Hmmmm ... a 9.0.2 database ... would you please verify that number (I susect it's a 9.2.0.x as Oracle went from 9.0.1 to 9.2.0 and 9.0.2 is a designation for Application Server, not database)

There are a umber of things you could do, but there are an awful lot of decisions that need to get resolved first. You might find a scan of the Oracle Backup and Recovery Concepts manual useful - for 9.2 it's at

http://www.oracle.com/pls/db92/db92.docindex?remark=homepage ... and in PDF http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96519.pdf

You don't seem to need up-to-the-minute recovery, so basically I'd almost suggest that this is throw-away and you could get away with a cold backup (shutdown database, copy all related files, restart). That can be handled by a relatively simple script. Just remember to shutdown first (or you have a 99.9999..% chance of unsync'd and therefore probably corrupt files) and copy ALL related files.. Do that periodically (daily) and recovery is to that point in time simply by copying the files back.

Since this is but one of several variations, I strongly suggest you spend some time reading the manual to decide what is right.

By the way - I've dropped the comp.database.oracle.tools (cdo.tools) and cdo.marketplace as the question is totally off-topic for those newsgroups. Since the same group of people reads all the newsgroups, I suggest your replies and further interaction be kept to cdo.server ... for more, see http://orafaq.com (I, for one, don;t like seeing the same question over and over.)
