Oracle Instant Client is a free Oracle database client. The current version is 11.2.0.1.0, and several versions back to 10.1.0.5 are available.

 

Install RPMs

• Download the Oracle Instantclient RPM files fromhttp://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):

  alien -i oracle-instantclient-basic*.rpm
  alien -i oracle-instantclient-sqlplus*.rpm
  alien -i oracle-instantclient-devel*.rpm

• Test your Instantclient install by using "sqlplus" to connect to your database:

 

sqlplus  username/password@//dbhost:1521/SID

If sqlplus complains of a missing libaio.so.1 file, run 

sudo apt-get install libaio1

If sqlplus complains of a missing libsqlplus.so file, follow the steps in the section "Integrate Oracle Libraries" below.

If you execute sqlplus and get "sqlplus: command not found", see the section below about adding the ORACLE_HOME variable. 

 

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, or to add it to the system library list create a new file as follows:

sudo vi /etc/ld.so.conf.d/oracle.conf

• and add the oracle library path as the first line. For example,

 

/usr/lib/oracle/11.1.0.1/client/lib

• or

 

/usr/lib/oracle/11.2/client/lib/

• Then run ldconfig:

  sudo ldconfig

 

ORACLE_HOME

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 vi /etc/profile.d/oracle.sh

Add the following:

export ORACLE_HOME=/usr/lib/oracle/11.1.0.1/client

or

export ORACLE_HOME=/usr/lib/oracle/11.2/client

Alternatively, each user can define this in their ~/.bash_profile

Note: For 11.04 sqlplus was not recognized as a command unless the following line was also included in the oracle.sh file:

export PATH=$PATH:$ORACLE_HOME/bin

 

SDK fix

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

And then check it is correct

ls $ORACLE_HOME
