I have done the SAP host agent update using the Auto upgrade method in AIX systems as per the note 1473974 .
Made the changes in the host_profile and restarted the host agent since I made change in host_profile.And I could see host agent updated successfully .
My Doubt is ,do we need to restart host agent in each systems everytime whenever we extract new version in the DIR_NEW .
If so , it seems to be dual work , since we have to login into each server and restart the host agent .
Please advise .
