Oracle 12c 基于PDB种子数据库创建PDB

CREATE PLUGGABLE DATABASE
  { { pdb_name [ AS APPLICATION CONTAINER ] } | { AS SEED } }
  { create_pdb_from_seed | create_pdb_clone | create_pdb_from_xml } ;

CREATE PLUGGABLE DATABASE PDB_NAME
ADMIN USER PDBA IDENTIFIED BY PASS ROLES=(CONNECT)
FILE_NAME_CONVERT=('/path/pdbseed','/path/pdb_name');

说明：
FILE_NAME_CONVERT:主要用于种子数据库文件与目标数据库文件位置转换
如上示例，FILE_NAME_CONVERT=('/path/pdbseed','/path/pdb_name') 表示新创建的PDB数据库数据文件位于/path/pdb_name
对于以下两种情形，可以不需要FILE_NAME_CONVERT子句
1、启用OMF功能(参数DB_CREATE_FILE_DEST)
    DB_CREATE_FILE_DEST='/u01/app/oradata/cdb1/pdb1'
2、设定初始化参数PDB_FILE_NAME_CONVERT
  PDB_FILE_NAME_CONVERT='/u01/app/oradata/cdb1/seed','/u01/app/oradata/cdb1/pdb'

对于不需要FILE_NAME_CONVERT子句，使用如下方式创建：
CREATE PLUGGABLE DATABASE PDB_NAME
ADMIN USER PDBA IDENTIFIED BY PASS ROLES=(CONNECT);
