The callback interface provides mandatory and optional
containers as input to the registered program to create or manage
a resource of a specific type.
CICS initializes the containers when the bundle is deployed
and links to the registered program using a channel called DFHRLVI-V1.
Subtopics
DFHRL-CONTROL container
DFHRL-CONTROL is a container of DATATYPE(CHAR). It contains
the tokens for the bundle and the request to create, enable, disable,
or discard a resource.
DFHRL-DATA container
DFHRL-DATA is a container of DATATYPE(BIT) that contains
the metadata for the user resource. The metadata is taken from the
information provided by the manifest in the bundle.
DFHRL-NAME container
DFHRL-NAME is a container of DATATYPE(CHAR). It contains
a character string that represents the name of the resource in the
deployed bundle.
DFHRL-ROOT container
DFHRL-ROOT is a container of DATATYPE(CHAR). It contains
the fully qualified path in the file system of the bundle directory.
DFHRL-TYPE container
DFHRL-TYPE is a container of DATATYPE(CHAR). It contains
a URI that describes the type of resource that the callback program
can manage in a bundle.
