4.4.5.2.6 Usage Notes

The following information must be given consideration when using this method:

• If the register_callback_port method is not invoked by the joint client/server, the callback port is not registered with the ISH and the server defaults to Asymmetric Outbound IIOP. In this case, you must start the server’s IIOP Listener (ISL) with the -O option. The -O option enables Asymmetric outbound IIOP; otherwise, server-to-client invocations will not be allowed by the ISL/ISH.
• If you are using the OracleWrapper Callbacks API instead of the POA and you want to use bidirectional behavior, you always need to invoke the register_callback_port method, even when you are using a ISH that supports GIOP 1.2.
• If you want to use bidirectional capability for a callback object, you must invoke the register_callback_port method before you pass the callback object reference to the server.
