The node-oracledb add-on for Node.js powers high performance Oracle Database applications.
The steps below create a Node.js installation for testing. Adjust the steps for your environment.
This node-oracledb release has been tested with Node 0.10, 0.12, 4.2 LTS and 5 on 64-bit Oracle Linux and Windows. The add-on can also build in some Mac OS X, 32-bit Linux, 32-bit Windows, Solaris and AIX environments, but these architectures have not been fully tested.
Installation requires Oracle 11.2 or 12.1 client libraries. These are included in Oracle Instant Client RPMs or ZIPs, a full Oracle Client, or a database on the same machine. Oracle's standard client-server network compatibility applies. For example, with Oracle Client 12.1 you can connect to Oracle Database 10.2 or greater. Use Oracle Client 11.2 if you need to connect to Oracle Database 9.2.
A compiler is required. Use Visual Studio on Windows, gcc on Linux or Xcode on OS X. When building with Node 4 onwards, the compiler must support C++11. Note the default compiler on Oracle Linux 6 and RHEL 6 does not have the required support. Install a newer compiler or upgrade to Oracle Linux 7.
Python 2.7 is needed by node-gyp. If another version of Python occurs
first in your binary path then, when you install node-oracledb, use
the --python option to indicate the correct version. For example:
npm install --python=/whereever/python-2.7/bin/python oracledb.
Instructions may need to be adjusted for your platform and environment.

Node-oracledb can be installed on the pre-built Database App Development VM for VirtualBox, which has Oracle Database 12c pre-installed on Oracle Linux. If you want to install your own database, installing the free Oracle Database 11.2 'XE' Express Edition is quick and easy. Other database editions may be downloaded here. If you want to install Oracle Linux yourself, it is free from here.
Download the
Node.js Linux 64-bit binaries and
extract the file, for example into /opt:
cd /opt
tar -Jxf node-v4.2.3-linux-x64.tar.xz
Set PATH to include Node.js:
export PATH=/opt/node-v4.2.3-linux-x64/bin:$PATH
Download the free Basic and SDK RPMs from Oracle Technology Network and install them as the root user:
rpm -ivh oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
rpm -ivh oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm
If you have a ULN subscription, you can
alternatively use yum to install these packages from the
Oracle Software for Oracle Linux channel for your version of Linux.
If you are behind a firewall you may need to set your proxy, for example:
export http_proxy=http://my-proxy.example.com:80/
or, in csh:
setenv http_proxy http://my-proxy.example.com:80/
Install node-oracledb from the NPM registry:
npm install oracledb
Node-oracledb will automatically be configured to use the highest version
Instant Client RPMs installed. To use a different version, follow the
instructions to
install on Linux with Instant Client ZIP files instead,
setting the install-time variables OCI_LIB_DIR and OCI_INC_DIR to
the appropriate directories.
If you have other Oracle software installed on the same machine, and
the run time linker is configured to find this other software via
LD_LIBRARY_PATH or ldconfig, then update the environment to use
the Instant Client RPM libraries, for example
/usr/lib/oracle/12.1/client64/lib.
Note: A compiler supporting C++11 is required when building with Node.js 4 or later, otherwise the NAN component will fail to build.
Download the example programs from GitHub.
Edit dbconfig.js and set the database credentials to your
environment.
module.exports = {
user : "hr",
password : "welcome",
connectString : "localhost/XE"
};
Run one of the examples:
node select1.js
Download the
Node.js Linux 64-bit binaries and
extract the file, for example into /opt:
cd /opt
tar -Jxf node-v4.2.3-linux-x64.tar.xz
Set PATH to include Node.js:
export PATH=/opt/node-v4.2.3-linux-x64/bin:$PATH
Download the free Basic and SDK ZIPs from Oracle Technology Network and install them into the same directory:
cd /opt/oracle
unzip instantclient-basic-linux.x64-12.1.0.2.0.zip
unzip instantclient-sdk-linux.x64-12.1.0.2.0.zip
mv instantclient_12_1 instantclient
cd instantclient
ln -s libclntsh.so.12.1 libclntsh.so
You will need libaio installed. On some platforms the package is
called libaio1.
