一、删除PDB并删除数据文件

所删除的pdb必须是mount的状态才可以删除：

#1、关闭pdb
alter pluggable database pdb_name close immediate instances=all;
#2、删除pdb以及数据文件
drop pluggable database  pdb_name including datafiles;

二、删除PDB并保留数据文件

#1、默认删除pdb就是保留数据文件
drop pluggable database  pdb_name;
#2、删除pdb并保留数据文件（keep datafiles）
drop pluggable database  pdb_name keep datafiles;

三、插拔PDB

#1、关闭pdb
alter pluggable database pdb_name01 close immediate instances=all;
#2、拔出pdb
alter pluggable database  pdb_name01 unplug into '/home/oracle/pdb_name01.xml';
#3、被拔出的pdb只可删除
drop pluggable database  pdb_name01;
#4、插入pdb
create pluggable database pdb_name02 using '/home/oracle/pdb_name01.xml' nocopy;
#5、打开pdb
alter pluggable database pdb_name02 open instances=all;
#6、查询是否打开pdb报错
select name,cause,type,message,status from pdb_plug_in_violations order by name;
#7、保存状态
alter pluggable database pdb_name02 save state instances=all;
