TODO: Martin Walk or TUBerlin provide details on the infrastructure behind https://depositonce.tu-berlin.de,  especially in terms of the Node.js setup/configuration and setup/configuration of proxies.

Our servers run at the university's IT department in an Open Stack environment with these specs:

 This is our PM2 configuration file:

{
  "apps": [
    {
      "name": "dspace-ui",
      "cwd": "/srv/dspace-ui-deploy",
      "script": "dist/server/main.js",
      "node_args": "--max_old_space_size=8192",
      "env": {
        "NODE_ENV": "production",
        "DSPACE_REST_SSL": "true",
        "DSPACE_REST_HOST": "api-depositonce.tu-berlin.de",
        "DSPACE_REST_PORT": "443",
        "DSPACE_REST_NAMESPACE": "/server"
      }
    }
  ]
}

The frontend runs behind an Apache proxy, as described in the Installing DSpace page.

The backend also runs behind an Apache proxy, as described in the Installing DSpace page. I increased the Java memory significantly:

Environment="JAVA_OPTS=-Djava.awt.headless=true -Xmx8G -Xms2G -Dfile.encoding=UTF-8"
