CICS VSAM Transparency for z/OS, Version 1.2


The automated mapping facility

When you manually map a data set, you are responsible for creating the DDL, mapping the data set with the ISPF mapping dialogs, and generating the driver modules. Alternate indexes must be mapped manually. All of these actions are performed by the automated mapping facility, including the generation of the DB2® DDL and CICS® VT driver modules for alternate indexes associated with a base cluster. You perform the following steps with the automated mapping facility:
  1. Gather information about the data set or data sets to be mapped.
  2. Select Auto mapping facility from the CICS VT main menu, and the DIM name to be processed using the CICS VT ISPF dialogs.
  3. Specify the copybook you want to use to map this DIM.
  4. Optionally edit the mapping data. For example, you might want to change a DB2 column name or attribute. CICS VT always presents the edit panel if a user action is required; for example, if there are duplicate field names in the copybook. Mapping data is inserted into the CICS VT control tables when editing is complete.
  5. Submit the batch auto mapping generation job. This creates the DB2 objects and generates the drivers.
  6. Perform post auto-mapping tasks.
The rules and detailed information on how to perform these tasks are explained in the following section.
