User session doesn't disconnected

Question

Dear Friends ,
I got a problem in my production server (oracle-10.2.0.1.0) in unix (AIX - 5.3) server where I kill the user's session but it is not disconnected from the database .
Here the output :
SQL> select username,sid,serial#,status from v$session where username='ABABILFE' an
USERNAME SID SERIAL# STATUS
ABABILFE 132 10932 KILLED
ABABILFE 193 13229 KILLED
ABABILFE 222 8246 KILLED
ABABILFE 235 10847 KILLED
ABABILFE 327 15618 KILLED
ABABILFE 346 11205 KILLED
ABABILFE 347 22059 KILLED
ABABILFE 367 11146 KILLED
ABABILFE 379 8560 KILLED
9 rows selected.
I also have to use the following two commands but still sessions are not disconneted .
ALTER SYSTEM DISCONNECT SESSION '132,10932' IMMEDIATE;
ALTER SYSTEM KILL SESSION '132,10932' IMMEDIATE;
And
From v$transaction I got a running transation which is held up from last 18 hours .
SQL> select * from v$transaction;
ADDR XIDUSN XIDSLOT XIDSQN UBAFIL UBABLK UBASQN UBAREC STATUS START_TIME ST
0700000488F170D8 9 44 87983 0 0 0 0 ACTIVE 02/24/09 17:52:40
I cannot remove it .
Here I also mention that , our ABABILFE is our application server's user . when a client is accessing my database then it holds only 'ABABILFE' name so I cannot trace out the user session from the client end as I am working in a Bank . And for this problem , my cpu resource shows always high and performance of my database decreases .
Help me to give me a suggestion plz ASAP ... ...

Thx friends ,
for your kind replies . I also try to kill the process in the o/s level but the process are not still removed . I use the following query which find the running process which are related with our application server :
SQL> SELECT s.sid,p.spid,s.osuser, s.program FROM v$process p,v$session s WHERE p.addr = s.paddr
2 and s.PROGRAM like 'f9%';
SID SPID OSUSER PROGRAM
139 1449994 oracle [email protected] (TNS V1-V3)
213 1835126 oracle [email protected] (TNS V1-V3)
359 2039926 oracle [email protected] (TNS V1-V3)
204 2289670 oracle [email protected] (TNS V1-V3)
Here I kill the '1449994' and '1835126' process using "kill -9" command . It removes from the o/s level but does not remove the database level when I use the above query again .
If there any solution regarding this ?
