The MettleCI Workbench is browser-based application which is served from a lightweight agent that resides on your DataStage development environment’s Engine Tier.

In order to be able to install Workbench, you must be in a terminal session either logged in as root or as a user that can sudo as root.

Pre-install steps if operating workbench with a non-default user

By default, the MettleCI Workbench installer creates a new user called mciworkb (if it doesn’t already exist) and sets its primary group to dstage. All files created during the installation are owned by that user and group.
If your environment requires you to use a different user, do the following:

1. As root, create an environment variable called DM_WORKBENCH_USER and set it to the name of the user you want to use.

Installation / Upgrade

1. Download the latest RPM distributable from the MettleCI software download website. The rest of these instructions assume this is located in your user’s HOME directory (~).

2. From that directory, install the package from the shell of your DataStage Development Engine using Package Manager (RPM) (NOTE: For new installations this will create a user called ‘mciworkb’. A full set of changes that this process performs are listed in the Installation Details section below.)

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

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

3. Request a MettleCI licence from your Data Migrators contact, or request an evaluation licence from the MettleCI software download website. The license will be installed during the first step of the Post Installation wizard process.

4. In previous versions, it was required to copy your MettleCI licence file (which will be emailed to you) into the location: /opt/dm/mci/mettleci.lic. This directory was created for you by the RPM installation process.

5. Start the MettleCI Workbench service using the following command

   $> sudo service dm-mettleci-workbench start
   $> # or for AIX...
   $> mciworkbench.rc start

Verify your install/upgrade

1. Verify your Workbench service is running:

   $> sudo service dm-mettleci-workbench status
   $> # or for AIX...
   $> mciworkbench.rc status

2. Opening the following URL in your browser: http://[SERVER_URL]:8080. and check the build number at the bottom of your Workbench browser screen. This should match the number in the number in the filename of the latest RPM distributable you downloaded and installed. If not, see the troubleshooting article A Workbench update doesn't appear to have installed.

Post-installation

1. Configure your MettleCI environment by opening the following URL in your browser: http://[SERVER_URL]:8080 to start a wizard-based process.

2. Follow the setup wizard to provide the various configuration information MettleCI requires, e.g.

   1. Enter the license key which was requested earlier

   2. DataStage environment details

   3. Git repository details (including SSH public key)

   4. Work item management system details (including SSH public key)

Uninstall Workbench

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

   $> sudo rpm -e dm-mettleci-workbench-x.x-x.noarch

You'll need to use a similar command to uninstall the Unit Test Harness too.

Downgrading Workbench

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

   $> rpm -Uvh --oldpackage dm-mettleci-workbench-x.x-x.noarch.rpm

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