Tuxedo /Q Header Control Information
Control information is used to return /Q message attributes for data sources or to specify /Q message
attributes for data targets.
For Data Targets
For data targets calling Tuxedo /Q, the control information can be used to specify the data format,
service name and /Q message attributes. If the output data stream contains header information, any
values in this control information override any adapter command arguments to the output adapter.
The header information must be present in maps, since it provides the only means of specifying the
format of the output data. In the first output card of maps used with the generic translation server you
must specify the data format and optional service name for the purposes of forwarding.
For Data Sources
For data sources calling a Tuxedo /Q, the control information is included in the data if the Header
adapter command (-HDR) is specified. This data contains attributes of the received message.
Tuxedo /Q Control Information Elements
The following table lists valid Tuxedo /Q message control information elements, whether the control
element is present () when accessing a Tuxedo service or a Tuxedo /Q, and whether the command is
