Standard  #1
Key Features of Varadhi
Optional
Varadhi IDL compiler (idlc)
IDL (Interface Definition Language) allows developers to define their
interfaces in a standard language that is independent of any
implementation language (like C++ or Java).
WSDL (Web Service Description Language) is a XML based language
which is used to describe the interfaces for a web service.
idlc generates stub/skeletons for C++ and Java (client) Languages.

Varadhi configuration tool (vconf)
vconf allows developers to configure the ORB and generate a target platform which makes it easy to use Varadhi with various target operating systems.
vconf allows developers to statically determine memory footprint and configure various other parameters like features to be supported and protocol to be used.

11. Key Features of Varadhi
Standard  #4
Key Features of Varadhi
Optional
Varadhi IOR tool (dumpior/iortool)
dumpior is a tool for displaying the contents of an IOR (Interoperable Object Reference) stored in a file.
iortool enables the creation of object group references.

12. Protocols Supported

13. Key Features of Varadhi
Standard  #5
Key Features of Varadhi
Optional
Support for GIOP 1.1/1.2 (General Inter-ORB Protocol)
GIOP is a standard messaging protocol, which facilitates
interoperability between ORBs.
SANKHYA Varadhi provides support for GIOP 1.1 and GIOP 1.2

14. Key Features of Varadhi
Standard  #6
Key Features of Varadhi
Optional
Supports SOAP (Simple Object Access Protocol)
SOAP is part of the Web Services 1.0 specification. Varadhi
includes support for SOAP.
Interoperability between Web Services and CORBA based application.

15. No application runs in an island.
When you use Varadhi to develop your distributed applications,
Integrating your applications with other third-party or legacy
applications can be surprisingly simple.

16. SANKHYA Varadhi Core Features

17. Key Features of Varadhi
Standard  #7
Key Features of Varadhi
Optional
Static CORBA
In static CORBA, type information should be available to build
clients and servers applications. All the type information will be
present in the stubs and skeletons generated by idlc compiler from a
given IDL file. To build the client application, the stubs will be linked
and to build server application, skeleton will be linked.
Using Varadhi’s idlc compiler, stubs and skeletons can be generated
for a given IDL file.

18. Key Features of Varadhi
Standard  #8
Key Features of Varadhi
Optional
Dynamic CORBA
In certain situations, type information may not be available when
clients and servers are built. In these cases, the clients and servers
should be able to dynamically enquire the type information, invoke
operations, and service requests.
SANKHYA Varadhi provides an Interface Repository to store
type information, and supports Dynamic Invocation Interface for
dynamic invocation of operations and Dynamic Skeleton Interface for
dynamic handling of requests.
Cont …

19. Key Features of Varadhi
Standard  #9
Key Features of Varadhi
Optional
Dynamic CORBA
Dynamic features are used in clients that browse through objects and
then make invocation on them based on dynamic selection process.
This is not possible with static clients where all the objects and their
interfaces must be known at compile time. Dynamic features are useful
for creating bridges between CORBA and non-CORBA systems, and for
creating system management tools.

20. Key Features of Varadhi
Standard 
#10
Key Features of Varadhi
Optional
Supports Multi-Threading!
A single-threaded environment will cause bottleneck in the
performance of an enterprise level server application, reducing its
throughput and scalability. Using multiple threads provide concurrency
and improves the overall throughput.
SANKHYA Varadhi supports configurable thread safe feature for use in
multi-threaded application environment. Since the ORB run-time is
re-entrant, it can be used in multi-threaded applications.
SANKHYA Varadhi simplifies multithreaded application development by
providing OS independent multithreading APIs.

Standard 
#11
Key Features of Varadhi
Optional
Supports Multi-Threading!
Multi Threading results in numerous advantages as applications can be
developed without having to bother about request scheduling and
operation dispatching as these activities are performed by Varadhi.
Varadhi allows server applications to process multiple requests
simultaneously.
Multi-threading can also improve the efficiency and predictability of
client and server applications.

47. About OMG
The Object Management Group, Inc. (OMG) is an international organization supported by over 800 members, including information system vendors, software developers and users. Founded in 1989, the OMG promotes the theory and practice of object-oriented technology in software development. The organization's charter includes the establishment of industry guidelines and object management specifications to provide a common framework for application development. Primary goals are the reusability, portability, and interoperability of object-based software in distributed, heterogeneous environments. Conformance to these specifications will make it possible to develop a heterogeneous applications environment across all major hardware platforms and operating systems.
OMG's objectives are to foster the growth of object technology and influence its direction by establishing the Object Management Architecture (OMA). The OMA provides the conceptual infrastructure upon which all OMG specifications are based.

48. About CORBA
CORBA (Common Object Request Broker Architecture) is an open distributed object computing infrastructure standardized by OMG, the Object Management Group. The CORBA specification is based on OMG's Object Management Architecture (OMA) for object technology. CORBA specification is the standardized solution for reusability for object technology. CORBA specification is the standardized solution for reusability, portability and interoperability of object based software in distributed, heterogeneous environment. The ORB provides the mechanisms by which objects transparently make requests and receive responses, providing interoperability between applications on different machines in heterogeneous distributed environments.
