CA Dynam for VSE User Guide

Chapter 10: Accessing the Catalog
The DYNACC facility provides a general interface to the CA Dynam Catalog.
DYNACC accepts data requests, searches the Catalog, and returns data
suitably formatted for building reports. Conceptually, access may be obtained
to almost every data item in the Catalog apart from internal navigational
pointers.
DYNACC is also used by CA Dynam family reporting components such as
DYNPRINT. DYNACC is the means by which user programs and CA Dynam
reporting programs may obtain read-only access to the CA Dynam Catalog.
DYNACC may be used to access the Catalog and obtain information in either
data set or volume serial number sequence. Additionally, information about
the Catalog itself and about vaults may be retrieved.
DYNACC Version 2 is a major redevelopment in response to user requirements.
It is faster, more reliable, easier to use, and more functional than its
predecessor. On average, most programs using it will achieve runtime
reductions approximating 45 percent, and in some cases substantially more.
Complete compatibility has been maintained with the previous version.
Existing programs will execute unchanged in the CA Dynam r6.0 environment.
If an existing program that executes correctly using the earlier version of
DYNACC is relinked or recompiled, it will continue to function correctly, and no
changes are required unless you wish to benefit from the performance
advantages or functional enhancements realized in Version 2.
Supported Languages
Since DYNACC adheres to standard IBM linkage conventions, calling programs
may be written in any language that generates external program calls in a
manner that complies with these rules. This includes, among others, COBOL,
Assembler, and CA Earl. Copy text defining the DYNACC DYNINFO parameter
list is supplied for these three languages.
Using DYNACC
DYNACC is supplied as a relocatable program text file and is linked with the
calling program. It is designed to be CA Dynam release-independent. It runs in
both the CMS and VSE environments. DYNACC and all its called service
routines are self-relocating, reentrant, and operating system independent.
