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;

NAME      Multitenant Option         OPEN_MODE                CON_ID

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

2 PDB$SEED                 READ ONLY  NO

3 ABC                            READ WRITE NO

SQL> conn / as sysdba       --默认此方式连接CDB

Connected.

 

SQL> select con_id,file_name from cdb_data_files;    --CDB容器数据库，拥有所有权限，可以管理PDB租户数据库，应该还有种子数据库的数据文件，但是不可见
