Installing Oracle 12c on Red Hat Enterprise Linux 6 When I try to ./runInstaller I get this error message:


  Source location is incomplete. Make sure you have downloaded and extracted all the relevant archives.


I have two database unzip folders, database and database(0).

I copied database(0)/install/.oui to database/install, but the error message does not disappear.

This is the part of runInstaller:

# Abort the install, if install/.oui file is not found in the stage area
#
if [ ! -f $CMDDIR/install/.oui ]
then
        echo "Source location is incomplete. Make sure you have downloaded and extracted
all the relevant archives."
        exit 1
fi

#


This is the list of my database directory:



Certainly I have the .oui in database/install.

What can I do to resolve this error?
Extracting the Installation Files


  Oracle RDBMS software is available as two archive files. Ensure that
  you extract both the archive files to the same directory.


Not just install/.oui, everything.
