Oracle Database Client silent installation on Windows

Here is how I have installed Oracle Client on my personal Windows 8.1 computer:

C:\>systeminfo | findstr sys
Nom du systeme d'exploitation:              Microsoft Windows 8.1
Version du systeme:                         6.3.9600 N/A version 9600

Option regionale du systeme:                fr;Francais (France)
Emplacements des fichiers d'echange:        C:\pagefile.sys


This is not Windows 8.1 Pro or Enterprise which are the only supported version Windows 8 for this Oracle Client according to Oracle Database Client Installation Guide 12c Release 1 (12.1) for Microsoft Windows but Oracle Universal Installer (OUI) does not check the Windows edition and I assume that the installation process is the same for all supported Windows editions.

I have first downloaded installation media from OTN and unzipped it into a staging area (assuming 7-Zip is installed in defaut location):

c:\temp\oc>"c:\program files\7-zip\7z" x

7z output should end with:

Everything is Ok

Folders: 655
Files: 1103
Size:       941329988
Compressed: 925039944

I have opened a command window cmd.exe in administrator mode and to install Oracle Client with Administrator option in C:\oracle\oc121 directory I have run (command is edited for better formating – used command line has all arguments on one single line):

c:\temp\oc>cd client

c:\temp\oc\client>setup -silent 

This command has opened a new window named “Oracle Universal Installer” which has displayed a lot of INFO messages and has ended with:

L'operation installation de Oracle Client 12c a reussi.
Pour plus de details, consultez 'C:\Program Files\Oracle\Inventory\logs\silentInstall2015-12-18_11-17-10AM.log'.
Successfully Setup Software.

Appuyez sur Entree pour quitter...

What is essential is that this output ends with something similar to (in the above output this output is partially in French):

The installation of Oracle Client 12c was successful.
Please check 'C:\Program Files\Oracle\Inventory\logs\silentInstallXXX.log' for more details.
Successfully Setup Software.

I have checked installed version of SQL*Plus from a new cmd.exe window without administrator privileges:

C:\>sqlplus -v

SQL*Plus: Release Production

C:\>where sqlplus


I have checked Oracle inventory with following commands from same cmd.exe:

C:\>set ORACLE_HOME=c:\oracle\oc121

C:\>%ORACLE_HOME%\opatch\opatch lsinv

Aucun patch temporaire n'est installe dans ce repertoire d'origine Oracle Home.


OPatch succeeded.


Note the mix of English and French output (likely due to French Windows settings of my PC).

I have also checked that OUI has added to Windows Registry the new Oracle Client Home:

C:\>reg query hklm\software\oracle

    inst_loc    REG_SZ    C:\Program Files\Oracle\Inventory


C:\>reg query hklm\software\oracle\KEY_OraClient12Home1

    ORACLE_HOME    REG_SZ    c:\oracle\oc121
    ORACLE_HOME_NAME    REG_SZ    OraClient12Home1
    ORACLE_GROUP_NAME    REG_SZ    Oracle - OraClient12Home1
    ORACLE_BUNDLE_NAME    REG_SZ    Enterprise
    OLEDB    REG_SZ    c:\oracle\oc121\oledb\mesg
    SQLPATH    REG_SZ    c:\oracle\oc121\dbs
    ORACLE_BASE    REG_SZ    c:\oracle
    MSHELP_TOOLS    REG_SZ    c:\oracle\oc121\MSHELP


Note the default NLS_LANG setting matches my French Windows settings.

I have also tested connection to a database running on Oracle Linux virtual machine with Easy Connect syntax:

C:\>sqlplus test/test@ol6twsa0:1521/CDB0

      Do you know that this is the first client installation instructions, that actually worked? I searched for instructions a year ago, then gave up and postponed the project, then searched again recently.

      Every other article points to other Oracle downloads, with instructions for a manual installation that never works.

      This is the first time I’ve been able to replace the 11x client with 12x. Thanks.
