ORACLE USER用戶角色限制用戶查看和執行功能而不修改它

Question

對於新手問題，我很抱歉。我在oracle中創建只讀用戶。我想限制他只是爲了查看和執行一個函數或過程。我不希望他修改那些func或proc。請幫助我如何實現這一目標。

非常感謝

-- As sysdba: 
-- 1) create an user account 
create user <username> identified by <password>; 
-- 2) allow user to log in 
grant create session to <username>; 
-- 3) allow user to execute a single procedure in other schema 
grant execute on <other_schema.procedure_name> to <username>;
