AquaLogic Service Bus architecture is centered around an Enterprise Service Bus. The bus provides message delivery services, based on standards including . BEA Systems, Inc. was a company specialized in enterprise infrastructure software products . BEA AquaLogic Service Bus, an enterprise service bus ( ESB) with operational service-management that allows the interaction between services. BEA Systems AquaLogic Service Bus Despite limited built-in support for integration with external data sources, excellent Web services.

Concepts and Architecture
Cross Site Request Forgery. Create a new AquaLogic Service Bus domain in which to develop the tutorials. It supports XML as a native data type, while also offering alternatives for handling other data types. Communication between different departments is achieved through a federated network of ESBs, which talk ubs each other, often through firewalls.
The following conventions are used throughout this document:. AquaLogic Service Bus supports the following capabilities for the transformation or processing of messages:.
The tutorial files contain properties that you must set to run the tutorials. AquaLogic Service Bus built-in test console is a browser-based test environment used to validate resources and inline XQuery expressions used in the message flow.
Stores information about services, schemas, transformations, WSDLs Web Service Definition Languageand WS Policies Provides centralized management and distributed access to resources and services Allows browsing of aqualoogic registered in AquaLogic Service Bus and import of resources from WebLogic Workshop or other applications Allows the propagation of configuration data from environment to environment for example, from a development domain to a test domain to a production domain.
This step is only for Windows users.
Aqualogic Service Bus – How is Aqualogic Service Bus abbreviated?
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. Articles containing potentially dated statements from All articles containing potentially dated statements. The context can be read and modified by XQuery expressions and updated by transformation and in-place update actions.
Retrieved from ” https: This logic includes such activities as transformation, publishing, and reporting, which are implemented as individual actions within the stages of a pipeline. This cluster can host other applications in addition to AquaLogic Service Bus. There is one administration server in every clustered domain.
In this tutorial you will see the benefits of using AquaLogic Service Bus acting as an intermediary aqualogi clients and business services.
Introduction to the BEA AquaLogic Service Bus Tutorials
The message-brokering engine accesses this configuration information from its metadata cache. EJB transport makes retry decisions based on the nature of the failure that can occur during the invocation of an EJB.
After a message is sent to an endpoint either a business service or asualogic proxy service aaualogic, AquaLogic Service Bus processes the response message in a similar model as that described in the preceding sequence of events. The WebLogic security framework divides the work of securing a domain into several components providerssuch as authentication, authorization, credential mapping, and auditing.
It is intended for integration-focused IT architects responsible for messaging and service oriented architectures SOA. All were former employees of Sun Microsystemsand launched the business in by acquiring Information Management and Independence Technologies.
Java programs or scripts can be used to automate deploying an application or for moving a configuration from staging to production. Feeds or widget will contain only vulnerabilities of this product Selected vulnerability types are OR’ed.
This functionality supports an orderly promotion process of AquaLogic Service Bus resource configurations from staging and test environments into production and minimizes the expertise, time, and resources needed to achieve various deployment scenarios. The EJB transport provides the following capabilities:. The service bus uses the new service and resource configuration when changes are activated.
In the tutorial you use four different business services. Since a proxy service can route messages to multiple business services, a proxy service can be configured with an interface that is independent of the business services it communicates with.
They are the interface that service consumers use to connect with managed back-end services. There are NO warranties, implied or otherwise, with regard to this information or its use. It is used to resolve differences in requirements between business services and service clients. With AquaLogic Service Bus message brokering, service clients exchange messages with an intermediary proxy service rather than working directly with a business service.
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 it as a search index.
EJB transport can take advantage of scenarios in which the same EJB is deployed in multiple domains or on a cluster for load balancing or failover or both. Working through the tutorial you will: Install AquaLogic Service Bus. Henley Mark Hurd Jack F. The build script is used to build each of the services.
To deploy the business services to your running tutorial domain, you must modify the properties responsible for specifying the WebLogic Server behavior.
Operators have privileges to edit operational settings, create new SLA alert rules, and create and edit alert destination resources. Using this customization feature, imported bbus can be tailored for the new domain before activating them. The applicants credit rating information is required in one of the scenarios to setvice the loan request.
To deploy the Web service, enter antthen press Enter. The AquaLogic Service Bus security model includes the following:. Predefined context variables contain information about the message, transport headers, security principles, metadata for the current proxy service, and metadata for the primary routing and publishing services invoked by the proxy service.
The following figure shows the flow of message data in a basic AquaLogic Service Bus cluster topology. Message processing logic is specified in message flow definitions when defining a proxy service. Transforming a Loan Application describes how to configure your existing AquaLogic Service Bus configuration to address the new requirement of adding a transformation stage.
AquaLogic Service Bus enables management and coordination of many distributed service endpoints, thereby providing centralization in the enterprise. Servuce configure the logic for the manipulation of messages in proxy service message-flow definitions.
For more information on proxy services, servic Proxy Services. 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:.
The request pipeline definition specifies the actions that AquaLogic Service Bus performs on request messages to the proxy service before invoking a business service or another proxy service.
