CA Dynam for VSE User Guide

SORT Considerations
Supplementary message definitions can be specified as follows:
To Issue At Specify
CADD996I message Open Input time OIMSG=msg text
CADD997I message Open Output time OOMSG=msg text
CADD998I message Close Input time CIMSG=msg text
CADD999I message Close Output time COMSG=msg text
Supplementary messages are supported for both CA Dynam/D and CA
Dynam/T users. If a data set contains a supplementary message, the message
will be issued regardless of whether the file is processed as a tape or a disk
file.
Message output can be optionally directed to SYSLST, SYSLOG, or both.
SORT Considerations
Many considerations apply when using CA Dynam/D with sort utility programs
other than CA SORT, CA Sort/Merge software product.
CA SORT is a SORT and MERGE program which completely replaces the IBM
Sort/Merge. CA Dynam/D and CA SORT have been designed to complement
one another. Thus, if your data center uses CA SORT 7.2 or above, CA
Dynam/D provides an interface for it.
CA SORT Interface
The CA Dynam/D interface to CA SORT does all of the following:
• Assigns the appropriate DASD device before open.
• Builds the SORTWKn labels if not specified within the job control.
• Provides the correct block and record size so that the CA Dynam Catalog
and the VTOC for the SORTOUT file are correctly updated.
• Specifies the input file size, if you do not, and passes it to CA SORT
(SIZE=n of SORT control statement).
• Truncates the SORTOUT file; all unused DASD space allocated for this file
is released when the SORTOUT file is closed.
