How to Find the Download Link
To find the download link for the Oracle client software version 8 .1.7 or greater free, you need to follow these steps:
Go to the official website of Oracle at https://www.oracle.com.
Click on the "Menu" icon at the top right corner of the page and select "Database" from the drop-down menu.
Click on the "Download" button under the "Oracle Database" section.
Scroll down to the "Oracle Database Client" section and click on the "See All" link.
Select the version of the Oracle client software that you want to download from the list. For example, if you want to download version 19c, click on the "Oracle Database 19c Client (19.12) for Microsoft Windows (x64)" link.
Log in with your Oracle account or create a new one if you don't have one.
Accept the license agreement and click on the download link for the file that matches your system and preference. For example, if you want to download the instant client in basic mode for Windows 64-bit platform, click on the "oracle-instantclient19.12-basic-windows.x64-19.12.0.0.0.zip" link.
Save the file to your desired location on your system.
How to Verify the Download Integrity
To verify the integrity of the downloaded file, you need to check its checksum value and compare it with the value provided on the website. The checksum value is a unique code that is generated from the file content and can be used to detect any corruption or modification of the file. The checksum value can be calculated using various algorithms, such as MD5, SHA-1, SHA-256, etc. The website usually provides the checksum value for each file using one or more of these algorithms.
To check the checksum value of the downloaded file, you need to follow these steps:
Download and install a checksum utility program on your system, such as WinMD5Free, HashCalc, etc.
Run the checksum utility program and browse to the location of the downloaded file.
Select the algorithm that matches the one provided on the website. For example, if the website provides the MD5 checksum value, select MD5 as the algorithm.
Click on the "Calculate" or "Verify" button and wait for the program to generate or compare the checksum value.
If the checksum value matches the one provided on the website, it means that the file is intact and valid. If not, it means that the file is corrupted or tampered with and you need to download it again.
Step 3: Install the Oracle Client Software on Your System
The third step is to install the Oracle client software on your system. The installation process varies depending on whether you have downloaded the instant client or the full client. We will explain each case in detail in the following sections.
How to Extract the Image Files and Run the Installer
If you have downloaded the full client, you need to extract the image files and run the installer to install the Oracle client software on your system. The image files are usually in ZIP or TAR format, and they contain one or more files with the extension .img or .jar. These files are self-extracting and self-installing files that can be executed directly or through a command prompt. To extract the image files and run the installer, you need to follow these steps:
Extract the ZIP or TAR file to a temporary location on your system, such as C:\temp.
Go to the extracted folder and locate the image file with the extension .img or .jar. For example, if you have downloaded the Oracle Database 19c Client for Windows 64-bit platform in administrator mode, you will find a file named winx64_19c_client_admin.img.
Double-click on the image file to launch the Oracle Universal Installer. Alternatively, you can open a command prompt and navigate to the extracted folder and run the image file with the java command. For example, java -jar winx64_19c_client_admin.img.
Follow the instructions on the screen to complete the installation process. You will need to provide some information, such as the destination folder, the installation type, the components to install, etc.
When the installation is finished, click on the "Finish" button and close the Oracle Universal Installer.
How to Configure the Oracle Net Services and Test the Connection
If you have downloaded the instant client or the full client, you need to configure the Oracle Net Services and test the connection to verify that the Oracle client software is working properly on your system. The Oracle Net Services are a set of components and tools that enable you to establish and manage network connections between your system and an Oracle database server. To configure the Oracle Net Services and test the connection, you need to follow these steps:
Create or edit a file named tnsnames.ora in your Oracle client software installation folder or in a folder specified by the TNS_ADMIN environment variable. This file contains information about the Oracle database servers that you want to connect to, such as their names, addresses, ports, service names, etc. You can use a text editor or a tool like Oracle Net Manager to create or edit this file. For example, if you want to connect to an Oracle database server named ORCL on a system with IP address 192.168.1.100 and port 1521, you can add an entry like this in your tnsnames.ora file:
ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = ORCL) ) )
Set or modify some environment variables on your system to enable your applications to use the Oracle client software. The environment variables that you need to set or modify are: - PATH: This variable specifies the directories where your system looks for executable files. You need to add the Oracle client software installation directory or the instant client directory to this variable. For example, if you have installed the Oracle client software in C:\oracle\client, you need to add C:\oracle\client\bin to the PATH variable. - ORACLE_HOME: This variable specifies the directory where the Oracle client software is installed. You need to set this variable to the Oracle client software installation directory or the instant client directory. For example, if you have installed the Oracle client software in C:\oracle\client, you need to set ORACLE_HOME to C:\oracle\client. - TNS_ADMIN: This variable specifies the directory where the tnsnames.ora file is located. You need to set this variable to the directory where you have created or edited the tnsnames.ora file. For example, if you have created or edited the tnsnames.ora file in C:\oracle\network\admin, you need to set TNS_ADMIN to C:\oracle\network\admin. You can set or modify these environment variables using the System Properties dialog box or the command prompt on your system.
Test the connection using a tool or an application that uses the Oracle client software, such as SQL*Plus, SQL Developer, etc. You need to provide the username, password, and database name that you want to connect to. For example, if you want to connect to the ORCL database using SQL*Plus, you can run a command like this:
sqlplus scott/tiger@ORCL
If the connection is successful, you will see a message like this:
Connected to: Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 - Production Version 19.12.0.0.0
If the connection fails, you will see an error message like this:
ORA-12154: TNS:could not resolve the connect identifier specified
In that case, you need to check your tnsnames.ora file, your environment variables, and your network settings and try again.
