Re: Execution Error

Hi Manis!

An error as: "Provider
is not a CMPI style provider. Cannot find ProviderName_Create<mi-type>MI
symbol."

usually is caused by the fact that the
<mi-name> used in your provider is not equal to the value of Name
property in registration mof.

instance of PG_ProviderModule

{

Description = "Skeleton
Provider";

Caption = "Skeleton
Provider";

Name
= "SkeletonProvider";

Vendor = "Manish";

Version = "2.0.0";

InterfaceType =
"CMPI";

InterfaceVersion
= "2.0.0";

Location = "SkeletonProvider";

};

CMPI requires as provider entry point
a function like:

CMPI<mi-type>MI* <mi-name>_Create_<mi-type>MI(

const CMPIBroker*,

const CMPIContext*,
CMPIStatus*);

with <mi-type> being Instance
and <mi-name> being SkeletonProvider in your example. So it would
in your case look like:

CMPIInstanceMI* SkeletonProvider_Create_InstanceMI(const
CMPIBroker* broker, const CMPIContext* context, CMPIStatus* rc);

Alternatively use the C provider
factory macros provided in cmpimacs.h.

@param pfx The prefix for all mandatory association provider functions.

This is a character
string without quotes.

Mandatory functions
are: <pfx>Cleanup, <pfx>EnumInstanceNames,

<pfx>EnumInstances,
<pfx>GetInstance, <pfx>

CreateInstance,
<pfx>SetInstance, <pfx>DeleteInstance and

<pfx>ExecQuery.

@param pn The provider
name under which this provider is registered.

This is a character
string without quotes.

@param broker The name
of the broker variable used by this macro to store

the CMPIBroker
pointer

@param hook A statement
that is executed within <pn>Create_InstanceMI

routine. This enables
you to perform additional initialization functions

and is normally
a function call like furtherInit(broker) or CMNoHook.

Use CMNoHook if
no further intialization is required.

@return The function
table of this instance provider.

CMInstanceMIStub(

Skeleton,

SkeletonProvider,

_broker,

CMNoHook);

which requires a static to hold the
broker and would have the CIM Server call for enumerateInstances in your
provider the following function:

static CMPIBroker * _broker;

CMPIStatus SkeletonEnumInstances(

CMPIInstanceMI
* mi,

CMPIContext
* ctx,

CMPIResult
* rslt,

CMPIObjectPath
* ref,

char
** properties)

Execution Error

----------

HI all,

Please help me to get rid of this error,
I have written a demo instance provider and I have

Successfully compiled the mof file as well
as the registeration mof.

But whenever I fired command to the instance
provider like gi, ei , ni etc.. its show me the error that

CIM_ERR_FAILED: ProviderLoadFailure
: <../../ProviderName.dll>

Provider is not a CMPI style provider.
Cannot find ProviderName_Create<mi-type>MI symbol.

Please give me valuable suggestion to solve
this as well as the reason of occurrence of such type of error.

Thanks and Regards

Manish
