CA Dynam for VSE User Guide

Preparing for CA Dynam/T
Catalog File
The Catalog file controls the tape library. It is a direct access file shared by all
CA Dynam software components.
The Catalog file stores all information necessary to perform the following
actions:
• Select the correct input tape
• Allocate a valid scratch tape
• Report on controlled tape processing
The Catalog file is also used by the following:
• CA Dynam/D for storing information about the management of disk files
• CA Dynam/FI for storing information about file independence
Defining the Catalog File
Use the file name CAICATL to define the CA Dynam Catalog. The system
directly accesses the Catalog with physical IOCS; however, define the Catalog
as an SD file for label purposes.
Locating the Catalog File
Review the Programming Guide before deciding where to place the Catalog
file, its size, and which logical unit will access it.
Audit and Catalog Data Sets
For more information about the Audit and Catalog files, see the chapters
"Accessing the Catalog" and "Maintaining and Reporting on the Audit Trail."
Establishing Data Sets
The batch program, DYNCAT, and the online program, CUI File Management,,
establish and define to the Catalog those data sets that CA Dynam/T is to
control. You can also define data sets to the Catalog at output OPEN through
use of the optional automatic cataloging facility.
A data set must have a unique name. You can include retention information; a
default can be specified in the DYNAM/T option record.
