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 ;)
