CICS VSAM Transparency for z/OS, Version 1.2


Generating CICS VT runtime modules

The Functional overview introduced the two runtime modules used by CICS VT: the DIM and the DDM. These modules are ready to be generated when the mapping of each VSAM data set and its alternate indexes is complete.

The DIM driver is used by CICS VT to understand the relationship between the VSAM record structure and the DB2® row structure. The DDM driver contains the SQL that CICS VT uses to access the migrated data sets in DB2. These modules are generated automatically by the automated mapping facility. When you manually map data sets, you must generate the driver modules using the CICS VT ISPF facility.

Before you generate your first drivers, you should review DB2 considerations and The DDM driver module name.
