Sample Provider Programs
The sample provider programs are located in subdirectories of /usr/demo/wbem/provider, and are
described in the following table.
Table 3-2 Sample Provider Programs
Top-level provider program that fulfills requests from
the CIM Object Manager and routes these requests to the Native_Example provider.
This program implements the instanceProvider and methodProvider APIs. This program also declares
methods to enumerate instances and to get an instance of the Native_Example
class. This program also declares a method that invokes a method to
print the string “Hello World.”
Creates a class that registers the NativeProvider provider
with the CIM Object Manager. This MOF file identifies NativeProvider as the
provider to service requests for dynamic data in the Native_Example class. The
file also declares the properties and methods to be implemented by the
The NativeProvider program calls this provider to enumerate instances and to get
an instance of the Native_Example class. The Native_Example provider uses the APIs
to enumerate objects and to create instances of objects. The Native_Example class
declares native methods, which call C functions in the native.c file to
get system-specific values. Examples of such values include host name, serial number,
release, machine, architecture, and manufacturer.
This C program implements methods in the Native_Example
Java provider in native C code.
A machine-generated header file for the Native_Example
class. Defines the correspondence between the names of native method in the
Java programming language and the native C functions that execute those methods.
native C code compiled from the native.c file.
How to Run the Sample Provider Programs
You must set up your environment before you can run the sample
- Set the LD_LIBRARY_PATH environment variable to the location of the provider class
To use the C shell, type:
% setenv LD_LIBRARY_PATH /usr/sadm/lib/wbem
To use the Bourne shell, type:
% LD_LIBRARY_PATH = /usr/sadm/lib/wbem
- Copy the libnative.so shared library file to the directory specified by the
LD_LIBRARY_PATH environment variable.
% cp libnative.so /usr/sadm/lib/wbem
- Move the provider class files to the same path as the package
to which those files belong.
% mv *.class /usr/sadm/lib/wbem
- Become root superuser.
- Stop the CIM Object Manager in the same shell in which you
set the LD_LIBRARY_PATH environment variable.
# /etc/init.d/init.wbem stop
Note - When you set the LD_LIBRARY_PATH environment variable in a shell, you must
stop and restart the CIMOM in the same shell to recognize the
- Start the CIM Object Manager.
# /etc/init.d/init.wbem start
- Exit being superuser.
- Compile the program's associated .mof file to load the appropriate class in
the CIMOM and to identify the provider.
% mofcomp -u root -p root-password Native_Example.mof
- Start CIM Workshop.
- In the CIM Workshop toolbar, click the Find Class icon.
- In the Input dialog box, type the name of the class that
you want to display and then click OK.
The class displays in CIM Workshop.
