Oracle Instant Client Downloads for Linux x86 (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

See the Instant Client Home Page for more information about Instant Client. For information on the tools and libraries provided for the Pro*C and Pro*COBOL precompilers, see the Precompiler Downloads page.

The installation instructions are at the foot of the page.

Client-server version interoperability is detailed in Doc ID 207303.1. For example, Oracle Call Interface 19.3 can connect to Oracle Database 11.2 or later. Some tools may have other restrictions.

Permanent links to the latest packages are: Basic (.zip), Basic (.rpm), Basic Light (.zip), Basic Light (.rpm), SQL*Plus (.zip), SQL*Plus (.rpm), Tools (.zip), Tools (.rpm), SDK (.zip), SDK (.rpm), JDBC Supplement (.zip), JDBC Supplement (.rpm), ODBC (.zip), ODBC (.rpm)

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 Linux (32-bit)

For general Instant Client information, see the Home Page.

ODBC users should follow the ODBC Installation Instructions.

Client-server version interoperability is detailed in Doc ID 207303.1. For example, Oracle Call Interface 19.3 can connect to Oracle Database 11.2 or later. Some tools may have other restrictions.

Installation of ZIP files:

Download the desired Instant Client ZIP files. All installations require a Basic or Basic Light package.
Unzip the packages into a single directory such as /opt/oracle/instantclient_19_3 that is accessible to your application. For example:

cd /opt/oracle unzip instantclient-basic-linux-19.3.0.0.0dbru.zip

Prior to Version 18.3, create the appropriate links for the version of Instant Client, if the links do not exist. For example:

cd /opt/oracle/instantclient_12_2 ln -s libclntsh.so.12.1 libclntsh.so ln -s libocci.so.12.1 libocci.so

Install the libaio package. This is called libaio1 on some Linux distributions.

For example, on Oracle Linux, run:

sudo yum install libaio

If Instant Client is the only Oracle software installed on this system then update the runtime link path, for example:

sudo sh -c "echo /opt/oracle/instantclient_19_3 > \ /etc/ld.so.conf.d/oracle-instantclient.conf" sudo ldconfig

Alternatively, set the LD_LIBRARY_PATH environment variable prior to running applications. For example:

export LD_LIBRARY_PATH=/opt/oracle/instantclient_19_3:$LD_LIBRARY_PATH

The variable can optionally be added to configuration files such as ~/.bash_profile and to application configuration files such as /etc/sysconfig/httpd.

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 network/admin subdirectory. This needs to be created for 12.2 and earlier, for example:

mkdir -p /opt/oracle/instantclient_12_2/network/admin

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

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

To use binaries such as sqlplus from the SQL*Plus package, unzip the package to the same directory as the Basic package and then update your PATH environment variable, for example:

export PATH=/opt/oracle/instantclient_19_3:$PATH

Start your application.

Installation of RPM files:

Download the desired Instant Client RPM packages. All installations require a Basic or Basic Light RPM.
Install the packages with yum. For example:

sudo yum oracle-instantclient19.3-basic-19.3.0.0.0-1.i386.rpm

Note that from 19.3, by default only one version of the Instant Client RPM libraries can be installed at a time.

Prior to 19.3, if Instant Client is the only Oracle software installed on this system then update the runtime link path, for example:

sudo sh -c "echo /usr/lib/oracle/18.3/client/lib > \ /etc/ld.so.conf.d/oracle-instantclient.conf" sudo ldconfig

For Instant Client 19.3 RPM packages, these commands are automatically run.

Alternatively, set the LD_LIBRARY_PATH environment variable prior to running applications. For example:

export LD_LIBRARY_PATH=/usr/lib/oracle/18.3/client/lib:$LD_LIBRARY_PATH

The variable can optionally be added to configuration files such as ~/.bash_profile and to application configuration files such as /etc/sysconfig/httpd.

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 network/admin subdirectory under lib/. This needs to be created for 12.2 and earlier, for example:

sudo mkdir -p /usr/lib/oracle/12.2/client/lib/network/admin

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

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

To use binaries from the tools package, use yum to install the package and then update your PATH environment variable, for example:

export PATH=/usr/lib/oracle/19.3/client/bin:$PATH

Start your application.
