CA Dynam for VSE User Guide

Common Subset Features
Instructions for creating the Catalog and Audit Trail files are included in the
"Maintaining Tape Files" chapter of this guide. For more information about
Catalog and Audit Trail files, see the chapters "Accessing The Catalog" and
“Maintaining and Reporting On The Audit Trail.”
While the Audit Trail and Catalog files are optional features of CA Dynam/D
and CA Dynam/FI, their use provides for more effective management of your
data center's files.
Data Set Control
The CA Dynam Catalog is a common file shared by the three subset systems.
This disk file records information about every file controlled by CA Dynam in
much the same way a card catalog stores data about all the books in a library.
While your production jobs are running, CA Dynam automatically catalogs
pertinent data for each file that is opened or closed, including the following
details:
• Volume serial number
• Data set name and characteristics
• Retention and location information
To ensure that this information is always current and accurate, CA Dynam is
constantly updating the Catalog. You can also update the Catalog manually
from the online screen transactions (CUI File Management) or from the batch
functions (DYNCAT) provided by CA Dynam.
Backup, Restore, and Recover
The CA Dynam Audit Trail file, stored on disk, provides a simple and efficient
means of protecting your data sets in the event of disaster. In addition to
logging data about production job files, it writes an Audit Trail record each
time the CA Dynam Catalog is updated from batch or online processing.
Whenever the need arises, you can backup, restore, and recover the CA
Dynam Catalog from the Audit Trail records.
Report on the Catalog
A common reporting facility, DYNPRINT, enables you to report on the CA
Dynam Catalog and disk VTOCs. It is the CA Dynam family's reporting tool
that lets you generate standard and customized reports using a subset of CA
Earl.
