Starting the DFM environment requires that computer operations run procedures to start APPC/MVS, the APPC/MVS transaction scheduler, and DFM.

APPC/MVS and the transaction scheduler must be started before starting DFM. To automate these procedures at initial program load (IPL), you can add the startup commands to the system PARMLIB member COMMNDxx (for example, SYS1.PARMLIB(COMMNDxx)).
