How i can informations about file locking for applications.
if i open a document with one application on the terminalserver and try to
open the same document in another session i can write on the second
session. this happens for example with openoffice. how i can really lock
the file if one application open this doc for reading and writing ?

start with 'man -k lock|grep file' That will give you some
starting points. If you need more any book on UNIX or Linux
programming that doesn't list both methods isn't worth buying.

read Documentation/locks.txt and Documentation/mandatory.txt.
You can also use advisory locking (man 2 fcntl, lockf), if it's
your own code.
