oracle Instant Client install

Installation

See the Instant Client Home Page for more information.

Installation of ZIP files:

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. 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.

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

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

6. Start your application.

rpm -ivh 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

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