Grassfish backend server services

This article explains the functions of the Grassfish backend server services.

Data Calculator

Data Calculator recalculates the XML playlist files. It registers each relevant modification by a user in IXM One and recalculates the corresponding playlists.

The playlists are saved on the server in the following directory: <Grassfish-RootDir>\data\<customer.id >\playlists

Additionally, Data Calculator calculates modified data like playlists, content files, and data files to be transferred to corresponding players. This information is recorded in the MS SQL database.
