You can access and edit existing data sets within an enterprise server region using Data File Editor. 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.
Opening and editing a data set from Data File Editor is subject to the same permissions checks as you would expect if you were connecting directly to the enterprise server region. Further security measures are also taken, such as removing the full pathname of a data set from the File Information tab and the list of recent files.
If an external security manager is in place, you must enter valid logon credentials when attempting to open the data set. When opening and closing a data set, the ENQ and DEQ locking mechanisms are applied accordingly, and if the Audit Manager is running, file operations are recorded in the audit trails.
Data sets will usually be opened through a Fileshare server running in the region that you connect to. Although, this does not have to be the case if you are opening data sets on a local region, as you can bypass Fileshare and open them directly, which can give faster access. In fact, in this scenario Fileshare does not even need to be configured.
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 Editor cannot auto-select a structure file of the same name and same location if you are connecting to a remote machine; you must select one each time you open the data set.
