I don't think partitions are clearly documented anywhere. Here is some SQL

columns, but I wanted you to see something that works.
add partition sum_fy_28
values less than ('FY',

I think you can relatively safely argue that Oracle is spending 90% of it's

The only way this would have worked under 8i is if you had already
created a dummy rollback segment in the SYSTEM tablespace. Something
like this should work (before or after the CREATE TABLESPACE
rollback_space)

On a slightly different approach, is it possible to update the column to the

If the log buffer is at least 4MB, then increasing
it will not help, rather it may hurt. The log buffer is flushed when any of the

(3) every 3 seconds
(4) when a checkpoint occurs
(5) when a commit occurs.
