Session getting locked when running jobs

Question

Hello:
I am trying to kick of jobs:
DECLARE
X NUMBER;
BEGIN
SYS.DBMS_JOB.SUBMIT
( job => X
,what => 'ABC.A1;'
,next_date => to_date('16/10/2008 08:05:00','dd/mm/yyyy hh24:mi:ss')
,interval => 'TRUNC(SYSDATE+30)'
,no_parse => TRUE
SYS.DBMS_OUTPUT.PUT_LINE('Job Number is: ' || to_char(x));
END;
commit;
DECLARE
X NUMBER;
BEGIN
SYS.DBMS_JOB.SUBMIT
( job => X
,what => 'ABC.A2;'
,next_date => to_date('16/10/2008 08:05:00','dd/mm/yyyy hh24:mi:ss')
,interval => 'TRUNC(SYSDATE+30)'
,no_parse => TRUE
SYS.DBMS_OUTPUT.PUT_LINE('Job Number is: ' || to_char(x));
END;
commit;
The first job starts fine. But the second job in encountering a session-locked error.
What am I doing wrong?

With this query, you can show the sql blocker and blockee.
Regards Salim.
SELECT 'BLOCKER: '||BW.HOLDING_SESSION||'('||SB.USERNAME||') MODE: '||MODE_HELD||
        ' - SQL: '||BQ.SQL_TEXT BLOCKER,
       'BLOCKEE: '||BW.WAITING_SESSION||'('||SW.USERNAME||') MODE: '||MODE_HELD||
        ' - SQL: '||SQ.SQL_TEXT  BLOCKEE
     FROM DBA_WAITERS BW, V$SESSION SB, V$SESSION SW, V$SQLTEXT BQ, V$SQLAREA SQ
     WHERE BW.HOLDING_SESSION = SB.SID
    AND BW.WAITING_SESSION = SW.SID
    AND SB.PREV_SQL_ADDR = BQ.ADDRESS
    AND SW.SQL_ADDRESS = SQ.ADDRESS ;
