• Recent versions of RMI-IIOP derive their servants from the standard Servant class.
• Both CORBA and RMI-IIOP utilize the General Inter-ORB Protocol communication standard.
• Also, most modern firewalls support GIOP & IIOP and are thus CORBA-friendly firewalls.
• The package provides the support for the remote communication between applications, using the RMI over IIOP protocol.
• In other words, WSDL allows the same interface to have bindings to for example, SOAP and IIOP.
• ASN . 1 encoding rules are used as a transfer syntax for remote invocations that resemble CORBA / IIOP.
• The inbound flow arrives as an IIOP call just as it does if cross-memory WOLA on the same LPAR was used.
• The distributed object model is based on CORBA . Objects are accessed using the internet inter-ORB protocol ( IIOP ), with some optional extensions.
• RMI-IIOP uses generated code for remote objects and does not require supplementary classes for non-trivial data, unlike CORBA . This results in less complexity and a smaller footprint.
• The network flow from the application to the WAS z / OS system is by way of IIOP . The WOLA connection factory is informed of this IIOP flow to the proxy by way of several new custom properties to the connection pool.

• So if your an externally available SOAP service becomes available as an EJB, one can switch to using RMI / IIOP by just changing the service description ( the WSDL ), without having to make any modification in applications that use the service.
• The package provides the support for the remote communication between applications using the General Inter-ORB Protocol and supports other features of the RMI and RMI-IIOP, this package is for calling remote methods of objects on other virtual machines ( usually via network ).
• This topology has limitations compared to outbound WOLA calls on the same z / OS LPAR : global transactions requiring two-phase commit can not be propagated across the IIOP connection to the WOLA proxy, and the user identity on the WAS thread can not be asserted into the target service on z / OS.
• This tells the local proxy application to treat requested service, which is specified as the JNDI name of the target EJB, as a request to invoke the EJB using IIOP . This requires the local and remote WAS instances to have federated names spaces or operate as a single cell for the JNDI lookup to succeed.
• The architects of this solution chose to leverage an existing element of the WAS z / OS design called " local communications, " a cross-memory mechanism used by WebSphere Application Server for z / OS since the V4 . x days that optimized IIOP traffic between application servers " on the same LPAR ."
• Usage of the term "'RMI "'may denote solely the programming interface or may signify both the API and JRMP, IIOP, or another implementation, whereas the term RMI-IIOP ( read : RMI over IIOP ) specifically denotes the RMI interface delegating most of the functionality to the supporting CORBA implementation.

• An extension to the data carousel is the " object carousel ", which presents downloaded information as objects compatible with the objects defined by the User-User API . ( The choice of download or IIOP protocols is embedded in the object's IOR, so the means of access is transparent to the client application .)
