4.3.1.6 Specifying Ext. File Update Job Characteristics

This section only applies if you are specifying options for
an external journal file in an external file unit.

To create an external journal file and update the ledger
file, you submit an external journal file update job.  You
must specify two characteristics of the update job using
Option 5 on the Rate Table File Options Menu (MWF;4;2;3;6;5):

 1. Whether duplicate data checking should be performed when
    the external journal file update job runs.

 2. The input DD statement to input your external file.

If you specify duplicate data checking, the same data
checking performed for standard CA MICS files is performed
for your external journal file.  The external journal file
update job checks the ENDTS of each record input against the
timestamp information retained in the unit's checkpoint
file, prefix.MICS.CHECKPT.DATA.  Data that falls within the
range in the checkpoint file is deleted.  You should use
duplicate data checking only if each of your input records
has a unique ENDTS.

The following sections contain a worksheet and example you
can use to specify the characteristics of the update job:
