ORA
-65016: FILE_NAME_CONVERT must be specified

$ oerr ora
65016
65016, 00000, "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 1;
