INT403: How to Implement an EAI Architecture with Sybase Technologies Marius Roets System Manager: Integration Solutions MariusRoets@woolworths.co.za August 15-19, 2004
Agenda • Overview of Woolworths • Rules for implementing an Enterprise Application Integration Strategy • Critical Success Factors for Application Integration • The Integration Competency Center • Benefits for Woolworths • Woolworths Technical Environment • Existing integration architecture challenges • Sybase Technology as part of the EAI Architecture • Questions
Overview of Woolworths • Store environment • 180 Corporate stores in South Africa • Textiles: 180 • Foods: 120 • 55 Franchise stores • 50 International stores • 25 Cross Border Stores • 5 Convenient Franchise Foods stores @ petrol stations Distribution Centers • 3 Textile DC • 4 Foods DC
Rules for implementing an Enterprise Application Integration Strategy • Create an application integration competency center. • Develop an integration city plan for your enterprise. • Focus on both B2B and A2A. • Document all application interfaces. • Select integration products by focusing on key requirements. • Run a proof of concept before buying. • Select the right implementation partner.
Critical Success Factors for Application Integration • Executive Sponsorship. • Appoint the best resources into the integration competency center. • Start off Right: Selecting your Enterprise Integration Broker. • Looking Beyond “Silos”. • Limiting Customization in legacy applications. • Plan for Professional Services. • No “One-Size-Fits-All” Integration Solution. • Organization is crucial.
Key Objectives of the Integration Competency Center • Get application integration recognized as the formal discipline it needs to be for the business and IT • Combine the skills and processes associated with application integration into a single group, making better use of a scarce resource • Build and develop skills, capability and best practices for integration processes and operations • Monitor and assess integration technology and tools and select a flexible set of approved tools
The Skills of the Integration Competency Center • Middleware Specialists • Interface Designers • System and Software Engineers • Operational Support Specialists • Leadership, Management and Relationship Management
How would a competency center group relate to an architectural group? • Potentially significant overlaps between the integration group and any existing architectural group. • The key difference is that the competency center brings together • architectural, • development and • operational roles into one group. • The character of the groups is also different — architects design, teach and move on, but much of what the integration group does is more mundane. • Those with architectural roles within the integration group can, and indeed should, play an active role in the architectural group.
Benefits for Woolworths • Preserves existing systems – minimal impact on existing architecture • Integrated, comprehensive solution • Component-based architecture on Sybase e-Biz Impact Integration broker simplified maintenance • TCO for integration broker very affordable for business • Integrated architecture help business to think differently how they want to implement new systems/applications • Integration architecture assist in the implementation of business activity monitoring
Overview of the technical environment • More than 250 business applications in Woolworths • Application hardware platforms • Mainframe – MVS – 2 LPARS (110 MIBS) • AIX Unix – All stores (store back office applications), all DC’s & head office • AIX Unix – Data warehouse (3 TG Informix database) • AIX Unix MQ Server Cluster • Microsoft Windows 2003 servers on IBM & Dell servers – 50 Applications servers & 3 MS SQL Server database clusters

Existing Integration environment in Woolworths Hardware: 2 * IBM Netfinity Servers in Microsoft Windows 2003 Cluster for Impact 4.1 & 5.3 4 GB memory, 8 * 2 GHz processors, 300 GB disk 2 * Dell Power Edge Servers in Microsoft Cluster for Microsoft SQL Server 8 GB memory, 4 * 800 MHz processors, 600 GB disk Software: Sybase Impact v4.1 in production Sybase E-Biz Impact v5.3 in production Sybase Adaptive Server Anywhere (Unix / NT) Sybase Enterprise Application Server Sybase Enterprise Portal Opalis Robot – Windows Scheduler Microsoft MOM – Management & monitoring SQL Server 2000 Enterprise edition Informix 9 on Unix platforms (Stores, DC, Data warehouse) WebSphere MQ Server v5.3 for Windows NT & Unix WebSphere MQ Server v5.2 for IBM Mainframe Qpasa for WebSphere MQ management Q-Liner for FTP compression over FTP / MQ / TCP Postilion – Payment Gateway to banks SMS Enterprise Server
