Interesting. I remember that in order to make development effort faster, we used to make images of our development boxes with all the required software / applications installed on it. This was pre-virtualization era. But with virtualization, it became a common norm and easier. Now Oracle has also started packaging different development stack on a pre-built Oracle VM
which one can simply download and start using it.
All you need to do is install VirtualBox
to get these pre-built VM's working. Currently Oracle has the following development stacks bundled in a VM with more coming in future -
The Pre-upgrade tool provides a list of items which should be reviewed before upgrading the database (just like a pre-requisites checklist). Basically it reports about the database configuration and parameters etc. that need attention prior to upgrade. The best thing is this script can be run while the database is running on the existing version that means no shutdown required. This allows you to properly plan your upgrade process and avoid unnecessary down time due to pre-requisites missed for the upgrade.
Note: - A few registry$ tables will be created and data would be inserted into them.

. One of the interesting things being that you may not be able to perform JOIN operation. It is being described as the suitable model for cloud service provides (and pay-as-you-go service providers) and big players like Amazon (SimpleDB
), Google (AppEngine Datastore
), Microsoft (SQL Data services
) have already started the offering. There are non-cloud providers too like - CouchDB (more...)
