5.2.4.1.4 HVTVDA Retrieval Examples

In the examples, a SAS macro variable is used to specify the
DDname part of the CA MICS file name. These macro variables
are a standard part of CA MICS and are available for all
files. The macro variable name has the form &diiit, where d
is the database identifier, iii is the information area
name, and t is the timespan.  For the examples, a database
identifier of P is used.  The identifier is installation
dependent, so you should find out what the identifiers are at
your installation.

1.  Using the most recent DAYS timespan HVTVDA file, display
    the total blocks of data moved between DASD cache and
    z/OS for each cluster, per HOUR.  Display the percent
    buckets for each blocksize range and the estimated
    average blocksize.  Generate a separate page for each
    cluster.
