Little competition for you all :)
 
It's a two part question:

•     What's wrong with the following piece of expert analysis ?
•     Which well know "Oracle Guru" published this (and continues to display it on his web-page) ?
   
   
  "Sadly, Oracle9i doesn't allow you to specify the value for PCTFREE if you're using automatic space management. This is a serious limitation because Oracle9i can't know in advance about the amount of VARCHAR expansion in a table row, leading to excessive row chaining and poor access performance."
   
  SQL> create table
   2   test_table
   3   (c1 number)
   4  tablespace
   5   asm_test
   6  storage
   7   ( pctfree 20 pctused 30 )
   8  ;
  
    ( pctfree 20 pctused 30 )
      *
  ERROR at line 7:
  ORA-02143: invalid STORAGE option
  
  However, here's an important point. While Oracle9i rejects the PCTFREE and PCTUSED parameters with locally managed tablespaces with automatic space management, it does allow you to enter invalid settings for NEXT and FREELISTS settings"
   
   
   
  You've gotta love it !!
   
  Sorry no clues ....
   
  Cheers ;)
