CA Dynam for VSE User Guide

Catalog Support for CA Dynam/FI
The DYNAM/FI installation option CATALOG(YES) instructs CA Dynam/FI to
access the Catalog to obtain information; CATALOG(NO) indicates that no
catalog calls will be made by CA Dynam/FI.
The DYNCAT DEFINE/ALTER operand DYNAMFI=YES allows CA Dynam/FI to
access a particular data set's attributes. Therefore, if you want to exclude a
cataloged data set from CA Dynam/FI processing, use DYNAMFI=NO. If you
want CA Dynam/FI to access catalog information, be sure that both
CATALOG(YES) and DYNAMFI=YES are set.
Maintaining Catalog Information
CA Dynam/FI uses the data set attributes to ensure that new versions of a
data set are created with the desired block size, record format, and so on. The
version attributes are used to properly process existing versions of a data set.
CA Dynam/FI will always access the most current version (version 1) of a data
set unless a CA Dynam/T or /D generation option is specified on the
TLBL/DLBL. In other words, if you want to access catalog information for a
version other than version 1, you must use a CA Dynam/T or /D generation
option on the TLBL/DLBL. For example, the following JCL accesses generation
information for versions 2 of DISK.FILE and TAPE.FILE.
// DLBL DISKIN,'DISK.FILE(G-1)'
// TLBL TAPEIN,'TAPE.FILE.(-1)'
// TLBL TAPEIN,'TAPE.FILE',,,,,2
Version attributes are updated by CA Dynam/FI at output only when requested
by CA SORT.
