RE: Oracle 8.1.17 extent management

I'd be careful about the 1M extent size for all objects. Make sure you understand the size requirements for all of your objects. Some objects will require much more space and even though the number extents is not the big deal that it was in the past, it's still a good idea to make sure tables are extended during normal user activity.

Locally managed fixed 1 meg extents (initial 1m, next 1m, pctincrease 0) works real well.

In have a customer still runing 8.1.7. They were having performance issues which appeared to be due to frgmentation. An export and import solved the performance issue.
They are due to move to Orcale 10 soon, but in the mean time what can they do to minimise fragmentation on 8.1.7.
Move to locally managed tablespaces? Change the next extent values(which appear to be very small) ?
