The control containers are essential to the operation of the pipeline.
Handlers can use the control containers to modify the sequence in which the
handlers are processed.
Container DFHERROR
DFHERROR is a container of DATATYPE(BIT) that is used to convey
information about pipeline errors to other message handlers.
Container DFHFUNCTION
DFHFUNCTION is a container of DATATYPE(CHAR) that contains a 16-character
string that indicates where in a pipeline a program is being invoked.
Container DFHHTTPSTATUS
DFHHTTPSTATUS is a container of DATATYPE(CHAR) that
is used to specify the HTTP status code and status text for a message
produced in the response phase of a service provider pipeline.
Container DFHMEDIATYPE
DFHMEDIATYPE is a container of DATATYPE(CHAR) that
is used to specify the media type for a message produced in the response
phase of a service provider pipeline.
Container DFHNORESPONSE
DFHNORESPONSE is a container of DATATYPE(CHAR) that, in the request
phase of a service requester pipeline, indicates that the service provider
is not expected to return a response.
Container DFHREQUEST
DFHREQUEST is a container of DATATYPE(CHAR) that contains
the request message that is processed in the request phase of a pipeline.
If the message was constructed by a CICS-supplied SOAP message handler, and
has not been changed subsequently, DFHREQUEST contains a complete SOAP envelope
and all its contents in UTF-8 code page.
Container DFHRESPONSE
DFHRESPONSE is a container of DATATYPE(CHAR) that contains
the response message that is processed in the response phase of a pipeline.
