CORBA 2.3.3 Getting Started Guide (NonStop CORBA 2.3.3+)

CORBA can interoperate with other heterogeneous OMA-based environments that comply with the

CORBA IIOP protocol.

Also noteworthy, NonStop CORBA is language-compliant and object-adapter compliant with the OMG's

CORBA ORB portability specification, which enhances the interoperability of the components you write

using NonStop CORBA.

Writing client and server objects compliant with CORBA 2.3 offers the following benefits:

Interoperation with other CORBA-compliant ORBs●

Wide area network (WAN) and local area (LAN) network connectivity based on international

networking standards

●

Ability to wrap legacy applications with a distributed object architecture (an advantage of NonStop

CORBA)

●

Features of NonStop CORBA

By implementing certain system-specific processes using TS/MP server classes or server pools (the

preferred terminology), the ORB provided with NonStop CORBA offers availability and scalability

advantages over other CORBA-compliant ORBs. TS/MP runtime code resides in every ORB running

NonStop CORBA and can also be included in your NonStop CORBA application servers.

The NonStop CORBA ORB runs on Compaq NonStop Himalaya systems. The NonStop CORBA

application servers that you write in C++ or Java use this ORB for communication to and from remote

clients. The major features differentiating the ORB supplied with NonStop CORBA from other ORBs

are:

Scalability of the ORB to support higher throughput●

Scalability of application server processes across CPUs●

Compatibility of NonStop CORBA components●

Availability and fault tolerance●

Transaction protection for data stores managed by the NonStop TM/MP and database software●

Network session concentration to reduce the number of IP ports needed in the host●

Advantages of the Pathway environment●

Scalability of the Object Request Broker (ORB)

With NonStop CORBA, you can increase the ORB capacity without disturbing running applications.

NonStop CORBA provides several ways of scaling the ORB itself:

Scalability of the ORB to support higher throughput New clients can connect to the NonStop●
