Hi, I used the following approach and it worked fine for me while the database was not very big:
1. Create and run standby database on another machine. 2. Periodically stop standby, create a copy, start again and activate it 2a. If this is not a first pass, shutdown report database 3. Rename standby database and mount/open it as report database 4. restore standby from copy, continue standby recovery. Everything was automated with shell scripts and worked well.

You will need another approach, presumably materialized views/snapshots for bigger database.

How are you all creating reporting databases? We currently have an OLTP database and we wish to create a reporting database from it. As I see it, we have the following options:

1. Create the reporting database as a Standby database. I don't think that this will work since the database must be up and not in standby mode.
2. Use Oracle replication. I have heard it is cumbersome and has trouble keeping up with lots of transactions.
3. Snapshots/materialized views.
4. Beef up our current machine so that it can handle OLTP transactions and reports.
5. Since we are using a BMC disk array, we could break the mirror periodically and mount the disks on a new machine.
6. Other 3rd party replication products.
7. We could probably use some type of import/exports.

How are the rest of you doing it? Are there any other options that I forgot?

Thanks,
Tom
