Hi Sundaresh,
I am not sure exactly if this helps...but let me give an idea...
I assume you have a script which you wanted to run on background, only one instance of it.

# inside the script, you will add these few lines to check if the script is already running
Code:
COUNT=`ps -ef SCRIPT_NAME | wc -l`
if [ "$COUNT" -eq 0 ]
then
  # run the script
 /full/path/SCRIPT_NAME &
else
  echo "Already an instance of the script is running"
fi
exit 0
