X racle 18c创建PDB的几种方式（2）--利用seed模板创建PDB

利用模板创建pdb


1、

利用语句查询出cdb与pdb的数据文件对应关系：
SQL> 1
  1* select NAME from v$datafile
SQL> 


NAME
--------------------------------------------------
/u01/app/oracle/oradata/PROD/system01.dbf
/u01/app/oracle/oradata/PROD/sysaux01.dbf
/u01/app/oracle/oradata/PROD/undotbs01.dbf
/u01/app/oracle/oradata/PROD/pdbseed/system01.dbf
/u01/app/oracle/oradata/PROD/pdbseed/sysaux01.dbf
/u01/app/oracle/oradata/PROD/users01.dbf
/u01/app/oracle/oradata/PROD/pdbseed/undotbs01.dbf
/u01/app/oracle/oradata/PROD/pdb3/system01.dbf
/u01/app/oracle/oradata/PROD/pdb3/sysaux01.dbf
/u01/app/oracle/oradata/PROD/pdb3/undotbs01.dbf
/u01/app/oracle/oradata/PROD/pdb3/users01.dbf
/u01/app/oracle/oradata/PROD/pdb/system01.dbf
/u01/app/oracle/oradata/PROD/pdb/sysaux01.dbf
/u01/app/oracle/oradata/PROD/pdb/undotbs01.dbf
/u01/app/oracle/oradata/PROD/pdb/users01.dbf
/u01/app/oracle/oradata/PROD/pdb2/system01.dbf
/u01/app/oracle/oradata/PROD/pdb2/sysaux01.dbf
/u01/app/oracle/oradata/PROD/pdb2/undotbs01.dbf
/u01/app/oracle/oradata/PROD/pdb2/users01.dbf

然后根据上面的路径设置新的pdb的路径对应关系 等：

CREATE PLUGGABLE DATABASE cndbapdb   
  ADMIN USER cndbaadm IDENTIFIED BY testpwd  
    ROLES=(DBA)  
  STORAGE (MAXSIZE 2G)  
  DEFAULT TABLESPACE cndba  
    DATAFILE '/u01/app/oracle/oradata/PROD/cndbapdb/cndba01.dbf' SIZE 100M AUTOEXTEND ON  
  PATH_PREFIX = '/u01/app/oracle/oradata/PROD/'  
 FILE_NAME_CONVERT = ('/u01/app/oracle/oradata/PROD/pdbseed','/u01/app/oracle/oradata/PROD/cndbapdb'); 
 
上面是创建了一个名为cndbapdb的PDB，创建一个cndbaadm管理用户并赋PDB_DBA权限，限制PDB可以使用空间大小为2G，创建表空间为cndba并设置为默认表空间。
