从种子PDB来创建
第一步，查看pdb状态，如下：
[oracle@dbserver ~]$ sqlplus / as sysdbaSQL*Plus: Release 19.0.0.0.0 - Production on Wed Apr 19 10:10:28 2023

---------- ------------------------------ ---------- ----------2 PDB$SEED READ ONLY NO3 ORCLPDB READ WRITE NO

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：
SQL> set line 1000
SQL> col name format a100
SQL> select name, con_id from v$datafile order by con_id;NAME CON_ID

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');Pluggable database created.SQL> show pdbs;CON_ID CON_NAME OPEN MODE RESTRICTED

第五步，打开上面创建的pdb，如下：
SQL> alter session set container = capturepdb;Session altered.SQL> alter pluggable database capturepdb open;Pluggable database altered.SQL>
SQL> show pdbs;CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------4 CAPTUREPDB READ WRITE NO

此时再新建一个会话，如下：
SQL> show pdbs;CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------2 PDB$SEED READ ONLY NO3 ORCLPDB READ WRITE NO4 CAPTUREPDB READ WRITE NO
SQL> col file_name for a100;

---------- ---------------------------------------------------------------------------------------------------- --------------------23 /home/oracle/oracle19c/oradata/ORCL/capturepdb/undotbs01.dbf UNDOTBS112 rows selected.SQL>
第六步，配置tnsnames.ora，并建立连接，如下：
[oracle@dbserver ~]$ vim ./oracle19c/product/19c/dbhome_1/network/admin/tnsnames.ora
[oracle@dbserver ~]$
[oracle@dbserver ~]$ cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4 oracle
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6 oracle
[oracle@dbserver ~]$
[oracle@dbserver ~]$ cat ./oracle19c/product/19c/dbhome_1/network/admin/tnsnames.ora

[oracle@dbserver ~]$ cat /home/oracle/oracle19c/product/19c/dbhome_1/network/admin/listener.ora

SID_LIST_LISTENER =
(SID_LIST = (SID_DESC = (GLOBAL_DBNAME = orcl)(SID_NAME = orcl))
)
[oracle@dbserver ~]$
然后重启了一下监听，如下：
[oracle@dbserver ~]$ lsnrctl stop ; lsnrctl start
...
[oracle@dbserver ~]$ lsnrctl status
...
[oracle@dbserver ~]$ sqlplus sys/123456@capturepdb as sysdbaSQL*Plus: Release 19.0.0.0.0 - Production on Wed Apr 19 11:20:01 2023

第七步，创建并指定默认表空间，如下：
SQL> col file_name for a100;
SQL> col tablespace_name for a20;
SQL>
SQL> select file_name, tablespace_name from cdb_data_files;FILE_NAME TABLESPACE_NAME
---------------------------------------------------------------------------------------------------- --------------------

/home/oracle/oracle19c/oradata/ORCL/capturepdb/user.dbf USERSSQL>
从本地PDB来克隆
从容器数据库中克隆本地capturepdb来创建replaypdb，如下：
第一步，以只读方式打开capturepdb，如下：
[oracle@dbserver ~]$ sqlplus / as sysdbaSQL*Plus: Release 19.0.0.0.0 - Production on Wed Apr 19 11:33:47 2023

第二步，查看数据文件，并创建新的PDB目录，如下：
SQL> set line 1000;
SQL> col name format a100;
SQL>
SQL> select name, con_id from v$datafile where con_id = 4;NAME CON_ID
---------------------------------------------------------------------------------------------------- ----------

[oracle@dbserver ~]$ cd /home/oracle/oracle19c/oradata/ORCL/
[oracle@dbserver ORCL]$
[oracle@dbserver ORCL]$ ls replaypdb/
[oracle@dbserver ORCL]$
第三步，克隆 如下：
[oracle@dbserver ~]$ sqlplus / as sysdbaSQL*Plus: Release 19.0.0.0.0 - Production on Wed Apr 19 12:44:54 2023
