Instant Client Downloads
for Linux x86-64

1. Download the desired Instant Client ZIP files. All installations require the Basic or Basic Lite package. 

2. Unzip the packages into a single directory such as /opt/oracle/instantclient_12_1 that is accessible to your application.

3. Create the appropriate libclntsh.so and libocci.so links for the version of Instant Client. For example:

cd /opt/oracle/instantclient_12_1
ln -s libclntsh.so.12.1 libclntsh.so
ln -s libocci.so.12.1 libocci.so

4. Install the libaio package, for example on Oracle Linux, run this as the root user:

yum install libaio

On some Linux distributions the package is called libaio1.

5. Set the environment variable LD_LIBRARY_PATH to the directory created in Step 2, for example:

export LD_LIBRARY_PATH=/opt/oracle/instantclient_12_1:$LD_LIBRARY_PATH

Alternatively, add this path to an ldconfig configuration file if there is no other Oracle software that will be impacted.

6. To use supplied binaries such as SQL*Plus, update your PATH environment variable, for example:

export PATH=/opt/oracle/instantclient_12_1:$PATH

7. Start your application.

1. Download the desired Instant Client RPM packages. All installations require the Basic or Basic Lite RPM. 

2. As the root user, install the packages with yum. For example:

yum install oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm

3. Set the environment variable LD_LIBRARY_PATH to the appropriate directory for the Instant Client version, for example:

export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib:$LD_LIBRARY_PATH

export PATH=/usr/lib/oracle/12.1/client64/bin:$PATH

5. Start your application.
