1 Overview of WLEC to Oracle WebLogic Tuxedo Connector Migration

This chapter describes the requirements and procedures to migrate WLEC applications to the Oracle WebLogic Tuxedo Connector.

This chapter contains the following sections:

Guide to this Document

This document introduces the Oracle WebLogic Tuxedo Connector application development environment. This document provides information on how to migrate WLEC applications to use the Oracle WebLogic Tuxedo Connector to interoperate between Oracle WebLogic Server and Oracle Tuxedo.

The document is organized as follows:

Overview

WLEC is a deprecated service in WebLogic Server 8.1. WLEC users should begin plans to migrate applications using WLEC to the Oracle WebLogic Tuxedo Connector.

Oracle WebLogic Tuxedo Connector provides bi-directional interoperability between WebLogic Server applications and Tuxedo services. The connector allows WebLogic Server clients to invoke Tuxedo services and Tuxedo clients to invoke WebLogic Server Enterprise Java Beans (EJBs) in response to a service request.

WLEC to Oracle WebLogic Tuxedo Connector migration requires minor application modification:

Prerequisites

Before you can start migrating your WLEC applications to Oracle WebLogic Tuxedo Connector, make sure that you have installed:

Key Differences Between WLEC and Oracle WebLogic Tuxedo Connector

Table 1-2 provides information on key administration, configuration, and programming differences between Oracle WebLogic Tuxedo Connector and WLEC.

Table 1-2 WLEC and Oracle WebLogic Tuxedo Connector Key Differences

Description Oracle WebLogic Tuxedo Connector WLEC

Connectivity

Uses the Tuxedo /T Domain gateway. The gateway creates a single network link between a WebLogic Server instance and a Tuxedo domain for all method invocations.

Uses a pool of connections and each invocation is sent over a connection obtained from this pool.

Failover Management

Uses Tuxedo domains.

Uses a failover list.

Object Routing

CORBA calls from WebLogic Server applications are propagated to the Tuxedo CORBA environment using the TGIOP/TDOMAINS protocol.

CORBA calls from WebLogic Server applications are propagated over IIOP connection pools using the CORBA API.
