The procedure to set up a web install is as follows:

1. Copy the disk to a stage area.

2. Publish the root of the stage area on a web server.

3. Start the Oracle Universal Installer and point to the http URL for the

products.xml file.

4. From this point on the installation will run as if the install media was on

a local device, the only difference will be that all the required files will be
dispatched from the web.

Recovering a lost Inventory
What should you do in case a central inventory gets lost? There are a couple of
scenarios here; you could have a valid Oracle Home either intact or restored from a
backup, but the central inventory is lost, if this is the case Oracle will work, but you
will notice the missing inventory when you try to do an upgrade or apply a patch. In
Oracle 10gR1 and earlier releases there is no other option but to restore the inventory
from a backup, so you should include in your backup policies a periodic ORACLE_
BASE backup which includes the different Oracle Homes and the central inventory.
In Oracle 10gR2 and 11gR1, you can register it using the following procedure:

Change to the oui/bin directory inside the target Oracle Home:

cd $ORACLE_HOME/oui/bin