To run applications, you will need to set the link path:
export LD_LIBRARY_PATH=/opt/oracle/instantclient:$LD_LIBRARY_PATH
Alternatively, if there is no other Oracle software on the machine
that will be impacted, permanently add Instant Client to the run-time
link path. Do this on Linux by creating a file
/etc/ld.so.conf.d/oracle-instantclient.conf that contains the library
location /opt/oracle/instantclient, and then run ldconfig as
the root user.
Tell the installer where to find Instant Client:
export OCI_LIB_DIR=/opt/oracle/instantclient
export OCI_INC_DIR=/opt/oracle/instantclient/sdk/include
These variables are only needed during installation.
If Instant Client is in /opt/oracle/instantclient and you have no
other Oracle software installed, then these variables are not
actually required. See
Oracle Client Location Heuristic on Linux.
If you are behind a firewall you may need to set your proxy, for example:
export http_proxy=http://my-proxy.example.com:80/
or, in csh:
setenv http_proxy http://my-proxy.example.com:80/
Install node-oracledb from the NPM registry:
npm install oracledb
If you are installing with sudo, you may need to use sudo -E to
preserve the environment variable values.
Note: A compiler supporting C++11 is required when building with Node.js 4 or later, otherwise the NAN component will fail to build.
Download the example programs from GitHub.
Edit dbconfig.js and set the database credentials to your
environment:
module.exports = {
user : "hr",
password : "welcome",
connectString : "localhost/XE"
};
Run one of the examples:
node select1.js
Note: Remember to set LD_LIBRARY_PATH or equivalent first.
The ORACLE_HOME can be either a database home or a full Oracle client installation installed with Oracle's runInstaller.
For easy development, the free Oracle XE version of the database is available on Linux. Applications developed with XE may be immediately used with other editions of the Oracle Database.
Download the
Node.js Linux 64-bit binaries and
extract the file, for example into /opt:
cd /opt
tar -zxf node-v4.2.3-linux-x64.tar.gz
Set your PATH variable to include Node.js:
export PATH=/opt/node-v4.2.3-linux-x64/bin:$PATH
The installer will automatically look for Oracle libraries and headers under
$ORACLE_HOME, see
Oracle Client Location Heuristic on Linux.
However, if you have Instant Client RPMs installed and don't wish the RPMs
to be used, you must explicitly set two environment variables:
export OCI_LIB_DIR=$ORACLE_HOME/lib
export OCI_INC_DIR=$ORACLE_HOME/rdbms/public
These variables are only needed during installation.
If you are behind a firewall you may need to set your proxy, for example:
export http_proxy=http://my-proxy.example.com:80/
or, in csh:
setenv http_proxy http://my-proxy.example.com:80/
Install node-oracledb from the NPM registry:
npm install oracledb
If you are installing with sudo, you may need to use sudo -E to
preserve the environment variable values.
Set LD_LIBRARY_PATH to the Oracle library directory. This variable,
and other variables used by Oracle clients, are typically set in a
shell by executing source /usr/local/bin/oraenv. Or, if you are
using Oracle XE, execute source /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh. The Node.js
process will need access permissions for the Oracle libraries and
other files.
Download the example programs from GitHub.
Edit dbconfig.js and set the database credentials to your
environment:
module.exports = {
user : "hr",
password : "welcome",
connectString : "localhost/XE"
};
Run one of the examples:
node select1.js
Building node-oracledb requires Xcode from the Mac App store.
Download the Node.js package for OS X 64-bit and install it.
Do either of the options given in 5.3.1 or 5.3.2.
This first installation option puts Instant Client in the default location used by the node-oracledb installer. It requires root access. If you don't want to update system directories then follow the alternative steps in 5.3.2.
Download the free Basic and SDK ZIPs from Oracle Technology Network and install them into the same directory:
sudo su -
unzip instantclient-basic-macos.x64-11.2.0.4.0.zip
unzip instantclient-sdk-macos.x64-11.2.0.4.0.zip
mkdir /opt/oracle
mv instantclient_11_2 /opt/oracle/instantclient
ln -s /opt/oracle/instantclient/libclntsh.dylib.11.1 /opt/oracle/instantclient/libclntsh.dylib
Link the OCI libraries into the default library path:
ln -s /opt/oracle/instantclient/{libclntsh.dylib.11.1,libnnz11.dylib,libociei.dylib} /usr/local/lib/
Continue with 5.4.
