A tool to display all the objects activated with a POA

• Product Version: VB 6.0 onwards
• Product Component: ORB

Resolution

You will need to use a combination of POA and ServerManager APIs to achieve this requirement.

Firstly, the PortableServer::POA_ptr::find_POA() API helps to get the handle of the POA you are looking for. Then, you will have to use ServerManager functionality(which is a proprietary extension of the ORB's capabilities) to get the objects activated in a POA.

The ServerManager is intended mainly for diagnostic purposes and is how the VisiBroker console functionality is implemented. In the examples directory there is a "ServerManager/basic" example which shows the kind of information that can be queried. Check out the html page describing the example. The server must be started with the following options for the ServerManager functionality to be enabled:

vbroker.orb.enableServerManager=true

vbroker.serverManager.name=<name>

To inspect objects associated with the "RootPOA", you would be looking for a container with a name like "/ORB/RootPOA/ActiveObjectMap". Once you have got hold of the container, you will need to invoke get_all_properties() API on the container handle and loop through it to get all the object Ids activated under "RootPOA".

Then, use the PortableServer::POA_ptr::id_to_reference() to get the object reference and invoke ORB::object_to_string() to get the stringified IOR information of every object reference activated under "RootPOA" or for any other child POAs under "RootPOA".
