VTMA - dual mode control transaction

The dual mode facility (DMF) causes calls to be processed against a VSAM data set and the migrated data in DB2®. The VTMA transaction controls the DMF. You must specify one of the following parameters with VTMA:

STAT
This shows the status of DMF.
START
This starts DMF.
STOP
This stops DMF.
RESTART
This restarts DMF and is only required when applying software maintenance.

The DMF is explained in full in The dual mode facility (DMF).
