9.2.6 Phase 5 - Merge VSAM Information into VOA

In this phase, the information on VSAM data sets that was
consolidated into the _VS file is now used to update the
Volume Activity (VOA) file.  Each VSAM observation has its
data summed into the statistics for a given volume.  If any
VSAM records are detected for a volume that is not in the
work VOA file created in Phase 1 processing, the VSAM/Volume
Exception Report is written to the MICSLOG Sysout Data Set.

For each observation that will be written to the output VOA
file, the user exit, USRSVOA, is invoked.  The final
processing in this phase re-sorts the VOA file into its final
order, and writes it to the CA MICS database.
