Installation guide

14.You will see this
window only if no
Oracle inventory exists
yet (e.g. first installation
of any Oracle product on
this machine).
Inventory location: The
text in this window is
somewhat confusing.
This is not about where
to install Oracle
software, this is only
about the inventory
database for the Oracle
Universal Installer, so
that it can keep track of
which Oracle software
and which components
are installed and where.
The suggested place is just under ORACLE_BASE. We recommend to accept the default.
15.You will see the
following two windows
only if there is no file
/etc/oraInst.loc
yet on your machine,
which this step will
create.
The second sentence in
this window is useless,
since you should never
start the Oracle
Universal Installer as
root. What it should say
is that if you leave the
field blank only the user
you are running the
installation as will be
able to update the Oracle
software.
We put the group
oinstall in the field, but since only user oracle is a member of this group by default this is
equivalent to leaving it blank, but leaves you with the flexibility to add user names to this group
later should you wish so.
