You can access and edit existing data sets within an Enterprise Server region using Data File Tools (Technology Preview). The procedure to open a data set in the Data File Editor is different from opening a data file, but once opened in the editor, edit it in the same way as you would a data file.
Data sets opened in this way use the ENQ and DEQ locking mechanisms.
The Enterprise Server can be hosted locally or remotely. In order for you to connect to a remote Enterprise Server region, you must set the CCITCP2 environment variable to the IP address of the Enterprise Server before you open Data File Tools (Technology Preview).
Data sets will usually be opened through a Fileshare server running in the region; although, if you are opening data sets on a local region you can bypass Fileshare and open them directly, which can give faster access.
To use a structure file with a data set, the structure file must be stored locally, which means that, unlike when opening local data files, Data File Tools (Technology Preview) cannot auto-select a structure file of the same name and same location; you must select one each time you open the data set.
