Oracle 10.2g 这种称谓方式来说明当前使用的版本。大致表明当前所使用的数据库版本是可以的,但对于诸如升级操作就需要更详细的版本信息了。
Oracle 官方文档称其为 Oracle Release Number,下面详细解释一下版本号中各个数字的含义。
Major Database Release Number
代表数据库的主版本号,每次数据库大的变更都会反应在这个标识符上,比如 9 –> 10 的变化反映了 Oracle 数据库从网络到网格的一次革新。
Database Maintenance Release Number
数据库每次大的维护,包括一些新功能的引入都会更改。比如 10.1 –> 10.2 管理工具上 Web 管理工具就有些功能上的差别。
Application Server Release Number
这个数字反映了 Oracle Application Server (OracleAS) 的发行版本号。
Component-Specific Release Number
组件的每次更新版本都会反映在第四个数字上。例如,组件的补丁包集合(Patch Sets) 或中间发布版(Interim Releases)
