9.4 Daily Update Physical Structure

$VMCXDEF, which resides in sharedprefix.MICS.SOURCE, contains
the information that controls the processing flow of the VM
and CMS Analyzer Daily Update that is required at the unit
level (see Figure 9-9).  This information is used by BASDAILY
to invoke the appropriate modules for processing, which is
determined based upon parameters contained in VMCOPS.

The Account processing logic modules, VMCACTFI and VMCACTFU,
are invoked when the VM Account data is to be processed in
the unit. The VMCACTST module is invoked when no Account data
is to be processed.

Following the VMCACTxx processing, the Input History Log file
is again renamed and saved so that it is not overwritten by
the VM Monitor processing routines. The VM Monitor Data logic
modules, VMCMXAFI and VMCMXAFU, are invoked when the VM
Monitor Data is to be processed within the unit; otherwise,
VMCMXAST is called after which the Input History Log file
from the VM Account processing step is renamed and saved.

Following the data reduction steps, the saved Input History
Log files are combined and %CKRTN4 is invoked which provides
installation access to the history file information.  The VM
Exception files created in the Account and VM Monitor data
reduction steps are then combined into the VMCVXC File for
later processing by the exception modules in DAY200.
