By default, the Notifier uses ianywhere.ml.script.ServerContext to connect to the consolidated database. This means that it uses the connection string that was specified in the current mlsrv10 session's command line.
This is an optional property that can be used to override the default connection behavior. You can use it to connect to any database, including the consolidated database. It may be useful to connect to another database when you want notification logic and data to be separate from your synchronization data. Most deployments will not set this property.
See ServerContext interface.
