Methods of installing Zowe on z/OS

The Zowe z/OS binaries are distributed in the following formats. They contain the same contents but you install them by using different methods. You can choose which method to use depending on your needs.

  • Convenience build

    The Zowe z/OS binaries are packaged as a PAX file. You install this build by running shell script within a Unix System Services (USS) shell.

  • SMP/E build

    The Zowe z/OS binaries are packaged as the following files that you can download. You install this build through SMP/E.

    • A pax.Z file, which contains an archive (compressed copy) of the FMIDs to be installed.
    • A readme file, which contains a sample job to decompress the pax.Z file, transform it into a format that SMP/E can process, and invoke SMP/E to RECEIVE the file.

    Note: The SMP/E build is currently in alpha, which means that it is available for early testing. You can provide any feedback about your experience with Zowe SMP/E as issues in the zowe-install-packaging GitHub repo.

While the procedure to obtain and install the convenience build or SMP/E build are different, the procedure to configure a Zowe runtime are the same irrespective of how the build is obtained and installed.
