Oracle Database Discussions

HI,

My DB version is 9.2.0.6 , OS is HP UX 11.11 and i am using EBS 11.5.10

i ran the following query to view no. of inactive sessions

SELECT sid,serial#,status,server
FROM v$session
WHERE username = 'APPS'
and status='INACTIVE';

there were around 300 sessions showing inactive status

can i kill those sessions

i ran another query to view sql realted to them

select a.sql_text , b.sid,b.serial#,b.LOGON_TIME,c.CPU_TIME,c.ELAPSED_TIME,c.IS_OBSOLETE
from v$sqltext a , v$session b , v$sqlarea c
where a.HASH_VALUE=b.SQL_HASH_VALUE
and b.SQL_HASH_VALUE=c.HASH_VALUE
and b.sid=14;

but iam unable to view last updated time or the last time the user worked in the session

my main problem is after 350 sessions my DB becomes really slow

and i have to bounce the DB to solve the prob

is there any other way around??
