Use case 1: Model server and MPS

This use case shows how model data can be synced between an MPS instance and a model server. This makes model data, previously accessible only in a running MPS or via files, available through a server.

The synchronization needs to be initialized from MPS using the model-server-sync-plugin.

Instructions

Setup MPS

Execute the following command to set up the MPS project under mps/project-mps-backend. It installs the model-server-sync-plugin and its dependencies.

Command to set up the MPS project
./gradlew mps:project-mps-backend:build

Start a model server

Command to start a model server
docker-compose --profile useCase1 up

This command starts a model server under http://localhost:28101/

Start MPS

Open the mps/project-mps-backend in MPS 2021.2.6.

Connect to the model server

  • In the 'Cloud' tool window, right-click on Cloud and select Add Model Server
