Sean,
We use Oracle on NT with autoextend.
We also have automated disk space remaining monitoring with notification to
mobile phones.
However, I still configure the maxsize such that the sum of the maxsize on
each disk is less than the available space on the disk.
Consider the following script as a simple way of measuring current and
maximum per disk (if only it was easy to work out disk size within Oracle):
-- space_by_disk.sql
-- 27-Sep-2001 , Bruce Reardon : Created.
-- Assumptions
-- That DB is on NT as uses first character of filename to group by
disk name.
COLUMN curr_mb FORMAT 999,990.9
COLUMN max_mb FORMAT 999,990.9
select
substr ( file_name ,1,1) disk,
sum (bytes / 1024/1024) curr_mb ,
sum (maxbytes / 1024/1024) max_mb
from
dba_data_files
group by
substr ( file_name ,1,1)
;
Regards,
Bruce Reardon

Sean,
I assume from your question that you are already using autoextend on your
tablespaces.
I personally do not use that option and therefore the chance of a tablespace
expanding above available disk space never occurs.
However in the event of my running a massive insert or import when I was not
sure how much space would be used I might use autoextend until the creation
was over and then turn autoextend off

Wondering what folk out there do to manage disk space usage by tablespaces.
Is it common/bad practice to have MAXSIZE unlimited and/or MAX_EXENTS set to
a value which if reached would be larger than disk capacity and therefore
regular observation of space is required, or is there a better way to do
this?
Sean :)
