I am currently using an application called Maximo which sits on Windows Terminal Server and I am trying to trace what happens when a user saves a record in the front end.
What is the SQL comand to do this

On your unix side you can try the following two from SQL*Plus:
1.) Run the following query to get the SID
select si.sid,
s.username "User Name",
s.osuser "OS User",
s.status "Status",
lockwait "Lock Wait",
s.program "Program",
s.machine "Machine",
s.logon_time "Connect Time",
p.program "P Program",
s.process "Process",
p.spid, p.pid, s.serial#
from sys.v_$sess_io si, sys.v_$session s, sys.v_$process p
where s.username is not null and
si.sid(+)=s.sid
and p.addr(+)=s.paddr
2.) Run the trace.
