7 SPI Tokens
SPI tokens are the smallest accessible units in an SPI message buffer. You can use
token definitions provided by HP, and you can define your own tokens using DDL. HP
supplies standard token definitions in C, COBOL, Pascal (on D-series systems), TACL,
pTAL, and TAL. When you define your own tokens, you first define the tokens with the
DDL statements described in this section and then generate token definitions in a host
language, using the source output commands described in Section 9, DDL Compiler
Commands.
You need the statements described in this section only if you plan to write your own
subsystem using Subsystem Programmatic Interface (SPI) messages in a Distributed
Systems Management (DSM) environment.
If you are writing a management application that communicates with HP subsystems
using SPI messages, you use the token definitions supplied by HP. In such a case, this
section can help you understand the DDL excerpts in the manuals that describe SPI
programmatic interfaces.
This section describes the statements that define token types, token codes, and token
maps. For information about building and using SPI messages, see the Distributed
Name Service (DNS) Management Programming Manual.
