Fred,

It is my understanding that NEXT being set to the same value of INITIAL is good idea in terms of keep fragmentation of tablespaces to a minimum. This is also assuming that you keep the extent sizes of other tables in the tablespace to that same extent size. This then means that should a table be dropped for any reason, those extents can easily be reused by another table wanting to extend.

I have a table with rows currently populating. I wish to resize the table for better performance. What is the best way I should figure out how to size my INITIAL and NEXT extent sizes for this table. Is it just: 1) Analyze the table
2) SELECT BLOCKS * (block_size) from dba_tables for the table in question = what the initial size should be set to.
3) What determines what I should set the NEXT extent size to then?

Thank you,
-Fred S.
