"<strong>CA</strong> <strong>Dynam</strong> Report Examples."<br />

The report headings are generally self-explanatory, but note the following:<br />

The version number ascends from 1 (the current version) to steadily higher<br />

numbers (<strong>for</strong> older versions). This count is relative and only encompasses<br />

existing versions, so it does not show any gaps.<br />

For disk files this field is the total number of extents on all volumes. For tape<br />

files it is equal to the number of volumes.<br />

This shows the number of volumes on which the file resides.<br />

The creation date is blank if it was never recorded in the <strong>CA</strong> <strong>Dynam</strong> Catalog.<br />

on the DAYSOLD report, files with blank creation dates are ranked at the top.<br />

The age of a file starts at 1 day on the day it is created, and increases by 1<br />

day every night at midnight. Times are not taken into account.<br />

If the file is considered "permanent", the text --PERM-- is shown. For disk files<br />

this means any date equal to or later than the MANDTE value defined in the<br />

DYNAM/D option record, the normal value being 2099/365. For tape files it is<br />

any date equal to or later than 2099/366.<br />

If the file is not "permanent" but has a value equal to or later than the<br />

appropriate value, the text -RETAIN- is shown. For disk files this is the<br />

AUTODTE value defined in the DYNAM/D option record (normally 2099/364)<br />

and <strong>for</strong> tape files it is 2099/365.<br />

LAST ACCESS DATE/TIME<br />

If the last access date is blank, no access since creation has been recorded.<br />

Such files show zeros <strong>for</strong> the last access time, which can be ignored.<br />

DAYS W/O OPEN<br />

TOTAL OPENS<br />

AVERAGE OPENS<br />

PER DAY<br />

This is calculated the same way as the age of the file (see the CREATION DATE<br />

description), but using the last access date. If there is no last access date, this<br />

field is computed from the creation date.<br />

This figure always includes one open <strong>for</strong> the creation of the file.<br />

This is calculated by dividing the "total opens" by the "days since created" as<br />

described above. Since neither of those figures is ever zero, this item tends<br />

to be quite reliable, with values higher than 1 being very unusual.<br />

Occasionally, <strong>for</strong> often-used files, this figure may be inaccurately low due to<br />

"opens" counter wraparound. Presumably such files will be well-known to<br />

you.<br />
