Elements of SPI Messages for
DSM/SCM
A DSM/SCM event message is formatted as a special SPI buffer. Event Management
Service (EMS) provides high-level procedures that call SPI procedures to format the
event-message buffer. This buffer consists of tokens representing units of information
that describe the event in a form that can be retrieved programmatically.
This section describes elements of Subsystem Programmatic Interface (SPI) event
messages for DSM/SCM.
Tokens
Tokens are defined using the Data Definition Language (DDL). Once defined, DDL is
used to translate the token definitions to each supported programming language: C,
COBOL, HP Tandem Advanced Command Language (TACL), or Transaction
Application Language (TAL). The token definitions in each language are available to
management applications retrieving DSM/SCM event messages.
DSM/SCM uses SPI tokens (tokens whose names begin with ZSPI-), EMS tokens
(names beginning ZEMS-), and tokens specific to DSM/SCM (names beginning
ZPHI-). The definitions of these tokens are stored in a set of source definition files. SPI
tokens are stored in SPI definition files, EMS tokens in EMS definition files, and
DSM/SCM tokens in DSM/SCM definition files. The particular file that a management
application uses depends on the source language of the application. For more
information about tokens, see the SPI Programming Manual.
