Pipeline configuration files
The configuration of a pipeline used to handle a web service request is specified in an XML document, known as a pipeline configuration file.
The pipeline configuration file is stored in the z/OS® UNIX System Services file system and its name is specified in the CONFIGFILE attribute of a PIPELINE resource definition. Use a suitable XML editor or text editor to work with your pipeline configuration files. The XML schemas for the pipeline configuration files are in the directory /usr/lpp/cicsts/cicsts52/schemas/pipeline/ (where /usr/lpp/cicsts/cicsts52 is the default install directory for CICS files on CICS® UNIX). When you work with configuration files, ensure that the character set encoding is UTF-8. If you import an existing configuration file that is encoded in EBCDIC, it is automatically converted to UTF-8.
Pipeline | Schema | Root element |
---|---|---|
Service provider | Provider.xsd |
<provider_pipeline> |
Service requester | Requester.xsd |
<requester_pipeline> |
<provider_pipeline>
and <requester_pipeline>
elements have the following immediate sub-elements:- A
<service>
element, which specifies the message handlers that are invoked for every request. This element is mandatory when used within the<provider_pipeline>
element, and optional within the<requester_pipeline>
element. - An optional
<transport>
element, which specifies message handlers that are selected at run time, based upon the resources that are being used for the message transport. - For the
<provider_pipeline>
only, an optional<apphandler>
element, which is used to specify channel-attached application handlers. - For the
<provider_pipeline>
only, an optional<apphandler_class>
element, which is used to specify an Axis2 application handler. - An optional
<service_parameter_list>
element, which contains the parameters that are available to the message handlers in the pipeline.
Associated with the pipeline configuration file is a PIPELINE resource. The attributes include CONFIGFILE, which specifies the name of the pipeline configuration file in z/OS UNIX. When you install a PIPELINE definition, CICS reads the information that it needs in order to configure the pipeline from the file.

Example provider pipeline configuration file (JSON application handler)
This is a simple example of a configuration file for a service provider pipeline that uses the<cics_json_handler_java>
element: <p><?xml version="1.0" encoding="EBCDIC-CP-US"?>
<provider_pipeline xmlns="https://www.ibm.com//software/htp/cics/pipeline">

</provider_pipeline>
The pipeline contains just one
message handler. The handler links to program DFHJSON.- The
<provider_pipeline>
element is the root element of the pipeline configuration file for a service provider pipeline. - The
<service>
element specifies the message handlers that are invoked for every request. In the example, there is just one message handler. - The
<terminal_handler>
element contains the definition of the terminal message handler of the pipeline. - The
<cics_json_handler_java>
element indicates that the pipeline is a Java-based pipeline and the service handler of the pipeline is a message handler that supports JSON messages. - The
<apphandler>
element specifies the name of the application handler that the terminal handler of the pipeline links to by default. In this case, the program is DFHJSON, which is the CICS-supplied program for applications deployed with the CICS JSON assistant.
