ERROR at line :
ORA-: FILE_NAME_CONVERT must be specified

$ oerr ora
, , "FILE_NAME_CONVERT must be specified"
// *Cause:  Data files, and possibly other files, needed to be copied as a
//          part of creating a pluggable database.  However, Oracle Managed
//          Files (OMF) was not enabled, PDB_FILE_NAME_CONVERT was not defined,
//          and there was a failure to specify the FILE_NAME_CONVERT clause.
// *Action: Enable OMF or define PDB_FILE_NAME_CONVERT system parameter before
//          issuing CREATE PLUGGABLE DATABASE statement, or specify
//          FILE_NAME_CONVERT clause as a part of the statement.

如果未指定db_create_file_dest  参数则需要手动在CREATE PLUGGABLE DATABASE时指定FILE_NAME_CONVERT，例如：

SQL> create pluggable database yb1 admin user yb1 identified by yb1 file_name_convert=('/u12/app/oracle/oradata/ora12/pdbseed/','/u12/app/oracle/oradata/ora12/yb1/');

也可以使用参数db_create_file_dest
SQL> alter system set db_create_file_dest='/u12/app/oracle/oradata';

创建成功后查看
SQL> select con_id,name,open_mode,restricted from v$pdbs order by ;

    CON_ID NAME                           OPEN_MODE  RES
---------- ------------------------------ ---------- ---
          PDB$SEED                       READ ONLY  NO
          YB                             READ WRITE NO
          YB1                            MOUNTED
