Primary Key of a table

Dear Oracle experts,

I'd like to know if you would recommend a limit on the number of columns that
you can have in your primary key combination. I was told that a primary key
combination of 5 or 6 columns is inefficient and not elegant. But, my concern
right now is to find out if this is true or if it is just a myth. Would you
know of any Oracle documentation that explains the most efficient way of composing your primary key combination?

Thank you for your help,
Niloufar
