For DB2 tables with direct access, you can use the job Load Data Store Information from External Interface to load these tables into the Data Manager Knowledge Base (see the section Load Data Store Information From External Interface Job in the chapter Work with Jobs in theFront End Guide).
All the information concerning the structure of the DB2 tables must be in a sequential file that will be processed to find the inventory information needed (see the chapter Load Data Store Information from External Interface Sequential File Job in the Data Model Guide).
For information about the sequential file used as input for the job Load Data Store Information from External Interface, see the chapter Load Sequential File with DB2 Catalog in the Toolkit (z/OS).
