Hello Jay
How about building an historical DB and keeping the data there.
It will not overload the production instance, will be available online if
you need something, you will migrate it to new versions of Oracle so
compatibility will not be an issue and you can implement table changes on

Another poor man's solution would be to unload the tables into flat files and attach
to them as needed using Oracle's external table feature from 9i. That solution
should hold for quite a while into the future since the external table function is

Remind the management that in the future there might also ba a change

unreadable by the new tape drives. If possible save the data to a text

And finding something to play that CD in 50 years, much less understand the data format, will be like finding something to play an old 78 now.
78. How's that for showing my age! I even had a 16 once. And a 4-track (pre 8-track).

some data on media which would last 10,000 years. I suggested chisels and stone

Hi Tim
We just signed a contract for external storage system from EMC and the
configuration is going to be:
Regular servers - connect as Nas
Database servers - connect as San.
If I remember correctly Nas use SCSI connections while San use fiber.

FWIW, what we just implemented (because senior management refuses to approve
additional storage on the grounds that making the database larger will
affect performance - aaargh!) is

just make sure you are not around when, after several Oracle upgrades, and
they want to import one of these files back that they discover that the
current release of import can no longer read the older version of the .dmp

Here is my thought for your consideration, evisceration. A fundamental
principle of backup and recovery is that you can only consider a backup to
be good if you've tested a recovery. Why not apply this principle to data
archiving? In other words, when you upgrade to a new Oracle
Well, if worst comes to worst we can always install an earlier version on a
box and import it there.
But the reason we can't get more storage approved still has me shaking my
head...

Prem,

would re-visit the requirement. Why do you feel the need to delete the
data from the database? What is the purpose for this type of
requirement? It would be far easier to modify the requirement than to do
what you are thinking of doing.
Adding
columns to database tables
This is adata-archival requirement, not a
data-purge requirement. It only resembles a purge requirement based on the
multiple-database-migration strategy you outlined. There are
alternatives...
Depending on the volume of data in your database
and your availability requirements,
the data back because of software
compatibility issues.

Someone asked about this 3 weeks ago. Here's my take
on archiving data. I don't expect everyone to agree with this,
but nonetheless, I have an opinion. :)
