Oracle Instant Client is a free Oracle database client. The current version is 22.214.171.124.0, and several versions back to 10.1.0.5 are available.
Download the Oracle Instantclient RPM files from http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html. Everyone needs either "Basic" or "Basic lite", and most users will want "SQL*Plus" and the "SDK".
Convert these .rpm files into .deb packages and install using "alien" ("sudo apt-get install alien" if you don't have it).
- For example, for version 126.96.36.199.0-1 for Linux x86_64 (64-bit):
alien -i oracle-instantclient12.1-basic-188.8.131.52.0-1.x86_64.rpm alien -i oracle-instantclient12.1-sqlplus-184.108.40.206.0-1.x86_64.rpm alien -i oracle-instantclient12.1-devel-220.127.116.11.0-1.x86_64.rpm
- Test your Instantclient install by using "sqlplus" or "sqlplus64" to connect to your database:
If you execute sqlplus and get "sqlplus: command not found", see the section below about adding the ORACLE_HOME variable.
If sqlplus complains of a missing libsqlplus.so file, follow the steps in the section "Integrate Oracle Libraries" below.
If sqlplus complains of a missing libaio.so.1 file, run
sudo apt-get install libaio1
or, if you're installing the 32 bit instant client on 64 bit,
sudo apt-get install libaio1:i386
Integrate Oracle Libraries
If oracle applications, such as sqlplus, are complaining about missing libraries, you can add the Oracle libraries to the LD_LIBRARY_PATH each time it is used:
For example, 12.1 version for Linux x86_64:
or to add it to the system library list create a new file as follows:
sudo vi /etc/ld.so.conf.d/oracle.conf && sudo chmod o+r /etc/ld.so.conf.d/oracle.conf
- and add the oracle library path as the first line. For example,
- Then run ldconfig:
Many Oracle database applications look for Oracle software in the location specified in the environment variable 'ORACLE_HOME'.
Typical workstations will only have one Oracle install, and will want to define this variable in a system-wide location.
sudo sudo vi /etc/profile.d/oracle.sh && sudo chmod o+r /etc/profile.d/oracle.sh
Add the following:
Alternatively, each user can define this in their ~/.bash_profile
Note: From Ubuntu 11.04 (confirmed in 11.04 and 14.04) sqlplus was not recognized as a command unless the following line was also included in the oracle.sh file:
Some packages may look for 'oci.h' in $ORACLE_HOME/include, or in $ORACLE_HOME/rdbms/public
The instant client sometimes places the include files, such as oci.h, in /usr/include/oracle/<version>/client.
Inspect your system by running the following commands
ls $ORACLE_HOME ls -d /usr/include/oracle/*/client*/*
If there is no 'include' directory under ORACLE_HOME, and it is located over in /usr/include/oracle/ , create a symbolic link to assist packages looking for these header files. For example,
sudo ln -s /usr/include/oracle/11.2/client $ORACLE_HOME/include
sudo ln -s /usr/include/oracle/12.1/client64 $ORACLE_HOME/include
And then check it is correct