This is an alternative to 5.3.1 that does not require root access.
Download the free Basic and SDK 64-bit ZIPs from Oracle Technology Network and install them into the same directory:
unzip instantclient-basic-macos.x64-11.2.0.4.0.zip
unzip instantclient-sdk-macos.x64-11.2.0.4.0.zip
cd instantclient_11_2
ln -s libclntsh.dylib.11.1 libclntsh.dylib
Link the OCI libraries into the user default library path:
mkdir ~/lib
ln -s $(pwd)/{libclntsh.dylib,libclntsh.dylib.11.1,libnnz11.dylib,libociei.dylib} ~/lib/
To allow the node-oracledb installer to find the Instant Client
libraries and headers, set the install-time variables OCI_LIB_DIR
and OCI_INC_DIR to the appropriate directories:
export OCI_LIB_DIR=~/lib
export OCI_INC_DIR=~/instantclient_11_2/sdk/include
These variables are only needed during installation.
If you are behind a firewall you may need to set your proxy, for example:
export http_proxy=http://my-proxy.example.com:80/
or, in csh:
setenv http_proxy http://my-proxy.example.com:80/
As a normal user, install node-oracledb from the NPM registry:
npm install oracledb
If you are installing with sudo, you may need to use sudo -E to
preserve the environment variable values.
Download the example programs from GitHub.
Edit dbconfig.js and set the database credentials to your
environment:
module.exports = {
user : "hr",
password : "welcome",
connectString : "localhost/XE"
};
Run one of the examples:
node select1.js
To run a database on OS X, one option is to use VirtualBox, see The Easiest Way to Install Oracle Database on Mac OS X.
Note: An Oracle Technology Network article Installing node-oracledb on Microsoft Windows has step-by-step Windows installation instructions that you can alternatively refer to.
Install a C/C++ build environment such as Microsoft Visual Studio 2012. Compilers supported by Oracle libraries are found in Oracle documentation for each version, for example Oracle Database Client Quick Installation Guide 12c Release 1 (12.1) for Microsoft Windows x64 (64-Bit).
Install the Python 2.7 MSI from www.python.org. Select the customization option to "Add python.exe to Path".
If you use a 32-bit Node.js, make sure to use a 32-bit Oracle client during build and run time. Otherwise use a 64-bit Node.js with a 64-bit Oracle client. The instructions below use a 64-bit stack.
Install the 64-bit Node.js MSI (e.g. node-v4.2.3-x64.msi) from nodejs.org. Make sure the option to add the Node and npm directories to the path is selected.
Building and running node-oracledb needs appropriate Oracle client libraries installed first. These libraries:
- are included in (i) Oracle database, or (ii) in the full Oracle client, or (iii) in Oracle Instant Client. You need one of these.
- must be version 11.2 or greater
- must match the Node.js 32 or 64-bit architecture
If you need appropriate Oracle client libraries, then download the free Instant Client Basic and SDK ZIP files from Oracle Technology Network.
Extract instantclient_basic-windows.x64-12.1.0.2.0.zip and
instantclient_sdk-windows.x64-12.1.0.2.0.zip to the same directory.
Optionally rename the resulting Instant Client directory to the default location used by the node-oracledb installer:
ren C:\instantclient_12_1 C:\oracle\instantclient
Add the directory to PATH. For example on Windows 7, update PATH
in Control Panel -> System -> Advanced System Settings -> Advanced ->
Environment Variables -> System variables -> PATH and add your path,
such as C:\oracle\instantclient.
If you have multiple versions of Oracle libraries installed, make sure the desired version occurs first in the path.
Start Visual Studio and open a Developer Command Prompt within it.
Use set PATH in the shell to confirm the Python, Node.js and Oracle
directories are correctly set. If they are not, then set PATH
manually in the shell, or set it in the System Properties panel and
restart the command shell.
Make sure the Microsoft Visual Studio environment variables are set
appropriately. Use set PATH and verify it contains your Visual
Studio paths. If they are not set, use vcvars64.bat (or vcvars.bat if
you building with 32-bit binaries) to set the environment.
