oracle怎么改成升 oracle怎么修改

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，

如何将 oracle 10g 升级到 orcale 12c

可以直接升级到12C的数据库版本有：

•Oracle数据库10g(10.2.0.5)

•Oracle 数据库 11g (11.1.0.7)

•Oracle 数据库 11g (11.2.0.2 或后续版本)

如果数据库版本非以上三种，比如是10.2.0.1.0想要升级到12C，需要先将数据库升级到10.2.0.5或其他直接版本，才能再次升级到12C。

如何将 Oracle 11g 升级到 Orcale 12c

一般生产系统不会进行这种大版本的升级操作。一般都是将数据expdp导出，然后再导入到要升级到的版本中。这种数据库需要应用去配合更改应用。
