Defined DSNM SPI Components

Scope of This Appendix

Internally, DSNM uses the Tandem Subsystem Programmatic Interface (SPI) for

command and response message flows. DSNM SPI components (constants and data

definitions) are defined in the DSNM SPI Data Definition Language (DDL) and may be

identified by the prefix ZDSN^.

SPI messages are handled by the frame and are generally hidden from the user-written

command thread, but certain SPI DDL constants and structure definitions are required.

This appendix lists the SPI DDL constants and structure definitions that user-written

procedures must use.

Commands

The following action codes identify the DSNM commands:

ZDSN^ACTION^ABORT

ZDSN^ACTION^AGGREGATE

ZDSN^ACTION^INFO

ZDSN^ACTION^START

ZDSN^ACTION^STATISTICS

ZDSN^ACTION^STATUS

ZDSN^ACTION^STOP

Modifiers

The following structure definition defines the modifiers in a DSNM command.

STRUCT ZDSN^DDL^MOD^DEF contains the following fields of interest:

INT Z^AMOD

INT Z^EMOD

INT Z^HMOD

INT Z^RMOD

INT Z^SMOD

HMOD Values

The following constants are the possible Z^HMOD values:

Zero (omitted)—Default to ZDSN^HMOD^ALL

ZDSN^HMOD^ALL

ZDSN^HMOD^ONLY

ZDSN^HMOD^SUBONLY
