Start of changeCICS VSAM Transparency for z/OS, Version 1.2


DMF for CICS programs

There are two parts to enabling the DMF for CICS® programs.

  1. The original VSAM data set must be defined to CICS file control using a predefined file name. This can be defined as either local or remote.
  2. The DMF must be activated at a CICS system level using the VTMA transaction.

The definition of the data set in the CICS VT data set table (DST) includes two optional parameters relating to DMF: ERRORACT and DUMP. These are discussed in Adding a new data set to the CICS VT data set table.

Output from the DMF is written to the CICS DD statement VIDCOMP.

If you are using MRO and have defined the DMF file as remote, CICS VT assumes that it is always available for processing.
