Ajax(Application Process) used call the Oracle Query of APEX_ITEM.MD5_CHECKSUM

• Java method of Math.random used to get Random no

Example : thisObj = objs[rand_no];
if(thisObj){
checksumId=thisObj.getAttribute('value');
return checksumId;

--- Apex Generate the checksum id per day only one time, I have customized and generated the checksum id per each page refresh.
