IIOP and GIOP Protocol Support
Internet Inter-ORB Protocol (IIOP) is the standard protocol that different ORBs must use to
communicate across the Internet. This protocol is standardized by the OMG. Because the objects that you
write in NonStop CORBA comply with IIOP they can be used by other ORBs and clients, and NonStop
CORBA clients can use the objects located on other ORBs that support IIOP.
NonStop CORBA 2.6 supports GIOP versions 1.0, 1.1, and 1.2. If a client from another ORB uses an
earlier version of GIOP, NonStop CORBA automatically adopts that version.
IDL Compiler
The NonStop CORBA IDL compiler (NSDIDL) is based on the CORBA 2.6.1 specifications defined by
the OMG. Any differences between the specification and the NonStop CORBA implementation are noted
in the NonStop CORBA 2.6 Programmer's Reference. The compiler generates stubs and skeletons for use
by client objects and server objects, respectively.
Language Bindings
NSDIDL supports OMG standard C++ and Java language bindings, as defined in the OMG binding
specifications. Any differences between the specification and the NonStop CORBA implementation are
noted in the NonStop CORBA 2.6 Programmer's Reference.
Portable Object Adapter
The NonStop CORBA Portable Object Adapter (POA) supports the function defined in the CORBA
specification. An Object Adapter is the primary way that an object implementation accesses the services
an ORB provides.
The NonStop CORBA POA:
Allows for development of portable object solutions●
Provides for objects that persist over long periods of time●
Allows a servant to manage multiple objects as one logical object (A servant is a user-defined
object that provides an implementation of the methods of an interface.)
●
Allows multiple distinct instances of a POA to exist in a server●
Supports transient objects●
