CMPI Provider Test Harness

Chip Vincent, IBM

CMPI is a CIMOM-agnostic provider interface supported across a variety of CIM environments, such as OpenPegasus, SFCB, WBEM Solutions, and WMI+A. The interface is designed to allow one to implement a provider once and deploy it in a variety of operating environments. However, the overall complexity of the CIM stack and the nuances between the implementations (and versions) can make testing the provider extremely difficult and expensive. Testing and troubleshooting is further complicated when providers from multiple vendors must operate within the same CIMOM.

The CMPI Provider Test Harness is a powerful provider test tool and diagnostic. It supports pluggable test cases, call intercepts, and even a variety of CMPI implementations. With this tool, it is possible to script tests to perform 100 percent code coverage of a provider in an OpenPegasus, SFCB, or WMI+A environment BEFORE integrating it with the CIMOM and other providers.

From the provider's perspective, the tool acts just like a CMPI broker. However, it is really a sophisticated wrapper for a real CMPI implementation. The wrapper even supports provider up-calls by re-routing requests to a CIMOM running in a separate process on the same system. This allows one to isolate a provider but still test complex provider-repository or provider-provider relationships.

The tool is still in the early stages of development but will be contributed to the open community once stable.

CMPI Provider Test Harness features overview:

• Scriptable interface
• Provider isolation to expedite troubleshooting and simplify debugging
• Pluggable CMPI implementation wrappers (OpenPegasus, SFCB, WMI+A)
• Pluggable test modules

Python CIM Providers

Bart Whiteley, Novell

This session will discuss recent developments in the Python CIM Provider Interface.  Python providers can now run under any CIMOM that supports CMPI.  The session will present the architecture of the Python provider adapter, Python provider concepts, and concrete examples of Python providers.

Java WBEM API (JSR48)

Jim Davis, WBEM Solutions

The JSR48 API is the standard Java API for developing CIM and WBEM Clients and Providers. The API includes support for the following:

    CIM            - A mapping of the Common Information Model (CIM) Meta Schema to Java.
    WBEM
        Client      - A protocol-neutral mapping of WBEM operations to Java.
        Listeners - A set of classes to listen for Indications.
        Providers - A set of interfaces for developing providers.

This session will describe the architecure and design of the API, describe each of the Interface areas, provide running code examples for clients, listeners, providers and CIM Mappings. The examples will use both CIM-XML and WS-Management.

Best Practices for Writing CMPI Providers

Marek Szermutzky, IBM

The Common Manageability Programming Interface (CMPI) is a standard interface for CIM providers supported by many popular CIM Servers. CMPI is binary compatible which makes development of CIM providers independent from a particular CIM Server implementation.  The presentation will cover the "Do's and Dont's" of writing CMPI providers based on practical experiences and samples. Commonly experienced stumbling stones are described and how those can be circumvented or avoided. Focus will be put on how to write high-performance, reliable and stable CMPI providers.

Testing Providers with PyWBEM

Tim Potter, Hewlett Packard

Testing is a vitally important part of provider development, and has different requirements of a CIM client. This presentation will cover the basics of the PyWBEM Python CIM client interface and follow with some useful techniques for testing providers. An introduction to the asynchronous client interface will also be given.

cmpi-bindings - Compiler-free provider development

Klaus Kämpf, Novell
Bart Whiteley, Novell

For a long time, when developing a CIM provider one had to choose a specific CIMOM and programming language, typically C or C++.
The CMPI programming interface removed the CIMOM limitation, pywbem added Python to the list of implementation languages.

In this presentation we show how to use the SWIG (www.swig.org) code generator to enable developers to write CIM providers in any SWIG supported language. This includes Python, Ruby, C#, Java, Perl, Tcl and many more.

Inova Development Tools

Mike Brasher, Inova Development

Inova Development offers two tools to aid developers in creating providers:

• CIMPLE - Generate providers from the Class mof files that can attached as either Peqasus C++ or CMPI providers with concrete C++ objects
• Konkrete - Generate CMPI providers from the Class mof files that use only the C compiler and that generate type-save concrete CIM interfaces from the MOF definitions.

This presentation will introduce both products and will include both an overview of the technologies and demonstration of the generation of providers with both technologies.
