对于Oracle数据库升级操作，每个版本之间的升级步骤均相似，首先升级Oracle软件，然后升级数据库内的数据字典表。
在Oracle12c中，当我们通过容器的方式对数据库进行整合后，其升级方式变得更加灵活，整合后我可以选择对容器中的所有PDB数据库进行升级，也可以通过克隆/移动以及unplug/plug的方式对其中的某一个PDB数据库进行升级从而不影响容器中的其他PDB数据库。
如下将演示如何通过unplug/plug的方式升级pdb数据库。
原环境为：
目标环境：
这里将12.1版本的容器oradb中pdb1通过unplug/plug方式插入到容器ora12c中，以此方式完成对pdb1数据库的升级。
过程如下：
1.原平台测试数据准备

Session altered.

sys. oradb>create tablespace tbs01 datafile size 200M;

yyh. pdb1>2.卸载Oracle APEX
Oracle APEX在12.1.0.2.0中默认安装，而在12.2.0.1.0未默认安装，如果不进行APEX卸载，在12.2.0.1.0中plug 12.1.0.2.0版本的pdb将报如下ORA-65346错误：
当然，如果您有使用到APEX，需要在12.2.0.1.0中安装APEX，而无需卸载12.1.0.2.0中的APEX。
卸载方式：
