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 23 can connect to Oracle Database 19c or later, while Oracle Call Interface 19.3 can connect to Oracle Database 11.2 or later. Some tools may have other restrictions.
Instant Client RPMs are also available from yum.oracle.com for Oracle Linux 8 and Oracle Linux 7. Older RPM packages are available for Oracle Linux 8, Oracle Linux 7 and Oracle Linux 6. More information is on the Instant Client for Oracle Linux page.
Note: The Oracle Instant Client 23ai RPMs will be uploaded in the yum repository in the coming weeks.

For general Instant Client information, see the Home Page.
ODBC users should follow the ODBC Installation Instructions.
The "Database Client Installation Guide for Linux" chapter on Installing Oracle Instant Client is here.
Instant Client RPMs are also available without click-through from yum.oracle.com for Oracle Linux 8 and Oracle Linux 7. Older RPM packages are available for Oracle Linux 8, Oracle Linux 7 and Oracle Linux 6.
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:
/opt/oracle/instantclient_19_3
that is accessible to your application. For example:
cd /opt/oracle
unzip instantclient-basic-linux.x64-19.3.0.0.0dbru.zip
The various packages install into subdirectories of /usr/lib/oracle
, /usr/include/oracle
, and /usr/share/oracle
.
cd /opt/oracle/instantclient_12_2
ln -s libclntsh.so.12.1 libclntsh.so
ln -s libocci.so.12.1 libocci.so
libaio
package. This is called libaio1
on some Linux distributions. On Oracle Linux 8 prior to Instant Client 21 you also need the libnsl package.For example, on Oracle Linux, run:
sudo yum install libaio
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:$LD_LIBRARY_PATH
The variable can optionally be added to configuration files such as ~/.bash_profile
and to application configuration files such as /etc/sysconfig/httpd
.
tnsnames.ora
, sqlnet.ora
, ldap.ora
, or oraaccess.xml
with Instant Client, put them in the network/admin
subdirectory. This needs to be created for 12.2 and earlier, for example: mkdir -p /opt/oracle/instantclient_12_2/network/admin
This is the default Oracle configuration directory for applications linked with this Instant Client.
Alternatively, Oracle configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN
to that directory name.
PATH
environment variable, for example: export PATH=/opt/oracle/instantclient_19_3:$PATH
Installation of RPM files:
yum
. For example: sudo yum install oracle-instantclient19.3-basic-19.3.0.0.0-1.x86_64.rpm
Note 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/client64/lib > \
/etc/ld.so.conf.d/oracle-instantclient.conf"
sudo ldconfig
For Instant Client 19.3 RPM packages, these commands are automatically run.
An alternative to using ldconfig
for older versions, is to set the LD_LIBRARY_PATH
environment variable in each shell prior to running applications. For example:
export LD_LIBRARY_PATH=/usr/lib/oracle/18.3/client64/lib:$LD_LIBRARY_PATH
The variable can optionally be added to configuration files such as ~/.bash_profile
and to application configuration files such as /etc/sysconfig/httpd
.
tnsnames.ora
, sqlnet.ora
ldap.ora
, or oraaccess.xml
with Instant Client, put them in the network/admin
subdirectory. This needs to be created for 12.2 and earlier, for example: sudo mkdir -p /usr/lib/oracle/12.2/client64/lib/network/admin
This is the default Oracle configuration directory for applications linked with this Instant Client.
Alternatively, Oracle configuration files can be put in another, accessible directory. Then set the environment variable TNS_ADMIN
to that directory name.
yum
to install the package and then update your PATH
environment variable, for example: export PATH=/usr/lib/oracle/19.3/client64/bin:$PATH
