Migrating to Mosel 5

Xpress Insight 4.50 requires apps which have been compiled using Mosel 5.

Migrate your apps

The Xpress Insight Mosel Reference documentation for the mminsight module is available on your local installation folder <installdir>/docs/insight/mminsight/ or on the FICO website.

If you are upgrading an existing installation of Insight 4.x to Insight 4.50 , your apps will already be available but require updating; move to step 4.
If you have created a new environment and installed Xpress 8.5, you can upload the back-up files of your apps from Insight 4 and then upgrade them. Perform the following steps:
  1. If you wish to back-up of your existing apps, export them using the command line tool.
    • To export a single app: 
      insightcmd export --user <user> --password <password> app <app_name> --force app.insight
    • To export all apps: 
      insightcmd export --user <user> --password <password> app --all --force apps.insight
    Note For more, see Using the insightcmd Command Line Tool on the FICO website.
  2. Upgrade to Xpress Insight 4.50 by following the standard upgrade process described in the Xpress Insight Installation Guide.
  3. If you have installed Xpress Insight 4.50 on an empty development environment, import your backed up repository/apps using the Upload App option on the Xpress Insight 4.50 HOME page.

  4. If you have upgraded an existing Insight installation, your apps will be present but shown as incompatible. Migrate and recompile the source files so each of your apps is able to use Mosel 5, for more see the following section Updating your app to Mosel 5.*

    Xpress Insight 4.50 flags incompatible apps by displaying a red border around the app tile on the home page. These apps require updating to Mosel 5. You will not be able to execute any scenarios until the app has been upgraded.

    Incompatible App indication Incompatible App Message displayed when the cursor is placed over the tile.
  5. Upgrade your apps with the newly compiled source files. The new version of the app should now be marked as compatible and ready for validation. *

    * Perform steps 4 and 5 by loading your app source into Xpress Workbench and connecting to your Xpress Insight 4.50 server.

Updating your app to Mosel 5

Xpress Insight 4.50 requires an app is compiled with Mosel 5 using the dynamic mminsight package provided by Xpress Insight 4.50 .

To do this, make these requisite source code modifications:
  1. Review the major changes described in the previous section, Summary of Changes, and make the requisite source code modifications.
  2. Review the mminsight API changes and make the requisite source code modifications, for more see Replaced mminsight functions.
  3. Review the changes in behavior that Mosel 5 introduces which might impact your app, for more see Logic Changes introduced by Mosel 5.
  4. Build the complete app archive for the new version of the app using Xpress Workbench.
Covered Topics
  • Replaced mminsight Functionality
    It is no longer possible to use a static link to mminsight—the module must be dynamically linked into your app. So, if you currently link to mminsight with the imports keyword, you must change this to uses.
  • Logic Changes introduced by Mosel 5
    The new language features introduced by Mosel 5 are largely incremental to the existing functionality and language syntax. However, a few points may require updates to existing Mosel source code.
  • Recommended changes—migrate to VDL/JS API 4.5
    Xpress Insight 4.50 supports JS API 4.5 and VDL 4.5.
