Problem with update

Hi there ...

I have a few (couple hundrets) lines like this in a textfile:

update ams.hardware set kostenstl = '11016' where kostenstl = '11006';

and as last line I have a

commit;

when I connect to the Oracle 8i Server and do the following in sqlplus:

@{path_to_file}\updt.sql

it hangs ... if I do a
set echo on
I see, that it always hangs on the same update statement.

Am I missing something here? Some kind of buffer which is not big enough?
