If you mean PL/SQL procedures, you can define arguments as optional by giving them a default value:

create or replace procedure foo
(

	arg1 number,
	arg2 varchar2 default null,
	arg3 integer

)
... if arg2 is not null then ... -- caller passed a value

and in the caller:

foo(arg1 => 10, arg3 => 100);
