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

You only  need ONE proxy provider, for all the third-party providers, no matter 
how many of them you have.
In fact, if you can't easily change the third party providers to work on 
subclasses, you could also install them to different namespaces, and then 
created your single proxy provider in the correct namespace, that just collects 
them all together.

Hi Paul:
Thank you for your  idea.It is a way to resolve my  problem,but when I have a 
lot of third-party providers,writting proxy providers  will be a big job.

The simple answer is if you want two different c  or java based providers to 
provide information to one or multiple instances of  the same class create a 
proxy provider which gathers information from both and  consolidates it into 
specific instances prior to handing the information off to  open Pegasus or any 
other WBEM server API.
