Installing Oracle 12c on Red Hat Enterprise Linux 6 – Complete Guide

The following is the excerpt of runInstaller.sh file

# 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

#

Which clearly states that if you are missing the .oui file it returns the given message.

Generally, after extracting the downloaded zip files manually we get two directories like database and database(0). The .oui file is hidden so we don't see it using general ls command and File Explorer. You can see it using ls -a command in Linux.

Solution:

Goto the second directory database(0)/install/ and copy the .oui file to the database/install directory.

[oracle@testsrv Desktop]$ cp 'database(0)'/install/.oui database/install

Data Pump utilities are installed automatically during the installation of Oracle Database. It should be working without any issues as long as the environment variables(PATH, ORACLE_HOME) are set properly. To set PATH and ORACLE_HOME variable permanently-

1) Log in as oracle user in the OS.

2) [oracle@ora12c Desktop]$ vi ~/.bash_profile

ORACLE_BASE=/u01/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/product/12.1.0/db_1; export ORACLE_HOME
PATH=.:${JAVA_HOME}/bin:${PATH}:$HOME/bin:$ORACLE_HOME/bin

3)[oracle@ora12c Desktop]$ . ~/.bash_profile

4)Check the value of the variables.

[oracle@ora12c Desktop]$ echo $ORACLE_HOME
/u01/app/oracle/product/12.1.0/db_1
[oracle@ora12c ~]$ echo $PATH
.:/usr/local/java/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/usr/bin:/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/oracle/bin:/u01/app/oracle/product/12.1.0/db_1/bin:/usr/bin:/bin:/usr/bin/X11:/usr/local/bin:/u01/app/common/oracle/bin

5) Try to run expdp

[oracle@ora12c Desktop]$ expdp
