Introduction: Object Request Broker

Explore the key concepts pertaining to applications that use the Object Request Broker (ORB). The product uses an ORB to manage communication between client applications and server applications as well as among product components. These Java 2 Platform Enterprise Edition (J2EE) standard services are relevant to the ORB: Remote Method Invocation/Internet Inter-ORB Protocol (RMI/IIOP) and Java Interface Definition Language (Java IDL). The ORB provides a framework for clients to locate objects in the network and call operations on those objects as though the remote objects were located in the same running process as the client, providing location transparency.

Object Request Broker (ORB)

An Object Request Broker (ORB) manages the interaction between clients and servers, using the Internet InterORB Protocol (IIOP). It enables clients to make requests and receive responses from servers in a network-distributed environment.

Logical pool distribution (LPD) thread pool

The Logical pool distribution (LPD) thread pool mechanism implements a strategy for improving the performance of requests that have shorter run times. Do not configure LPD unless you have already configured it in a previous release of WebSphere Application Server. LPD is a deprecated function and will be removed in a future version of the product.
