Before installing MettleCI Command Line Interface you will need to perform a pre-installation Java update to make sure your Java environment is compatible with MettleCI.

These instructions assume you have already sourced a MettleCI license file during the Workbench installation process. Note that the installation of MettleCI Workbench is not a prerequisite to installing the MettleCI Command Line Interface.

Installation

  1. Download the latest MettleCI CLI RPM distributable from the MettleCI software download website.

  2. As per the MettleCI Workbench installation, the DM_WORKBENCH_USER environment variable can be used to set file ownership to a user other than the default mciworkb.

  3. Open a shell and navigate to the location of your install images. Install the mettleCI CLI using Red Hat Package Manager (RPM)

    $> sudo rpm -U dm-mettleci-command-shell-x.x-x.noarch.rpm
$> # or for IBM AIX...
$> sudo rpm -U dm-mettleci-command-shell-x.x-x.noarch.rpm --nodeps --ignoreos

    … where x.x.x is the build version of the workbench you downloaded.

  4. If you are installing the MettleCI CLI alongside the MettleCI Workstation on a DataStage engine tier, you will already have a MettleCI license file which the Command Shell will use without need for configuration.

Linking to your MettleCI License file

By default, the config.properties configuration file refers to the license file location by license.file=../mettleci.lic (the parent directory). Save the license file and update the license.file setting to refer to its location.

If you don’t already have a MettleCI license file, request one from your Data Migrators or IBM representative, as appropriate.

The user that runs the MettleCI Workbench service (defined by the DM_WORKBENCH_USER environment variable - typically set to mciworkb) must have Read/Write (minimum 600) permissions to the MettleCI Workbench license file (mettleci.lic)

Verify your install/upgrade

  1. Verify your MettleCi is running:

    $> mettleci
MettleCI Command Line. Build xxx

mettleci>

Uninstall the Command Line Interface

  1. You can uninstall the MettleCI Workbench package like any other RPM package:

    $> sudo rpm -e dm-mettleci-command-shell

Downgrading Command Line Interface

  1. If something goes wrong and you need to downgrade your version of MettleCI Command Line Interface, without performing an uninstall/reinstall, you can use the following command:

    $> rpm -Uvh --oldpackage dm-mettleci-command-shell-x.x-x.noarch.rpm

    … where x.x.x is the build version of the CLI you want to downgrade to.
