Server Administration :: Create An Index Using Parallelism?

We are trying to create an index using parallelism. The table contains 24 Million row. But It takes very long time. Also we are unable to see any sessions confirming that the index creation is using parallelism. The creation goes on for more than 3 hours. SQL statement executed :

CREATE INDEX ANT.ANT_OM_TRAN ON APPS.ANT_OM_TRAN_INDX (last_update_date) PARALLEL 4 TABLESPACE APPS_TS_IDX;

I found out the session using the query

select sid,serial#,program,module,osuser,username,machine,inst_id,sql_id
from gv$session where type not in ( 'BACKGROUND') and machine='APCUSDE'
and osuser='applmgr' and program like 'sqlplus%' order by logon_time ;
select * from gv$sqltext where sql_id='akrr2ww1ukq5z';

The given queries were used to check if it was using parallelism, but i was unable to find anything.

SELECT QCSID, SID, INST_ID "Inst", SERVER_GROUP "Group", SERVER_SET "Set",
NAME "Stat Name", VALUE
FROM GV$PX_SESSTAT A, V$STATNAME B
WHERE A.STATISTIC# = B.STATISTIC# AND NAME LIKE 'PHYSICAL READS'
AND VALUE > 0 ORDER BY QCSID, QCINST_ID, SERVER_GROUP, SERVER_SET;
SELECT * FROM V$PX_PROCESS;

how can i make sure that, it is using parallelism.
