select 'REM SID: '||a.sid||' SERIAL#: '||a.serial#||' SQL ID: '||b.sql_id||chr(10)||' /*+ '||sql_fulltext||' */' from v\$session a, v\$sql b where b.address = a.sql_add
ress and program = 'siebmtshmw.exe' and command = 3 and status = 'ACTIVE' and last_call_et >= 300 and username = 'SADMIN';

select 'alter system kill session '||''''||sid||','||serial#||''''||';' from v\$session where program = 'siebmtshmw.exe' and command = 3 and status = 'ACTIVE' and last_c
