SQL> SELECT a.VALUE|| b.symbol|| c.instance_name|| '_ora_' || d.spid|| '.trc' trace_file
  2   FROM (SELECT VALUE FROM v$parameter WHERE NAME = 'user_dump_dest') a,
  3   (SELECT SUBSTR (VALUE, -6, 1) symbol
  4   FROM v$parameter WHERE NAME = 'user_dump_dest') b,
  5   (SELECT instance_name FROM v$instance) c,
  6   (SELECT spid FROM v$session s, v$process p, v$mystat m
  7   WHERE s.paddr= p.addr AND s.SID = m.SID AND m.statistic# = 0) d
  8  /
