1.    12c PDB新特点的优势 1)    可以把多个PDB集成进一个平台. 2)    可以快速提供一个新的PDB或一个已有PDB的克隆. 3)    通过拔插技术,可以快速把存在的数据库重新部署到一个新平台上. 4)    多个PDB数据库补丁或升级一次完成. 5)    通过把单个PDB拔插到较高版本的不同CDB,可以补丁或升级一个PDB. 6)    从同一个CDB中众多PDB中分离出某个PDB的内容. 7)    分离这些PDB应用管理员的责任. 2.    12c PDB新特

在Oracle Database 12c中,可组装式数据库 - Pluggable Database为云计算而生.在12c以前,Oracle数据库是通过Schema来进行用户模式隔离的,现在,可组装式数据库可以让此前意义上的多个数据库一起共存. Pluggable Database 其体系结构的核心是:由一个容器数据库(CDB)和多个可组装式数据库(PDB)构成,PDB包含独立的系统表空间和SYSAUX表空间等,但是所有PDB共享CDB的控制文件.日志文件和UNDO表空间.各个PDB之间互访需要
