Multitenant Unplug/Plug Best Practices (文档 ID 1935365.1) 1.source 从0419 升级到1019 ,但是datapatch 没有回退0419,导致plug pdb 在target 1019后,数据库无法正常open. 2. 操作步骤如下:(检查cdb 和plug pdb 兼容性,发现一旦不兼容,plug pdb 只能以受限制模式打开,无法使用,解决办法无.怀疑是步骤3 的bug) source create pluggable dat…

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…

什么是Data Redaction Data Redaction是Oracle Database 12c的高级安全选项之中的一个新功能,Oracle中国在介绍这个功能的时候,翻译为“数据编纂”,在EM12c R3的中文界面中,这个功能被翻译成“数据编写”,我认为后一个翻译更贴切. 在12c发布前,某次以“数据库安全”为题目的技术交流中,有一个客户问我们,Oracle数据库里面能不能实现这么一个功能:符合条件的用户可以看到表里面的所有数据,而另外一些人(业务权限低的用户)虽然能查询表,但是某些敏感…
