SPI Programming Considerations for
TMF
Once your subsystem and EMS processes are running and your management
application has established communication with the TMFSERVE process, the main
business of your management application is to format and send commands, decode
responses and act on the results, and interpret event messages and act on their
information.
This section provides some summary information and discusses SPI programming
considerations that are specific to TMF.
This section contains the following topics:

Definition Files on page 3-1

Message Elements for TMF on page 3-3

Using SPI to Build Commands and Decode Responses on page 3-5

Retrieving and Decoding Event Messages on page 3-8

Templates and Labels on page 3-10

Naming Guidelines for Applications on page 3-11
For a complete list of all token codes and token maps specific to TMF, see the
ZTMFDDL file.
Definition Files
The commands, responses, and event messages sent to and received from TMF are
made up of items called tokens. Each token contains a particular piece of information,
such as a command parameter or an item of information about an event. Tokens can
be single values or structures consisting of several values. Some tokens, called header
tokens, are present in every command and response, and/or in every event message.
Tokens and related data items for commands, responses, and event messages must
be declared in your management applications, and HP provides these declarations for
you in definition files. A set of definition files is provided as part of each HP subsystem
that supports DSM, and a few other software components (such as SPI and EMS) also
provide definition files. Each such software component includes definition files for the
TAL, COBOL85, TACL, and DDL languages.
To be able to use the data declarations defined by a particular HP software component,
your application must incorporate the appropriate programming-language definition file
associated with that software component. The declarations in a COBOL85 definition
file are grouped into sections to enable COBOL85 programs to declare multiple copies
