错误原因是CDB3兼容参数为12.0,而源端cdb1的兼容参数为12.1.0.2
修改：

alter system set compatible='12.1.0.2.0' scope=spfile;

即可。

cdb3的参数文件内容如下：

db_name=cdb3
enable_pluggable_database=true
control_files='/u01/app/oracle/oradata/cdb3/control01.ctl'
db_create_file_dest=/u01/app/oracle/oradata/cdb3/
compatible='12.1.0.2.0'
