Re: Re: RE: Can I regist two instance providers for a same CIM class?

Why not alter the existing providers to be for CIM_AlertIndications_Kill and 
CIM_AlertIndications_Over90?
Then you can have one provider for CIM_AlertIndications that collects and 
publishes all of them.

Hi Augustin :
Thank you for reply.My problem  is,I'm using exsiting providers.For example,a 
provider implementing CMPI  interface,it generates  CIM_AlertIndications when a 
process is killed.  And another provider implementing C++ interface,it also 
generates  CIM_AlertIndications when CPU load is over 90%. Now I want to get  
indications on both situation. That's why I want to regist two providers  for 
the same CIM class.
 
Here's a part of an example  registration file of sfcb:
ClassName              Namespace    ProviderName                            ProviderLibName                           ProviderType

CIM_InstModification root/cimv2 OSBase_OperatingSystemProvider cmpiOSBase_OperatingSystemProvider indication
 
 
And here's part of log file of  OpenWBEM:
[47992864481616]Registering provider c++::NovellHMS for cim_instcreation/*
[47992864481616]Registering provider c++::omc_linux_process for cim_instcreation/*

Hi  Huruifeng,

It does not matter what kind of provider you might want to try  having 2 of, it 
won't work.
If it could, it would be ambiguous.
When you  register the 2nd provider, for the same purpose, it will over write 
the  first.
I am not familiar with Small Footprint CIM Broker (SFCB), but it would make no 
sense for it  allow 2 providers for the same class and purpose.
I have not actually tried  to have a separate provider for say instances and 
methods, because there would  be no reason to.
A method provider would also need to know about instances as  well, so it is 
hard to see how it would be useful to separate them.
Nothing  is gained by having more providers than the minimal necessary.
Often it is  easiest to use one provider for many, many classes.
The provider is told what  class it is being queried on, so there is no problem 
having fewer  providers.
Think of each provider as an interface to a database.
You would  not want a provider for each table in a database, but just one for 
the entire  database.
You don't need another provider until you have a different database  to also be 
able to connect to.

Hi Sahana:
Here "two providers" you mean  two instance providers? 
Now I hava two indication  providers for CIM_AlertIndication,can I regist both 
of them like sfcb  does?
And what about a  instance provider and a method provider both for  
CIM_ComputerSystem?
 
Regards

Hi  Huruifeng,
You cannot  register two providers for the same CIM class. But you could 
register one  provider each for the CIM class hierarchy. When you enumerate the 
base class for  example CIM_ManagedElement, instances for CIM_ManagedElement and 
its sub class  like CIM_LogicalElement, CIM_Processor etc, will be returned.
Rgds,
Sahana

Hi:
Can I regist two instance providers for a  same CIM class? 
If it is possible, which  provider will be called when a getInstance request is 
recieved?
