Before installing Zowe, ensure that your environment meets the prerequisites.

Common system requirements#

  • z/OS Version 2.2 or later.

  • IBM z/OS Management Facility (z/OSMF) Version 2.2 or Version 2.3

    z/OSMF is a prerequisite for the Zowe microservices, Zowe Desktop applications, and Zowe CLI. z/OSMF must be installed and running before you use Zowe.

    tip
    • For non-production use of Zowe (such as development, proof-of-concept, demo), you can customize the configuration of z/OSMF to create what is known as "z/OS MF Lite" that simplifies the setup of z/OSMF. As z/OS MF Lite only supports selected REST services (JES, DataSet/File, TSO and Workflow), you will observe considerable improvements in start up time as well as a reduction in the efforts involved in setting up z/OSMF. For information about how to set up z/OSMF Lite, see Configuring z/OSMF Lite (non-production environment)
    • For production use of Zowe, see Configuring z/OSMF.

Zowe Application Framework requirements#

  • Node.js Version 6.14.4.1 or later on the z/OS host where you install the Zowe Application Server

    To install Node.js on z/OS, follow the instructions in Installing Node.js on z/OS.

  • IBM SDK for Java Technology Edition V8 or later

  • 833 MB of HFS file space

  • Supported browsers:

    • Google Chrome V54 or later
    • Mozilla Firefox V44 or later
    • Safari V11 or later
    • Microsoft Edge (Windows 10)

Zowe CLI requirements#

Zowe CLI is supported on platforms where Node.js 8.0 or 10 is available, including Windows, Linux, and Mac operating systems.

  • Node.js V8.0 or later on your computer

    Tip: You might need to restart the command prompt after installing Node.js. Issue the command node --version to verify that Node.js is installed. As a best practice, we recommend that you update Node.js regularly to the latest Long Term Support (LTS) version.

  • Node Package Manager V5.0 or later on your computer.

    npm is included with the Node.js installation. Issue the command npm --version to verify that npm is installed.

Free disk space#

Zowe CLI requires approximately 100 MB of free disk space. The actual quantity of free disk space consumed might vary depending on the operating system where you install Zowe CLI.
