How to retrieve first update SQL statement initiator (locking)

Question

Hi!
i have a table called as
test ( A number, B varchar2(10));
1) inserted 1000 records
2) update test set A=A where A=1;
3) open new session issue update test set B=B where A=1;
reselt lock;
opened again a new session and issued this statement
COLUMN blocker format a15
COLUMN blockee format a15
SELECT (SELECT username || '.' || a.SID FROM v$session
WHERE SID = a.SID ) blocker, ' is blocking ',
(SELECT username || '.' || b.SID FROM v$session
WHERE SID = b.SID ) blockee, ' from executing: ',
(SELECT sql_text FROM sys.V_$SQL
WHERE address =
(SELECT sql_address FROM v$session WHERE SID = b.SID ) )
FROM v$lock a, v$lock b
WHERE a.BLOCK = 1 AND b.request > 0 AND a.id1 = b.id1 AND a.id2 = b.id2;
Result as:-
BLOCKER 'ISBLOCKING' BLOCKEE 'FROMEXECUTING:'
(SELECTSQL_TEXTFROMSYS.V_$SQLWHEREADDRESS=(SELECTSQL_ADDRESSFROMV$SESSIONWHERESI
SYS.159 is blocking SYS.144 from executing:
UPDATE TEST SET B=B WHERE A=1
question is how can i retrieve my first update sql statement i:e (initiator)....?
as (UPDATE TEST SET A=A WHERE A=1;)

Since releasing 10.2.0.1 several years ago Oracle has released patches to 10.2.0.2, 10.2.0.3, and 10.2.0.4. I would highly recommend you read the patch notes and get your system current.
I note that you did not answer my two follow-up questions leading me to assume you do not have the license to look at the tables and views supporting ASH and AWR. Without them I do not believe you can retrieve the information you seek.
I no longer have 10gR2 on my laptop so I am not sure but take a look at gv$session.
Do you have columns named "BLOCKING_SESSION_STATUS", "BLOCKING_INSTANCE" and "BLOCKING_SESSION"? If you do that might lead you to a way you could track it down via gv$sql.
