Hello Lakshmanan,
I am not sure why you would want to give execute permission to group and others for every file.
In any case, I am assuming you have added the parameter / user settings in your Process Orchestration system. Add the umask setting in /home/<sid>adm/.profile file and restart the PO java system.
Another peculiar thing would be, that the umask functionality works by subtracting the umask value from 777 for directories and 666 for regular files. So I think if you gave umask as 003, you will get 774 for directories that are created and 663 which is weird permission to provide for regular files.
Regards,
Siddhesh
