In AquaLogic Service Bus, monitoring statistics are gathered locally and aggregated centrally.
You can explore the other directories as an exercise. Aqualohic following four elements are used to construct a message flow:. Read-access to databases from proxy services is supported without requiring writing of a custom EJB or custom Java code and without the need for a separate database product like AquaLogic Data Services Platform. It is used to resolve differences in requirements between business services and service clients. The default route node is an echo node that reflects the request as the response.
They are definitions of the enterprise services with which you want to exchange messages.

You will learn how to configure and use AquaLogic Service Bus to resolve the business scenarios presented in the specified use cases. The system allows environment specific settings to be overridden during import. SLA rules are run against aggregated data and the system raises alerts, following which services can be enabled or disabled. See how message processing by AquaLogic Service Bus is driven by metadata specified as the message flow definition for a proxy service in the AquaLogic Service Bus Console.
This tutorial focuses on the configuration of the proxy service. An EJB can be exposed as a Web service, without the need for tools or the modification of the legacy code on the application server that hosts the EJB.
A high performance message broker is a core component of AquaLogic Service Bus. Change the port number to the port number of the tutorial domain. Selected vulnerability types are OR’ed. After the server is started, you must run a build script to:.
Introduction to the BEA AquaLogic Service Bus Tutorials
Design time testing helps isolate design problems before deploying a configuration to a production environment. AquaLogic Service Bus built-in test console is a browser-based test environment used to validate resources and inline XQuery aqualovic used in the message flow.
Complete the first tutorial, Routing a loan application, to become familiar with BEA AquaLogic Service Bus, then proceed to the other tutorials provided as part of the tutorial suite: This section provides an architectural overview of AquaLogic Service Bus and highlights operational features that enable rapid service integration, provisioning, and management across a heterogeneous IT infrastructure.
AquaLogic Service Bus manages the routing and transformation of messages in an enterprise system to promote seamless application integration. The dynamic routing capability also simplifies configuration of such a network. The files structure for each of the business services is the same—the directory structure for one of the business services, the normal service, is described in the following table.
For more information on proxy services, see Proxy Services. Using this customization feature, imported resources can be tailored for the new domain before activating them.

For each business service: The inbound transport layer is the communication layer between client services or service consumers and AquaLogic Service Bsu. A proxy service can aquaogic messages to multiple business services; you aqualgoic choose to configure a proxy service with an interface that is independent of the business services with which the proxy service communicates.
AquaLogic Service Bus supports best practices for change management in enterprise systems by configuration of resources and services in a controlled environment. Create a new AquaLogic Service Bus domain in which to develop the tutorials. Gather statistics about message invocations, errors, performance characteristics, messages passed and SLA violations Send SLA-based alerts as SNMP traps, enabling integration with third-party ESM solutions Support for logging selected parts of messages for both systems operations and business auditing purposes Search capabilities by extracting key information from a message and use as aqualogoc as a search index.
This tutorial highlights specific features available in AquaLogic Service Bus.

The message processing by Serivce Service Bus is driven by metadata, specified in the message flow definition of a proxy service. The tutorial files contain properties that you must set to run the tutorials. Transforming a Loan Application describes how a proxy service is configured with a routing node, transformations, and a Web service callout WS-Callout to allow content based routing and message enrichment through AquaLogic Service Bus.
It enables content-based routing of messages and data transformation. You configure the logic for the manipulation of messages in proxy service message-flow definitions.
There are NO warranties, implied or otherwise, with regard to this information or its use. For this tutorial, create a domain named ServiceBusTutorialand select development mode and the default PointBase database. Messages fed into the pipelines are accompanied by a set of message context variables that contain the message contents and can be accessed or modified by actions in the pipeline stages. The test servixe can test specific parts of a system in isolation and it can test a system as a unit.
AquaLogic Service Bus message brokering capabilities are implemented with the following operational features:. A route node used to define the message destination.
