从种子PDB来创建
第一步，查看pdb状态，如下：
[oracle@dbserver ~]$ sqlplus / as sysdba

如上，seed pdb 在数据库cdb启动时处于read only的状态！
第二步，查看其数据文件，如下：

第三步，创建新的PDB目录，如下：
-- mkdir capturepdb
-- mkdir replaypdb
[oracle@dbserver ~]$ cd /home/oracle/oracle19c/oradata/ORCL/
[oracle@dbserver ORCL]$ ls
capturepdb control01.ctl control02.ctl orclpdb pdbseed redo01.log redo02.log redo03.log replaypdb sysaux01.dbf system01.dbf temp01.dbf undotbs01.dbf users01.dbf
[oracle@dbserver ORCL]$
[oracle@dbserver ORCL]$ ls capturepdb/
[oracle@dbserver ORCL]$
[oracle@dbserver ORCL]$ ls replaypdb/
[oracle@dbserver ORCL]$
第四步，创建capturepdb，如下：
SQL> create pluggable database capturepdb admin user sysdba identified by 123456 roles=(connect) file_name_convert=('/home/oracle/oracle19c/oradata/ORCL/pdbseed','/home/oracle/oracle19c/oradata/ORCL/capturepdb');
