Your cursor loops through all results, then after the last fetch prints the 
'not found' message; it's not doing anything with the data it does select. Add 
these lines and you'll see what I mean. NOTFOUND really means END OF FETCH...


BEGIN      
      OPEN categories_cur(p_name);
      LOOP
            FETCH categories_cur INTOv_describe;
            IF(categories_cur%NOTFOUND)
            THEN
               DBMS_OUTPUT.PUT_LINE('categories_cur%NOTFOUND is true');  
[Diwakar] I guess the above IF stmnt would cause
          an infinite loop. So instead it should be 
          "EXIT WHEN categories_cur%NOTFOUND"
            ELSE
               DBMS_OUTPUT.PUT_LINE(v_describe);
            END IF;   
END test;
