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

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?

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
