Help needed to tune the Query:Statistics added

Question

Can someone DBA please help me to tune this query:
SELECT DISTINCT K.ATTRIBUTE_VALUE AGENCY_ID,B.PROFILE_NM ,NVL(G.OFFICE_DESC,'--') OFFICE_DESC,f.OFFICE_ID,B.PROFILE_ID,'%' ROLE,'%' LAYOUT,
CASE
WHEN 'flagB' = '%' THEN
NVL(J.ISS_GRP_DESC,'BILLING')
WHEN 'flagO' = '%' THEN
NVL(J.ISS_GRP_DESC,'ORDERING')
WHEN 'flag' = '%' THEN
NVL(J.ISS_GRP_DESC,'BILLING/ORDERING')
ELSE
NVL(J.ISS_GRP_DESC,' ')
END ISS_GRP_DESC,
DECODE(NVL(H.USERID,' ') ,' ','--','<a sbcuid_in=' || H.USERID || ' target=NEW >'||H.FIRSTNAME || ' ' || H.LASTNAME || '( ' || H.USERID || ' )</a>' ) USER_NAME
FROM
PROFILE_PORTAL B ,
TBL_BDA_AGENCY_RESP_REP C ,
TBL_BDA_AGENCY_OFFICE F,
TBL_BDA_OFFICE G,
USERS_PORTAL H,
TBL_BDA_USR_ISS_GRP I ,
TBL_BDA_ISS_GROUP J,
ATTRIBUTE_VALUES_PORTAL K,
PROFILE_TYPE_PORTAL L
WHERE
B.PROFILE_ID = F.AGENCY_ID (+)
AND B.PROFILE_ID = C.AGENCY_ID (+)
AND G.OFFICE_ID (+)= F.OFFICE_ID
AND H.USERID (+)= C.RESP_USR_ID
AND C.ISS_GRP_ID = I.ISS_GRP_ID (+)
AND I.ISS_GRP_ID = J.ISS_GRP_ID(+)
AND 'PROFILE.'||B.PROFILE_ID = K.ENTITY_ID(+)
AND K.ATTRIBUTE_VALUE IS NOT NULL
AND L.PROFILE_TYPE_ID = B.PROFILE_TYPE_ID
AND L.APPLICATION_CD='BDA'
AND NOT EXISTS (SELECT agency_id
FROM TBL_BDA_AGENCY_RESP_REP t
WHERE t.ISS_GRP_ID IN ('%')
AND t.AGENCY_ID = C.AGENCY_ID)
AND K.ATTRIBUTE_VALUE LIKE '%'
AND UPPER(B.PROFILE_NM) LIKE UPPER('%')
AND (to_char(NVL(B.PROFILE_ID,0)) LIKE '%' OR NVL(B.PROFILE_ID,0) IN ('a'))
AND NVL(G.OFFICE_ID,0) IN ('%')
AND (to_char(NVL(C.RESP_USR_ID,'0')) LIKE '%' OR NVL(C.RESP_USR_ID,'0') IN ('k'))
ORDER BY PROFILE_NM
The number of rows in these tables are as follows:
PROFILE_PORTAL -- 2392
TBL_BDA_AGENCY_RESP_REP 3508
TBL_BDA_AGENCY_OFFICE 2151
TBL_BDA_OFFICE 3
USERS_PORTAL 270500
TBL_BDA_USR_ISS_GRP 234
TBL_BDA_ISS_GROUP 2
ATTRIBUTE_VALUES_PORTAL 2790
PROFILE_TYPE_PORTAL 3
The Explain pal nhas given this o/p to me:

Hello Eric,
Here is the code:
SELECT DISTINCT
K.ATTRIBUTE_VALUE AGENCY_ID,
B.PROFILE_NM ,
NVL(G.OFFICE_DESC,'--') OFFICE_DESC,
f.OFFICE_ID,
B.PROFILE_ID,
'%' ROLE,
'%' LAYOUT,
case
WHEN 'flagB' = '%' THEN
NVL(J.ISS_GRP_DESC,'BILLING')
WHEN 'flagO' = '%' THEN
NVL(J.ISS_GRP_DESC,'ORDERING')
WHEN 'flag' = '%' THEN
NVL(J.ISS_GRP_DESC,'BILLING/ORDERING')
else
NVL(J.ISS_GRP_DESC,' ')
END ISS_GRP_DESC,
DECODE(NVL(H.USERID,' ') ,' ','--','&lt;a sbcuid_in=' || H.USERID || ' target=NEW &gt;'||H.FIRSTNAME || ' ' || H.LASTNAME ||
'( ' || H.USERID || ' )&lt;/a&gt;' ) USER_NAME
from
PROFILE_PORTAL B ,
TBL_BDA_AGENCY_RESP_REP C ,
TBL_BDA_AGENCY_OFFICE F,
TBL_BDA_OFFICE G,
USERS_PORTAL H,
TBL_BDA_USR_ISS_GRP I ,
TBL_BDA_ISS_GROUP J,
ATTRIBUTE_VALUES_PORTAL K,
PROFILE_TYPE_PORTAL L
WHERE
B.PROFILE_ID = F.AGENCY_ID (+)
AND B.PROFILE_ID = C.AGENCY_ID (+)
AND G.OFFICE_ID (+)= F.OFFICE_ID
AND H.USERID (+)= C.RESP_USR_ID
AND C.ISS_GRP_ID = I.ISS_GRP_ID (+)
AND I.ISS_GRP_ID = J.ISS_GRP_ID(+)
AND 'PROFILE.'||B.PROFILE_ID = K.ENTITY_ID(+)
AND K.ATTRIBUTE_VALUE IS NOT NULL
AND L.PROFILE_TYPE_ID = B.PROFILE_TYPE_ID
AND L.APPLICATION_CD='BDA'
AND NOT EXISTS
(SELECT agency_id
FROM TBL_BDA_AGENCY_RESP_REP t
WHERE t.ISS_GRP_ID IN (1)
AND t.AGENCY_ID = C.AGENCY_ID)
AND K.ATTRIBUTE_VALUE LIKE '%'
AND UPPER(B.PROFILE_NM) LIKE UPPER('%')
AND (to_char(NVL(B.PROFILE_ID,0))
LIKE '%'
OR NVL(B.PROFILE_ID,0) IN (1))
AND NVL(G.OFFICE_ID,0) IN (1)
AND (to_char(NVL(C.RESP_USR_ID,'0'))
LIKE '%'
OR NVL(C.RESP_USR_ID,'0') IN ('%'))
ORDER BY PROFILE_NM
This is the Query and the query takes some mins. to run in prod environment.
From the Query plan ,I am not able to get any idea for optimization.
Now,Can you tell me which steps I need to follow to run it faster and which all modifications should be made?
Thanks.
