Home -> Community -> Mailing Lists -> Oracle-L -> RE: archive old data
Nancy
I would second Mladen's recommendation that you review Princeton Softech. Another consideration that I didn't see anyone mention is that most people discussed data archiving on a table-by-table basis. But Oracle is a RELATIONAL database and it rarely does any good to just archive a few isolated tables. That was one aspect of Softech that impressed me was how well it handled the requirement to archive related sets of data.

Partitioning in itself is not a complete solution, because it doesn't keep
track
of changes. You may also want to try Princeton Softech, which has a great
product
that archives things directly to CD juke box and keeps track of what is
where and changes
needed in order to get it back online, if necessary. The URL is:
http://www.princetonsoftech.com
They have some great products there. While I was working for Oxford, I
worked with
their product caled "Move For Servers" which creates logically conistent
subsets (it
follows RI). I was very impressed with the product as well as with the
quality of the
support staff. Those guys are good, especially Kevin Hamson.
