[omniORB] Counterpart of COM's AddRef

[Bo Zou]

As a beginner for CORBA, I wonder if there are counterparts for COM/DCOM's
AddRef() and Release() in omniORB? 
We want to convert our application from COM to CORBA, but till now I have
not found how to control the lifecycle of an object in server by clients.
The omniORB's lifecycle support does not seem to target at this issue.
What I want is when no client (colate or out of process) use a object again,
this object should be disposed automatically and transparently in the
server.

Thanks for any help in advance.
