ORA-27046: file size is not a multiple of logical block size
Cause: file size as indicated by stat is not correct, additional information indicates which function encountered the error
Action: verify that the file has not been overwritten or truncated

The dbms_file_transfer.copy_file requires that the file size be a multiple of 512 bytes, because it is intended for a specific purpose, where it expects to be copying data files containing blocks of data. For what you are doing, you should be using utl_file.fcopy. Please see the demonstration below that reproduces your problem with dbms_file_transfer.copy_file, then solves it with utl_file.fcopy.


SYSTEM@orcl_11g> HOST DEL newvalid.key

SYSTEM@orcl_11g> CREATE OR REPLACE DIRECTORY key_dir AS 'c:\oracle11g'
  2  /

Directory created.

SYSTEM@orcl_11g> GRANT READ ON DIRECTORY key_dir TO scott

Grant succeeded.

SYSTEM@orcl_11g> CREATE OR REPLACE DIRECTORY daywork_dir AS 'c:\oracle11g'
