How to find the ideal size of the extent for a locally managed tablespace uniform size ? Oracle is recommending only three extent sizes: 128k, 4m, and 128m. See white papers at technet.oracle.com for further details on the new philosophy. Dennis Williams DBA Lifetouch, Inc. dwilliams_at_lifetouch.com

Hi folks,

Actually I have 8.0.5 and will install 8.1.7 in the weekend, and would like to have somethings clear.

Actually I have just 2 tablespaces, but planning to make one for each application system,
will be like 7.

Of course will make all kind of backups, cold, hot including redo logs, password files, parameter files and archives.

What I am planning to do is make an export of the user owner of the all objects and
make and import in the new DB.

How to find the ideal size of the extent for a locally managed tablespace uniform size ?
As far as I know, not much, the import will create the same tablespaces where the objects exists in the old DB in the new DB. Now, if I use an alter table move tablespace to move the tables to the new LMT tablespace, will it use the extent size of the new TBS or will remain with the old one ?
I'm considering to recreate all the indexes.
Is it a good idea to have an TBS for each APP system ?
What are the consequences of having all of them with different extent size ?
If by any chance some of them are going to have the same extent size wouldn't be better to put them in one TBS ?
Any tips for sizing of the SGA, shared pool, log_buffers, sort_area_size ?
Planning make db_block_size 8k
My second step will be implement Forms Server, anything to include in the installation of have in mind from now ?

My DB is transactional, not that heavily, like 40 users, but like 12 of them are remote.

Hardware
Compaq
2 Pentium III processor 800 mhz
6 Hard Drive 9.1 GB - raid 5
1 GB Memory
Win 2000 server

Thanks in advance and sure that your help will be very, very useful.
