Question

我想将Bfiles从db1复制到db2。我无法在db2中创建Bfiles。我在db2实例中使用了DBMS_FILE_TRANSFER.get_file过程。

DBMS_FILE_TRANSFER.get_file(
   source_directory_object      => 'db1_dir',
   source_file_name             => 'test.html',
   source_database        =>  'db2_to_db1',
   destination_directory_object => 'db2_dir',
   destination_file_name        => 'test.html');
END;
/

另外，我在db1实例中尝试过DBMS_FILE_TRANSFER.put_file过程。

DBMS_FILE_TRANSFER.put_file(
   source_directory_object      => 'db1_dir',
   source_file_name             => 'test.html',
   destination_directory_object => 'db2_dir',
   destination_file_name        => 'test.html');
   destination_database        =>  'db1_to_db2',
END;
/

但两个函数都发出相同的错误。

ORA-19505: failed to identify file "/rdsdbdata/userdirs/05/test.html"
ORA-27046: file size is not a multiple of logical block size
Additional information: 1
ORA-02063: preceding 3 lines from db1_to_db2/db2_to_db1

*Cause:    call to identify the file returned an error
