番外：克隆本地PDB中其他参数和子句的说明

基于版本：19c （12.2.0.3） AskScuti

创建方法：克隆本地PDB（从本地其他PDB创建新的PDB）

对应路径：Creating a PDB --> Cloning --> Locally

具体请参考《在多租户（容器）数据库中如何创建PDB：方法2》

1. 内容总览

2. 设置 PDB_FILE_NAME_CONVERT

3. 使用 FILE_NAME_CONVERT 本地克隆

4. 使用 CREATE_FILE_DEST 本地克隆

1. 内容总览

接--克隆本地PDB一文中的其他参数设置。

2. 设置 PDB_FILE_NAME_CONVERT

SQL> !mkdir /u01/app/oracle/oradata/CDB1/pdb3

SQL> show parameter pdb_file

SQL> alter system set pdb_file_name_convert='/u01/app/oracle/oradata/CDB1/pdb1','/u01/app/oracle/oradata/CDB1/pdb3';

System altered.

创建PDB3

SQL> alter pluggable database pdb1 close;

Pluggable database altered.

SQL> alter pluggable database pdb1 open read only;

Pluggable database altered.

SQL> create pluggable database pdb3 from pdb1;

Pluggable database created.

SQL> show pdbs

    CON_ID CON_NAME  OPEN MODE  RESTRICTED
---------- --------- ---------- ----------
     2 PDB$SEED      READ ONLY  NO
     3 PDB1          READ ONLY  NO
     4 PDB2          READ WRITE NO
     5 PDB3          MOUNTED

开启PDB3

SQL> alter pluggable database pdb3 open;

Pluggable database altered.

3. 使用 FILE_NAME_CONVERT 本地克隆

使用 FILE_NAME_CONVERT 子句创建

SQL> !mkdir /u01/app/oracle/oradata/CDB1/pdb4

SQL> create pluggable database pdb4 from pdb1 file_name_convert=('/u01/app/oracle/oradata/CDB1/pdb1','/u01/app/oracle/oradata/CDB1/pdb4');

Pluggable database created.

注意：被克隆的PDB1要处于只读状态。

SQL> alter pluggable database pdb4 open;

Pluggable database altered.

SQL> show pdbs

    CON_ID CON_NAME  OPEN MODE  RESTRICTED
---------- --------- ---------- ----------
     2 PDB$SEED      READ ONLY  NO
     3 PDB1          READ ONLY  NO
     4 PDB2          READ WRITE NO
     5 PDB3          READ WRITE NO
     6 PDB4          READ WRITE NO

4. 使用 CREATE_FILE_DEST 本地克隆

使用 CREATE_FILE_DEST 子句创建

SQL> !mkdir /u01/app/oracle/oradata/CDB1/pdb5

SQL> create pluggable database pdb5 from pdb1 create_file_dest='/u01/app/oracle/oradata/CDB1/pdb5';

Pluggable database created.

注意：被克隆的PDB1要处于只读状态。

SQL> alter pluggable database pdb5 open;

Pluggable database altered.

SQL> show pdbs

    CON_ID CON_NAME  OPEN MODE  RESTRICTED
---------- --------- ---------- ----------
     2 PDB$SEED      READ ONLY  NO
     3 PDB1          READ ONLY  NO
     4 PDB2          READ WRITE NO
     5 PDB3          READ WRITE NO
     6 PDB4          READ WRITE NO
     7 PDB5          READ WRITE NO
