Which task would you perform before you run Oracle Universal Installer (OUI) in silent or suppressed
mode for an installation?
A.
Run the root.sh script.
B.
Create the oraInst.loc file.
C.
Create the tnsnames.ora file.
D.
Run the oraInstRoot.sh script.
OraInventory and Orainst.loc are required to install / upgrade oracle and will be used by OUI.
If you plan to install Oracle products using Oracle Universal Installer in silent or response file mode, then you must manually create the oraInst.loc file if it does not exist. This file specifies the location of the Oracle Inventory directory where Oracle Universal Installer creates the inventory of Oracle products installed on the system.
The tnsnames.ora file is a config file that contains network service names mapped to connect descriptors for the local naming method, or net service names mapped to listener protocol addresses.
