Oracle Instant Client Downloads for Linux x86 (32-bit)
See the Instant Client Home Page for more information about Instant Client.
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.

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_3that is accessible to your application. For example: - Prior to Version 18.3, create the appropriate links for the version of Instant Client, if the links do not exist. For example:
- Install the
libaiopackage. This is calledlibaio1on some Linux distributions. - If Instant Client is the only Oracle software installed on this system then update the runtime link path, for example:
- If you intend to co-locate optional Oracle configuration files such as
tnsnames.ora,sqlnet.ora,ldap.ora, ororaaccess.xmlwith Instant Client, then create anetwork/adminsubdirectory. This needs to be created for 12.2 and earlier, for example: - 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
PATHenvironment variable, for example: - Start your application.
cd /opt/oracle unzip instantclient-basic-linux-19.3.0.0.0dbru.zipcd /opt/oracle/instantclient_12_2 ln -s libclntsh.so.12.1 libclntsh.so ln -s libocci.so.12.1 libocci.soFor example, on Oracle Linux, run:
sudo yum install libaiosudo sh -c "echo /opt/oracle/instantclient_19_3 > \ /etc/ld.so.conf.d/oracle-instantclient.conf" sudo ldconfigAlternatively, set the
LD_LIBRARY_PATHenvironment variable prior to running applications. For example:export LD_LIBRARY_PATH=/opt/oracle/instantclient_19_3:$LD_LIBRARY_PATHThe variable can optionally be added to configuration files such as
~/.bash_profileand to application configuration files such as/etc/sysconfig/httpd.mkdir -p /opt/oracle/instantclient_12_2/network/adminThis is the default Oracle configuration directory for applications linked with this Instant Client.
Alternatively, Oracle configuration files can be put in another, accessible directory. Then set the environment variable
TNS_ADMINto that directory name.export PATH=/opt/oracle/instantclient_19_3:$PATHInstallation 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: - Prior to 19.3, if Instant Client is the only Oracle software installed on this system then update the runtime link path, for example:
- If you intend to co-locate optional Oracle configuration files such as
tnsnames.ora,sqlnet.oraldap.ora, ororaaccess.xmlwith Instant Client, then create anetwork/adminsubdirectory underlib/. This needs to be created for 12.2 and earlier, for example: - To use binaries from the tools package, use
yumto install the package and then update yourPATHenvironment variable, for example: - Start your application.
sudo yum oracle-instantclient19.3-basic-19.3.0.0.0-1.i386.rpmNote that from 19.3, by default only one version of the Instant Client RPM libraries can be installed at a time.
sudo sh -c "echo /usr/lib/oracle/18.3/client/lib > \ /etc/ld.so.conf.d/oracle-instantclient.conf" sudo ldconfigFor Instant Client 19.3 RPM packages, these commands are automatically run.
Alternatively, set the
LD_LIBRARY_PATHenvironment variable prior to running applications. For example:export LD_LIBRARY_PATH=/usr/lib/oracle/18.3/client/lib:$LD_LIBRARY_PATHThe variable can optionally be added to configuration files such as
~/.bash_profileand to application configuration files such as/etc/sysconfig/httpd.sudo mkdir -p /usr/lib/oracle/12.2/client/lib/network/adminThis is the default Oracle configuration directory for applications linked with this Instant Client.
Alternatively, Oracle configuration files can be put in another, accessible directory. Then set the environment variable
TNS_ADMINto that directory name.export PATH=/usr/lib/oracle/19.3/client/bin:$PATH
