如何升级oracle版本

　1. 先检查数据库当前版本：SELECT * FROM v$version;

2. 使用RMAN或exp 进行全库备份

【这一步非常非常重要，因升级到数据部分时，虚拟机没空间了，导致VM崩溃，升级失败.orcl库也挂了，不得不从另一台Oracle上创建了一个Orcl,然后，冷备迁移过来，才得以重新升级。】

怎样单独升级oracle的客户端

简单点就把心版本装好，然后将旧版本卸载即可。主要设置好环境变量即可。

如何升级Oracle Grid Infrastructure和RAC从11.2.0.3到11.2.0.4

为新版本的GI新建一个新home目录，解压升级包 执行安装程序 会自动检测到正在运行的cluster,选升级选项 ，目录选新home ，后面的按提示完成升级 升级好后更改环境变量指向新home

如何实现最快的Oracle EBS 12升级

首先这两个面对的对象就是不同的，EBS面对的是企业业务逻辑。DBA面对的是数据库管理。前者更偏向于与人的交流。 要说有前途的话，个人感觉EBS比较有前途，毕竟与人交流是王道。

如何将 Oracle 11g 升级到 Orcale 12c

下载12c的安装包，如果是linux环境，运行./runinstaller，如果是windows环境，运行setup.exe程序。安装选项选择升级现有的数据库，需要注意的是，保证11g的小版本达到11.2.0.4或以上

12c引入了多租户的概念，即一个实例可有多个数据库。但是通过11g升级上来的数据库依然是一个NON-CDB的数据库。
