o Integration Gatewayo Integration Engineo Connectorso Gateway Managero Transaction

• Integration Broker Architecture• Integration Scenario• Connector Usage

Introduction & terminologies-Introduction

• Middleware Technology that facilitates synchronous and asynchronousmessaging among internal systems and trading partners

• Modular design – Elements developed for integration can be reused

• Comprises of two high level sub-systems, Integration Gateway andIntegration Engine.

Introduction & terminologies-Integration

Broker Elements• Integration Gateway

• Integration Engine

• Connectors

• Gateway Manager

• Transaction

Introduction & terminologies-Integration

Gateway• Platform that manages the actual receipt and delivery of messages

• Provides the support for the leading TCP/IP protocols used

• Provides the extensible interfaces for the development of newconnectors for communication with legacy, ERP and internet based systems

• Backward compatibility for XML links and Application Messaging

• Maintains basic logging information for message receipt, delivery and errors

• Capable of message format management.

Introduction & terminologies-Integration

Engine• Runs on the PeopleSoft Application Server.• Produces and consumes messages for the application• Receives the messages through one or more separately installed

integration gateways• Treats the gateways as “Black Box” and communicate with them

using standard connectors• Can adapt the elements of existing integration to produce new

integration with minor changes• Handles the messages containing the data in a variety of formats like

PeopleSoft rowsets, XML documents, Simple Object Access Protocol(SOAP) and unstructured data

• Sends and receives the messages synchronously or asynchronously• Applies message transmission type and routing based on specification

defined in PIA component• Transforms message structure and translate data content• Handles the security features

Introduction & terminologies-Connectors

• Two basic type of connectors used in Integration Gateway• Listening Connectors• Target Connectors

• Supports asynchronous, synchronous and polling based message handling

• Connectors are configurable based on user-defined setting at integration gateway and node level

Introduction & terminologies-Gateway

Manager• Processes every message that flows through the integration gateway

• Maintains links among the other major integration gateway components

• Invoked by listening connectors on receiving the message request

• Uses handles on messaging objects, IBRequest and IBResponse todetermine how to route each message

• Uses number of services during each stage of operations

• Invokes the appropriate target connector based on the contents of themessage object and waits for the response from target connector. On receiving the response, it forwards the response to the calling listening connector.

Introduction & terminologies-Gateway

Services• Error Handling: Standard error handling interface that is exposed to each

connector. Provides error handling and error logging for most connectors

• Messaging Objects: There are two objects service in the Integration gateway• IBRequest• IBResponse

• XML Parsing: Used to parse and traverse XML data stored in content section of message

• Message Validation: Used for basic validation such as making sure themessage identifies requestor and message name etc. to ensure thatintegration engine and the target application can process them.

Introduction & terminologies-Gateway

Services• Connector Management: Comprises of several smaller services to

Manage connectors in Integration Gateway.Processes each IBRequestTo determine the appropriate connector to call in each situation. AlsoProcesses the IBResponse returned by each connector.

• Error & Message Logging: Standard logging interface that mostcomponents in the system use. Enables the administrator to quicklydrill-down on problems or review message logs.

• Sample URL for checking errors in development environment. http://peoplesoftsvr.i-flex.com:81/PSIGW/errorLog.html

Introduction & terminologies-Transaction

• Basic unit of work in Integration

• Associated with a specific node

• Used to designate a message that the current node can send or receive

• Defines the message as inbound / outbound message

• Defines transmission type I.e. Synchronous / Asynchronous

• Four basic types of Transaction Outbound Asynchronous (OutAsync) Outbound Synchronous (OutSync) Inbound Asynchronous (InAsync) Inbound Synchronous (InSync)

Application Server - PUB/SUB services

(Application Server)•Resides on the Application Server as a Messaging Server Process

•Sends and receives messages for the application through the IB Gateway

•Consists of Publication Broker, Publication Contractor and Subscription Contractor

Jolt & Tuxedo

Jolt & Tuxedo

• Jolt is an application-layer network protocol that runs over TCP. It is proprietary and owned by BEA and was developed as the means for allowing Java applications to communicate with Tuxedo (also a BEA product).

• Tuxedo is a C-based OLTP monitor that multiplexes user sessions and transactions into a RDBMS and controls transaction execution. In a PeopleSoft system, C++ logic that interprets and executes application business rules and functionality run as services within the Tuxedo domain(s), with Tuxedo managing DB transaction boundaries and queues of requests.

• The role of PIA web servers is to create and manage presentation only.

• At runtime, all business logic executes in Tuxedo.
