Installing Node.js on z/OS

Before you install Zowe™, you must install IBM SDK for Node.js on the same z/OS server that hosts the Zowe Application Server. To install Node.js for Zowe, you can follow the steps in this topic or in the IBM SDK for Node.js - z/OS documentation.

Note: If you follow the steps in the Node.js documentation to install Node.js, you do NOT need to install Python, Make, Perl, or C/C++ runtime or compiler, which might be listed as prerequisites there. These software packages are NOT required by Zowe. If you can execute node --version successfully, you have installed the prerequisites required by Zowe.

How to obtain IBM SDK for Node.js - z/OS

You can obtain IBM SDK for Node.js - z/OS for free in one of the following ways:

• Order the SMP/E version through your IBM representative for production use

Installing the PAX evaluation version of Node.js -z/OS

Follow these steps to installing the PAX evaluation version of Node.js - z/OS to run Zowe.

1. Download the pax.Z file from the Download section to a z/OS machine.

2. Extract the pax.Z file inside an installation directory of your choice. For example:

   pax -rf <path_to_pax.Z_file> -x pax

3. Add the full path of your installation directory to your PATH environment variable:

   export PATH=<installation_directory>/bin/:$PATH

4. Run the following command from the command line to verify the installation.

   node --version

   If Node.js is installed correctly, the version of Node.js is displayed.

5. After you install Node.js, set the NODE_HOME environment variable to the directory where Node.js is installed. For example, NODE_HOME=/proj/mvd/node/installs/node-v6.14.4-os390-s390x.

To troubleshoot or install the SMP/E version of Node.js, see the documentation for IBM SDK for Node.js - z/OS. Remember that the software packages Perl, Ptyhon, Make, or C/C++ runtime or compiler that the Node.js documentation might mention are NOT needed by Zowe.
