select a.value || b.symbol || c.instance_name || '_ora_' || d.spid || '.trc'trace_file
from (select value from v$parameter where name ='user_dump_dest') a,
(select substr(value, -6, 1) symbol from v$parameter where name = 'user_dump_dest') b,
(select instance_name from v$instance) c,
(select spid from v$session s, v$process p, v$mystat m
 where s.paddr = p.addr and s.sid = m.sid and m.statistic# = 0) d;
