Calling the recall exit
Programming Interface Information
Programming Interface Information After the list of candidate volumes has been assembled,
DFSMShsm passes control to the recall installation exit (ARCRDEXT)
if the installation exit is active. DFSMShsm passes the complete list
of eligible volumes, not just the five that it has selected, to the
installation exit. The five volumes that DFSMShsm has selected are
at the top of the list. The installation exit can change the volume
selection so that different volumes are the five volumes at the top
of the list, thereby changing the volumes that DFSMShsm uses for the
recall. Another point of divergence from the processing for SMS-managed
data sets is that control is not passed to the installation exit during
the recall of SMS-managed data sets.
Note: In a common recall queue
environment, the ARCRDEXT exit is invoked by the host that selects
the request for processing.
