CICS VSAM Transparency for z/OS, Version 1.2


No data reengineering

Reengineering does not occur if the field type that you specify in the mapping matches the DB2® column type. For example, no reengineering occurs if a field type of C is mapped to a CHAR column, or a field type of P is mapped to a DEC column.

In VIDKSDS shown in Figure 1, there is no data reengineering for the fields that are not highlighted.

Adjacent fields in a VSAM file that map to adjacent columns in DB2 are built in a single operation in CICS® VT, providing that no data reengineering is required.
