Node.js for Oracle Linux

About Node.js for Oracle Linux

The Node.js repositories contain the latest builds of stable Node.js releases from the community, including node-oracledb. They are provided without support.

Available Node.js Releases

Node.js Version	Oracle Linux Release	Repository/Module:Appstream
v16.x	Oracle Linux 8	nodejs:16
v14.x	Oracle Linux 8	nodejs:14
v12.x	Oracle Linux 8	nodejs:12
v16.x	Oracle Linux 7	ol7_developer_nodejs16
v14.x	Oracle Linux 7	ol7_developer_nodejs14
v12.x	Oracle Linux 7	ol7_developer_nodejs12

Enabling Required Repositories

To configure the yum repositories shown above on your system, install the oracle-nodejs-release-el7 or oracle-nodejs-release-el6 RPM. After installing this RPM, the default enabled repository is that for the latest available Node.js release. To configure the Node.js and the Oracle Instant Client repository:

$ sudo yum install -y oracle-nodejs-release-el7 oracle-release-el7


Installing Node.js on Oracle Linux 7

To install the latest Node.js:

$ sudo yum install nodejs


Updating Node.js on Oracle Linux 7

If you have Node.js installed, and a newer release has been published, make sure you update oracle-nodejs-release-el7 first.

$ sudo yum update oracle-nodejs-release-el7
$ sudo yum update nodejs

Note: if your system has oracle-epel-release-el7 installed or ol7_developer_EPEL among its repo definitions, make sure you disable the EPEL repo while installing or updating nodejs, to avoid installing the wrong package. For example:

$ sudo yum --disablerepo=ol7_developer_EPEL install nodejs


node-oracledb: Connecting Node.js to Oracle Database

The node-oracledb module for Node.js powers high performance Oracle Database applications. Use node-oracledb to connect Node.js applications to Oracle Database. The node-oracledb module is open source and maintained by Oracle. It is stable, well documented, and has a comprehensive test suite.

About Oracle Instant Client

node-oracledb depends on Oracle Instant Client. Starting with Oracle Instant Client 21c, yum/dnf configuration files are delivered via the packages oracle-instantclient-release-el8 and oracle-instantclient-release-el7, respectively. Oracle Instant Client packages up to release 19c are in the ol7_oracle_instantclient and ol8_oracle_instantclient repositories, configured with release packages oracle-release-el7 and oracle-release-el8. Assuming you have enabled the repository for Oracle Instant Client appropriate for your Oracle Linux release, it will be installed as a dependency. More details about Oracle Instant Client on this yum server.

Installing node-oracledb

Each Node.js release has its own repository on Oracle Linux yum server and each of those repositories also contains a corresponding RPM for node-oracledb. These RPMs follow this naming scheme:

node-oracledb-node<node release number>
               

For example, on Oracle Linux 7, the node-oracledb RPM for Node.js 16 is named:

node-oracledb-node16
                

Check the repositories listed under Available Releases to see what RPMs are available.

$ sudo yum install node-oracledb-node16

Note: for Oracle Instant Client releases before 19.x, you must set up the environment so that node-oracledb can find the necessary libraries. For example, for Oracle Instant Client release 18.3:

$ sudo sh -c "echo /usr/lib/oracle/18.3/client64/lib > /etc/ld.so.conf.d/oracle-instantclient.conf"
$ sudo ldconfig

Before you use node-oracledb in a Node.js program, set NODE_PATH so that the node-oracledb module can be found:

$ export NODE_PATH=$(npm root -g)

Installing Node.js on Oracle Linux 8

Oracle Linux 8 introduces DNF as well as the concepts of modules, streams and profiles to allow for the management of different versions of software applications within a single operating system release. For mode details, please refer to the documentation.

To install Node.js 16 on Oracle Linux 8:

$ sudo dnf install @nodejs:16

Installing node-oracledb on Oracle Linux 8

To install node-oracledb on Oracle Linux 8:

$ sudo dnf install oracle-instantclient-release-el8 oraclelinux-developer-release-el8
$ sudo dnf install node-oracledb-node14
$ export NODE_PATH=$(npm root -g)
