select distinct b.sid,b.serial# ,b.status,b.program,b.username,b.action,b.module,
to_char( b.logon_time, ‘dd-MON-yyyy hh24:mi:ss’ ) logon_time,

trunc( mod( (sysdate-b.logon_time)*24*60*60, 60 ) ) “Sec”
from gV$access a,gv$session b, gv$process c
where a.sid=b.sid
and b.paddr=c.addr
and b.status=’INACTIVE’
and (b.action like ‘%FRM%’ or b.action like ‘%frm%’ or b.program like ‘%TOAD%’ or b.program like ‘%toad%’ or b.program like

or b.program like ‘%frm%’ or b.action like ‘SQL%’ or b.action like ‘sql%’ or b.action like ‘TOAD%’ or b.action like ‘toad%’)
and (trunc( mod( (sysdate-b.logon_time)*24,24)) >=12 or trunc( sysdate-b.logon_time )>=1);
