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.
Installation of RPMs:
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 "rpm". For example:
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:$LD_LIBRARY_PATH
Alternatively, add this path to an ldconfig configuration file if there is no other Oracle software that will be impacted.
4. To use supplied binaries such as SQL*Plus, update your PATH environment variable, for example:
export PATH=/usr/lib/oracle/12.1/client64/bin:$PATH