Existing Integration environment in Woolworths • Mainframe • 150 different transaction types (Assembler, Cobol, Easytrieve) – Plan to migrate all of this onto Impact v5.3 before October 2003 • 0.5 million transactions per day from/to mainframe (3 GB data / day) • Average MAP message size 1 MB, reading 55 MB for some interfaces • Main protocol is FTP, but MQ is also used in some interfaces to/from mainframe • Impact v4.1 configuration • 240 different transaction types • 30% of interfaces are database acquisition and/or delivery aims • 40% of interfaces are MQ interfaces • 10% of interfaces are Microsoft DCOM interfaces • 8 interfaces use TCP/IP Socket for interfacing with banks and mainframe (CICS transactions) • 10% of interfaces are Flat file / FTP interfaces • Process 5 GB data / day
Existing Integration environment in Woolworths E-Biz Impact v5.3 statistics • 65 different transaction types • 30% of interfaces are database acquisition and/or delivery aims • 40% of interfaces are MQ interfaces • 2% of interfaces are Microsoft DCOM interfaces • 1 interfaces use TCP/IP Socket for interfacing with banks and mainframe (CICS transactions) • 28% of interfaces are Flat file / FTP interfaces Impact v5.3 configuration • 5 Clusters • 13 Controllers • 29 Applications
Existing integration architecture challenges • Real-time interfaces into business logic that exist in Java classes and Microsoft COM+ components • Real-time interface from Java classes and Microsoft COM+ components to receive messages for processing in Sybase e-Biz Impact • Unified comprehensive web front-end for the integration database and documentation that is accessible from different hardware devices. • Guaranteed delivery of interfaces into web services. • Integration strategy must assist in bringing the TCO of information technology down. • Integration architecture is the base platform for delivering business activity monitoring.
Sybase Technology as part of the EAI Architecture • Sybase Enterprise Application Server (EAServer) • Use EAServer to create web services for e-Biz Impact • Integrate into Java business logic from e-Biz Impact through JMS & EAServer • Integration into Microsoft DCOM+ from e-Biz Impact through JMS & EAServer • EAServer is the application server for our integration portal that runs on Sybase Enterprise Portal
Sybase Technology as part of the EAI Architecture • Sybase Adaptive Server Anywhere (ASA) • Store transmission system (180 stores) • Use it as a staging database in the store environment for the MQ components • ASA runs on AIX O/S that IBM does not support anymore (ASA v6 for AIX v4.1, ASA v9 for ASA v4.3 or higher) • Security database for e-Biz Impact run on ASA v8.0 • Sybase South Africa develop a management console to monitor and manage all the ASA databases centrally from Woolworths service management center.
Sybase Technology as part of the EAI Architecture • Sybase Enterprise Portal • Sybase Enterprise Portal is the integration team management portal for all interfaces • Functionality implemented in Sybase Enterprise Portal: • Data flow alert application to manage all alerts from applications, interfaces & infrastructure • Interface documentation repository • Resend application for messages to/from e-Biz Impact v5.3 and/or Impact v4.1 • Impact v4.1 / E-Biz Impact v5.3 database configuration application for the management of interface configuration • New store / Store conversion application for the management of interface routing
Sybase Technology impact on integration competency • Pro • One vendor that support Woolworths integration strategy • Local support available from vendor • Integration challenges between different Sybase product easier because one vendor look after all our products in the integration competency • Development resources available from Sybase South Africa for projects • Cons • More technology & applications to support in the integration competency • Skill level of integration competency not always inline with the technology directions of the different Sybase products. • Platform certification timing issues
Closing • Enterprise application integration is a complex endeavor, but it’s feasible if addressed properly. • Technology is not the most important aspect of application integration initiatives. • Proper organization and a clear understanding of your short-term and long-term needs maybe as critical as choosing the “best” product.
