Getting "ORA-29024: Certificate validation failure" error while using UTL_HTTP.begin_request functio

Hi All,

I am getting "ORA-29024: Certificate validation failure" error while using UTL_HTTP.begin_request function in EBS database v11.2.0.4.0. below is the code I used. (masked actual data with xxxxx in some places)

This is first time we are using this function. Let me know if any setups are required.

Code:

DECLARE

v_http_req utl_http.req;

BEGIN

dbms_output.put_line('Start..');

v_http_req := UTL_HTTP.begin_request('https://xxxxxxxxx.bigmachines.com' ,'POST' ,'HTTP/1.1');

dbms_output.put_line('End..');

EXCEPTION

WHEN OTHERS THEN

dbms_output.put_line('Error: '||SQLERRM);

END;
