Here is a Web page that explains it pretty well.

You need to decide whether you want your data file to autoextend. I can't
recall if that is the default or not.
You can't set pctincrease for the tablespace and if you think about it,
it doesn't make much sense anyway with uniform extents. You just want it to
take an extent when it needs one. There is no value for taking multiple
extents at a time.
I haven't found a time not to use uniform extents.

This is probably pretty basic, so please keep in mind that Im a developer
and Im trying to pick up more of the DBA side.
I am assuming that the preferred way to create a tablespace in 8i, 9i is as
follows(this is out of OTN docs)
CREATE TABLESPACE lmtbsb DATAFILE '/u02/oracle/data/lmtbsb01.dbf' SIZE 50M
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K;
When you use Uniform Extents you know longer have to worry about tablespace
fragmentation correct? You also do not need to worry minimum,initial,and
next extents correct?
What are some rules of thumb for setting PCTINCREASE(there is another PCT
setting too right)? A DBA I used to work with said you should almost always
use zero for PCTINCREASE. Could someone please tell me why? The default is
like 40?
Is there a time when I should not use Uniform Extents?
Thanks... hope this isnt too basic.
