How to abort an extract using event actions

Hi Folks

I have a requirement to abort the extract when sysdate is entered in the daily_job table.

For this I was simulating an extract in the following way

EXTRACT EVTEST

USERID ID GGSADMIN, PASSWORD XYZ

EXTTRAIL ./dirdat/ET

GETUPDATEBEFORES

TABLE SHEEL.GGTEST, FILTER (ID="SHEEL"), EVENTACTIONS (ABORT);

THE TABLE GGTEST IS SIMPLY (ID VARCHAR2(5), JOIN_DATE DATE).

I start the above extract then I proceed to fire the following insert in the ggtest table

SQL> INSERT INTO GGTEST VALUES ('SHEEL','01-AUG-2014');

SQL> commit;

when I check the status of the extract it's still running . It has not ABENDED or ABORTED.
