Introduction

In this article I will explain cause and resolution of “System.Data.OracleClient requires Oracle client software version 8.1.7 or greater.” error

Cause

This error generally occurs when you deploy an application on the server that access Oracle database using “System.Data.OracleClient” library and it doesn’t find the library on the server.

Resolution

To resolve this error you need to install Oracle Data Access Components (ODAC) with Xcopy deployment on the server which enables Oracle Data Provider for .NET (ODP.NET). Please follow these steps to install ODAC on the server

Step 1: Download ODAC component

For 32-bit download ODAC1120320Xcopy_32bit.zip from here

For 64-bit download ODAC112021Xcopy_x64.zip from here

You have to sign up to download these from oracle.com. I will download and install ODAC for 64-bit.

Step 2: Extract downloaded zip file anywhere on the system for example on the Desktop

Step 3: Open Command Prompt (cmd) and run following command to change directory to the extracted folder:

cd C:\Users\deepak\Desktop\ODAC112021Xcopy_x64

Step 4: Run following command in the Command Prompt to install Oracle Data Access Components

install.bat odp.net20 c:\oracle\11.2\odac odac11

Step 5: Add following paths of the installed ODAC components in the Path environment variable of the system

C:\oracle\11.2\odac

C:\oracle\11.2\odac\bin

Follow these steps to add paths to the environment variable

Step 5.1: Right click on “Computer” and select “Properties” to open the System properties

Step 5.2: Click on “Advanced system settings” to open “System Properties”

Step 5.3: Click on “Environment Variables” button under “Advanced” tab to open “Environment Variables” window

Step 5.4: Double click on the “Path” variable in the “System Variables” (scroll down if it’s not visible) section to edit the “Path” variable

Step 5.5: Add C:\oracle\11.2\odac;C:\oracle\11.2\odac\bin; at the beginning in the “Variable value” TextBox

Step 5.6: Close all the windows by clicking on “OK” button

Step 6: Restart your system.
