Home -> Community -> Mailing Lists -> Oracle-L -> RE: Size of segment
Oh Shreepad, you've opened another can of worms there. =)
You shouldn't see any performance difference between 1 extent and 5 extents
or more.
The best option for extent sizing in my opinion is to keep all extents
within a tablespace the same size. This increases the manageability of the
objects within it and eliminates honeycomb fragmentation.

Hi,
Thanks to all those who replied. Just clearing the structure.
I have Hp LVM and the tables and indexes are on different tablespaces and different disks .
Since the growth pattern has changed drastically , the no of extents have increased tremendously . Hence the need to
rebuild the indexes .
We plan to rebuild them into contiguous extents (only question being 1 extent or say 4-5 extents to take care of growth:--- 1 extent every 2 months )
Will the performance differ if they are on 1 extent or 5 extents ( both being contiguous) ?
thanks
shreepad
