Begin by selecting the Load from File tab. In Data Express for Distributed Systems, two files can be used as input to the load process. The first file contains information about your tables, columns, and indexes. The second optional file contains information about your data store’s referential integrity.
In Data Express for z/OS, only the file that contains information about your tables, columns, and indexes can be used. For a z/OS Knowledge Base, your referential integrity information gets loaded into the Knowledge Base while executing the Import Classification from Referential Integrity job.
The files used as input by the Distributed Loader are created by the Extension Technology utility: dxegenloadfile. Note that this utility will create both files. So, if you are using Data Express for z/OS, the referential integrity file created is used as input to the Import Classification from Referential Integrity job.
