Module Management

Modules are parts of a business model that are either used to create model instances or are imported and used by other modules: they constitute a logical part of the model providing resources, related data structures, etc. used by other modules.

Modules are created in PDS. Once ready, you can upload them to an LSPS Server using one of the management tools. On upload, a module with all its module imports is uploaded to the Module Repository of the LSPS Server. Management tools allow you to manage the modules in the Module Repository: apart from uploading of modules, you can download and delete them.

Module List

When working with modules, the following properties are available to the management tools:

• Name: arbitrary name as specified in module properties
• Version: version as specified in module properties
• Executable: whether the module can be used to create model instances
• Upload date: time when the module was uploaded
• Unfinished instances: number of unfinished (running and suspended) model instances based on the module (only on executable modules)
• Hash: hash code counted based on the content and properties of the module
• Id: id of the module unique on the server

Listing Modules in the Management Perspective

To list the modules uploaded on an LSPS Server in the Management Perspective, connect PDS to the LSPS Server and open the Management perspective: the list of modules is available in the Module Management view.

If the view is not displayed, go to Window > Show View > Module Management

Listing Modules in Management Console

To list the modules uploaded on an LSPS Server in Management Console, log in to the console and open the Modules page.

Listing Modules from the Command Line

To list the modules on the LSPS Server from the Command Line, use the modelList command.

Module Upload

When uploading a module to the Module Repository so it can be used by model instances, you need to define how to deal with any database changes the module might be introducing. The behavior is is set by the database update strategy:

• Do not change: Existing schema remains unchanged.
• Update by model: New tables, columns and relationships are added; no data is deleted.
• Validate: Existing schema is validated against the new model schema (if inconsistencies are detected, the model launching fails).
• Drop and create modeled DB tables: Existing schema is dropped and a new schema following the new model definitions is created.

If the database already contains data in the pertinent tables and you want to upgrade the schema to match the schema of new versions of the modules, first generate the schema update scripts, modify the scripts to migrate the schema with your business data before you upload the modules.

Uploading a Module from the Management Perspective

To upload a module from your workspace or a module zip file using the Management perspective of your PDS, do the following:

1. Make sure your PDS is connected to the correct LSPS server.
2. In the Module Management view, click the Upload button.
3. In the Module Upload dialog, define the upload details:
   1. Select either a zip file with an exported module on your filesystem or a module from your workspace.
   2. Define the database update strategy.
   3. Unselect the Do not execute schema update scripts flag.
4. Click OK.

Generating Schema Update Scripts

When upgrading the data model of your model to a version which is not backward compatible and you want to migrate the existing data or migrate the underlying database schema manually, generate the schema update scripts for your models, modify them as required and apply them on the database.

To generate the schema update scripts for your modules do the following:

1. Open PDS and connect to the LSPS Server with the current modules.
2. Switch to the Management perspective.
3. In the Module Management view, click the Upload button.
4. In the Module Upload dialog, define the details:
   1. Select either a zip files with the new modules or modules from your workspace.
   2. Set Database Schema Strategy: Set Update by model to generate scripts that will update the current schema or Drop and Create Modeled DB Tables to generate scripts that will create the new schema from scratch.
   3. Select the Do not execute DB scripts scripts flag: This prevent the schema update scripts execution and makes the scripts available in the tab Schema Update Scripts. You can find details such as lists of problems and conflicts discovered in the current schema in the script details.
5. Adapt the scripts as necessary:
   • Include the data stored in the tables of the old schemaUpdateScripts
   • Do not remove any tables or columns used by either the new or old models if their instances will be updated as part of migration (the new and old schema must be backward-compatible).

Uploading a Module from Management Console

Important: You can upload only Modules exported with the GO-BPMN export.

To upload a Module or a Model to the LSPS Server, do the following:

1. In the Modules view, click the Upload button.
2. Define the database update strategy.
3. In the Model Upload dialog box, locate and select the model, and click Upload.
4. Click the Upload button.

Uploading a Module from the Command Line

To upload a module from the Command Line, use the modelUpload Command over a module zip file; the zip file must be created with GO-BPMN Export.

Important: You can upload only Modules exported with the GO-BPMN export.
