Hi DBA gurus,
One of the application is going live .At presenr data is 15GB and will
grow more by 10 GB in year time. What is the right approach of
tablespace design having more files of smaller size(10 files of 2 GB )
or less file of bigger size (3 files of 8 gb ).
No tables
, then key in on v$waitstat. You might get a copy of Gaja's book
Oracle Performance Tuning 101. Then you'll really impress him.
If you have everything on a single drive, tablespace design probably
isn't going to buy you much in terms of performance. Myself, I would tend to
tune the memory buffer cache
?

Hi John,
After the sort phase is complete, Oracle will trigger memory
de-allocation and the OS will go at work again.

I seem to recall a post from Steve Adams not too long ago about
this. As I recall, free() is not called immediately, but

Well, not quite. SORT_AREA_SIZE specifies the maximum
amount, in bytes, of memory to use for a sort. After the sort is complete
and all that remains

Hi Chris,
Yes there may be 'rules' like this, but realistically who has 64GB to spend on disk space? I have one huge table similar to what you describe. My temp tablespace is 20GB only because I have the disk. Maybe you can take the route
I'd be tempted to make it 4 times your largest expected working set, but how you
arrive at that figure is beyond me...

What's your experience about the temporary table
design? I read Michael Ault's Orcale8 Administartion

First let me say that I have a TON of respect for Mike and count him as a

Steve,
Thanks for reminding me of that one other operation that does also take up
temp. Again, I think that depends on how often you calculate statistics if
your using partitioning. We do statistics once a week, and do it partition by
partition so it does not take up that much.

Kirti:
The server is solely used for the Oracle Database
and it has 2GB Ram. I didn't increase sort_area_size
too much because I thought the table is so big, and
probablay I could not run them in the memory. That's
why I just try the temp tablespace.
Thanks,
Chris
I think you missed analyze operation. It is for this command is 4xtable
size may be required. Also space for temporary tablespaces can be on very
cheap disks.
