Various operations need to be performed with root privileges at this time. For example, you must have root privileges to be able to write the OUI inventory.
If you have root privileges, continue with the required operations.
If you do not have root privileges, run the /tmp/orainstRoot.sh Bourne shell script from another terminal window before proceeding with the install. To successfully run this script you must be logged on as user with root privileges.
The OUI inventory is where the inventory location is created. The Inventory location, <orainventory>, is located at /Program Files/Oracle/Inventory on NT and at the same level as the first <Oracle Home> on Solaris. It is the location for the Oracle Universal Installer's bookkeeping. Information about the inventory location is written into HKEY_LOCAL_MACHINE/SOFTWARE/ORACLE/inst_loc and /var/opt/oracle/oraInst.loc (requires root permissions).
Note: You should not exit the install in order to run this script. Exiting the install removes this script. The Unix Installer Location screen only appears the first time you install.
