CA Dynam for VSE User Guide

Chapter 2: Maintaining Tape Files
CA Dynam/T is a software system providing tape data set management for
IBM and compatible mainframe computers operating under all releases of VSE
currently supported by IBM. This chapter addresses the basic components of
CA Dynam/T. For information about using the utilities that support tape
management, see the chapter “Supporting Tape File Management.”
Preparing for CA Dynam/T
Audit Data Set
The CA Dynam Audit facility records information concerning the following:
• Every OPEN or CLOSE tape
• Every modification to the Catalog
• Audit information requested by CA Dynam/FI and CA Dynam/D (if installed
with audit support)
Defining the Audit Data Set
After you have selected the Audit option, you must first define and format the
CA Dynam Audit Data Set (audit trail). The Audit facility is shared by all
components of CA Dynam; therefore, you have to submit only one label and
initialize it only once.
Use the file name CAIAUDT to define the Audit Data Set. The system accesses
the data set using direct physical IOCS. However, define it as an SD file for
label purposes.
Locating the Audit Data Set
Review the Audit Trail Facility chapter before determining the location and size
of the data set.
Place the data set on a different disk volume from the Catalog file; if a
hardware failure destroys the Catalog, the Audit data set will still be available
for recovery.
For information about labeling the Audit data set, see the Programming Guide.
