Oracle Instant Client Downloads for Microsoft Windows 32-bit

Oracle Instant Client enables development and deployment of applications that connect to Oracle AI Database, either on-premise or in the cloud.

Overview

The Instant Client libraries provide the necessary network connectivity and advanced data features to make full use of Oracle AI Database. The libraries support popular languages and environments including Python, Node.js, Go, PHP and Ruby, as well as providing access for Oracle Call Interface (OCI), Oracle C++ Call Interface (OCCI), JDBC OCI, ODBC and Pro*C applications. Tools included in Instant Client include SQL*Plus, SQL*Loader and Oracle Data Pump that provide quick and convenient data access.

For more information, see the Instant Client Home page.

For information on the tools and libraries provided for the Pro*C and Pro*COBOL precompilers, see the Precompiler Downloads page.

Permanent links to the latest packages are: Basic, Basic Light, SQL*Plus, Tools, SDK, JDBC Supplement, ODBC

Note:

We strongly recommend that customers install the latest supported Oracle Instant Client for their Oracle Database release. For example, customers should install Oracle Instant Client 19c or 23ai (23.26.x.x) to benefit from the latest features, security updates, and performance improvements. Older versions will be removed in the near future. Customers who require an older version may request it through Oracle Support.

Instant Client Installation for Microsoft Windows 32-bit

See the Instant Client Home Page for more information about Instant Client packages.

Client-server version interoperability is detailed in Doc ID 207303.1. For example, Oracle Call Interface 19c can connect to Oracle Database 11.2 or later. Some tools may have other restrictions.

Download the appropriate Instant Client packages for your platform. All installations require the Basic or Basic Light package.
Unzip the packages into a single directory such as C:\oracle\instantclient_12_2
Add this directory to the PATH environment variable. If you have multiple versions of Oracle libraries installed, make sure the new directory occurs first in the path
Download and install the correct Visual Studio Redistributable from Microsoft. Instant Client versions 19c and 21c packages requires the Microsoft Visual Studio 2017 Redistributable. Instant Client 12.2 requires the Visual Studio 2013 redistributable. Instant Client 12.1 requires the Visual Studio 2010 redistributable.
If you intend to co-locate optional Oracle configuration files such as tnsnames.ora, sqlnet.ora, ldap.ora, or oraaccess.xml with Instant Client, then create a subdirectory C:\oracle\instantclient_12_2\network\admin

This is the default Oracle client configuration directory for applications linked with this Instant Client.

Alternatively, Oracle client configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN to that directory name.

Start your application.
