Effect of changing the profile parameter
1]I wanted to know that when I am modifying a profile(either default profile or Instance profile) will there be an immediate effect on my system after modifying a profile as mentioned above.
2]Also I wanted to know that after a default profile has been created and activated in my system ; can I add additional parameter in my default profile after the default profile has been created or whether I have to add that additional parameter in my instance profile.
4] What are the problems faced by the users which are logging into the production system after changes are made in profiles in productive system.
3] Please mention the further steps to do after importing the profiles(DEFAULT,INSATANCE,START) in my database.
