DBV-00600: Fatal Error - [21] [2] [0] [0]

I have searched metalink for 10.2.0.5  nothing turned  up there is a solution for the same Bug if it appears in 11.1.0.6  - [ID 731546.1]

But I have found the below solution for 10.2.0.5 and it worked.

Solution: 
Provide the full path of  the file even though you are in the same location doesnt matter  you mention the blocksize or not but good to mention

NODE:TEST:/ora/admin/testrestore>dbv file=/ora/admin/testrestore/TEST_get_file_test.f blocksize=8192
