Is it possible to do a datapump import with a different user than did the export?
It looks like Oracle can't read the .dmp file, because it's under another user's home directory. Oracle has to be able to read it, not the Linux user you're running the impdp command as. (Contrary to my earlier misleading comments!)

Assuming the two users are in different groups, you may need to make the .dmp file world-readable:

chmod o+r /home/..../tmsmv-20120706.dmp


And usually all directories in the path need to be world-readable and world-executable:

chmod o+rx /home/..../


If you wanted the log file to be created, it would be need to be writable too (chmod o+rwx). If it's in a subdirectory of your home directory, you might need to do this to all intermediate levels.

But relaxing permissions on your home directory can be a problem, so you might be better off using a directory somewhere else. Or leave the file where expdp put it, and grant permissions on that DIRECTORY object to tmsmv instead.