Alternatively you can open the 'Developer Command Prompt for Visual
Studio' which has environment variables already configured.
Tell the installer where to locate the Oracle client libraries and
header files by setting the OCI_LIB_DIR and OCI_INC_DIR variables.
These variables are only needed during installation, not at run time.
Do not add them to PATH.
For Instant Client use:
set OCI_LIB_DIR=C:\oracle\instantclient\sdk\lib\msvc
set OCI_INC_DIR=C:\oracle\instantclient\sdk\include
If you are installing with a local database or the full Oracle client, then locate the Oracle directory and set the node-oracle installer variables similar to:
set OCI_LIB_DIR=C:\oracle\product\12.1.0\dbhome_1\oci\lib\msvc
set OCI_INC_DIR=C:\oracle\product\12.1.0\dbhome_1\oci\include
In this case, also make sure that PATH contains C:\oracle\product\12.1.0\dbhome_1\bin.
If you are behind a firewall you may need to set your proxy, for example:
set http_proxy=http://my-proxy.example.com:80/
Install node-oracledb from the NPM registry:
npm install oracledb
Download the example programs from GitHub.
Edit dbconfig.js and set the database credentials to your
environment:
module.exports = {
user : "hr",
password : "welcome",
connectString : "localhost/XE"
};
Run one of the examples:
node select1.js
Node-oracledb binaries can be copied between compatible Windows systems.
Both computers must also have the same version and architecture of Node.js.
Oracle client libraries of the same architecture and the same version
used for building node-oracledb should be in the destination
computer's PATH.
After node-oracle has been built on the source computer, copy the
node_modules\oracledb directory to the destination computer's
node_module directory.
The destination computer's PATH needs to include Visual Studio
redistributables. If you used Oracle client 11.2 then the Visual
Studio 2005 restributable is required. For Oracle client 12.1, use
the Visual Studio 2010 redistributable.
You can also find out the version required by locating the library
OCI.DLL on the source computer and running:
dumpbin /dependents oci.dll
The version of MSVC*.DLL in the output indicates which
redistributable is required on the destination computer. For example,
if you see MSVCR100.dll then you need the VC++ 10 redistributable.
On Linux, the node-oracledb installer looks for Oracle client libraries and headers in the following search order:
- Using install-time environment variables
$OCI_LIB_DIRand$OCI_INC_DIR - In the highest version Instant Client RPMs installed
- In
$ORACLE_HOME - In
/opt/oracle/instantclient
On Linux, if Instant Client RPMs are auto-detected and used during installation, then the Instant Client library directory is added to the run time library search path via the rpath linker option.
This means that using node-oracledb with Instant Client RPMs does not
require the node-oracledb installation variables OCI_LIB_DIR or
OCI_INC_DIR to be set, and does not require LD_LIBRARY_PATH or
ldconfig configuration for run time. Installation is simply:
rpm -ivh oracle-instantclient12.1-basic-12.1.0.2.0-1.x86_64.rpm
rpm -ivh oracle-instantclient12.1-devel-12.1.0.2.0-1.x86_64.rpm
npm install oracledb
node example.js
If you want to use Instant Client RPMs without using rpath, then set
OCI_LIB_DIR and OCI_INC_DIR prior to installation, for example:
export OCI_LIB_DIR=/usr/lib/oracle/12.1/client64/lib
export OCI_INC_DIR=/usr/include/oracle/12.1/client64
npm install oracledb
unset OCI_LIB_DIR OCI_INC_DIR
export LD_LIBRARY_PATH=/usr/lib/oracle/12.1/client64/lib:$LD_LIBRARY_PATH
node example.js
This is useful if you will need to upgrade Oracle Instant Client RPMs to a new major or minor version (for example from 11.2 to 12.1) without re-installing node-oracledb.
If you are installing with sudo, you may need to use sudo -E to
preserve the environment variable values.
If you want to force using rpath when installing node-oracledb on
Linux, then set the node-oracledb installation variable FORCE_RPATH
to any value. For example:
export OCI_LIB_DIR=/opt/oracle/instantclient
export OCI_INC_DIR=/opt/oracle/instantclient/sdk/include
FORCE_RPATH=1 npm install oracledb
unset OCI_LIB_DIR OCI_INC_DIR
node example.js
