Running the Image Copy function with DFSUDMP0 JCL

You can run the Image Copy function of IMS HP Image Copy to create image copies by using a JCL stream that is coded for the DFSUDMP0 program.

About this task

There are two ways to invoke the DFSUDMP0 program:

Invoke the stand-alone DFSUDMP0 by specifying EXEC DFSUDMP0

If you want to use one of the following functions with IMS compatible JCL, use the stand-alone DFSUDMP0.

• Create a concurrent image copy (CIC)
• Use High Performance Input/Output interface (HPIO)
• Invoke the IMS HP Image Copy compression routine in zIIP processor

Invoke DFSUDMP0 by using the IMS Region Controller program (DFSRRC00)

If you want to enable the single-step HASH Check option for HALDBs, invoke DFSUDMP0 by using the IMS Region Controller program (DFSRRC00).
