configuration method
OpenDDS includes a file-based configuration framework for configuring global options as well as options related to specific publishers and subscribers, such as discovery and transport configuration.
OpenDDS also allows configuration via the command line with a limited number of options and a configuration API.
This chapter summarizes the configuration options supported by OpenDDS.
OpenDDS configuration involves three main areas:
- General configuration options - configure the behavior of DCPS entities at a global level. This allows processes deployed separately in a computing environment to share common settings that specify behavior (for example, all readers and writers should use RTPS discovery).
- Discovery Configuration Options - Configure the behavior of the discovery mechanism. OpenDDS supports several methods for discovering and associating authors and readers, see Section 7.3 for details.
- Transport Configuration Options - Configure the Extensible Transport Framework (ETF) that abstracts the transport layer from OpenDDS's DCPS layer. Each pluggable transport can be configured individually.
OpenDDS configuration files are human-readable ini-style text files. Table 7-1 shows a list of the available configuration stanza types as they relate to the OpenDDS zone they configure.
