不同CDB之间迁移PDB
测试环境
| 源环境 | 目标环境 |
主机操作系统 Oracle Linux 7.2 主机名zhankys Oracle版本 11.2.0.1 x64 IP：172.16.171.214 CDB=orcl 被克隆的PDB=orcl1 | 主机操作系统 Oracle Linux 7.2 主机名zhanky2 Oracle版本 11.2.0.1 x64 IP：172.16.171.215 CDB=cs 克隆后的PDB=cs2 |
测试思路
1、源端建立CP拥有create pluggable database和create session的权限（在PDB orcle1下创建用户）
2、将源端设置为只读模式（CDB模式下设置）
3、在目标端添加orcl1的tnsnames（在tnsnames.ora中添加）
4、在目标端创建orcle1的dblink：cp_link （在CDB模式下运行）
5、在目标端指定db_create_file_dest路径（在CDB模式下运行，如果目录不存在需事先创建）
6、执行克隆PDB语句（在CDB模式下运行）
7、检查数据是否正确(在PDB模式下运行)
