版本12.2.0.1.0数据库，复制种子数据库快速创建租户数据库PDB
实验测试：快速创建一个数据库PDB2；
实验环境：12.2.0.1.0版本数据库，dbca图形化安装，现有环境，CDB容器数据库ORCL，PDB可插拔数据库ABC
---查询CDB名称，状态
SQL> select name, decode(cdb, 'YES', 'Multitenant Option enabled', 'Regular 12c Database: ') "Multitenant Option" , open_mode, con_id from v$database;

ORCL Multitenant Option enabled READ WRITE 0
SQL> show pdbs --查询PDB名称 ---只有CDB用户，可以查询当前容器下所有其他PDB名称状态，否则只能看自己的

3 ABC READ WRITE NO
SQL> conn / as sysdba --默认此方式连接CDB
