[openorb-users] How to activate/deactivate a servant into/from memory ?

[Wang, T. <Ton...@ar...>]

Hi All,

I am using OpenORB 1.4 to develop a CORBA application. I would like to limit the number of servants, say 10K, in memory. How do I do it with OpenORB?

Here are two options I have thought of.

One is:


1.       Implement a concrete class MyActivator from ServantActivator and register that class into POA.
public void set_servant_manager( ServantManager imgr )

2.       Then inside MyActivator's
public Servant incarnate(byte[] oid, POA adapter)
method I recreate the servant from DB and populate it into adapter.

The other one is:

3.       Implement a concrete class MyInterceptor from ServerRequestInterceptor.

4.       The inside the overridden
public void receive_request_service_contexts(ServerRequestInfo ri)
method I look up the object_id from ri from AOM and recreate the servant and populate into AOM.

Do you have any advice on how to activate/deactivate servant into/from memory in general?

Thanks,
Tony
