5 What is CASP? CASP is a toolkit for WebSphere WSAD / WMQ / WMQI / WAS development & monitoring. 5

6 What are the CASP tools? (WebSphere MQ) 1. Open Source API 2. File Transfer 3. Data Transformation 4. Simple Microflow 5. Systems Management 6

7 Why an Open Source Wrapper? With Open Source, you are not tied to the vendor. Save money on developers. Save programmers from making expensive mistakes. Move MQ knobs and dipswitches out to a directory. Typical build time is 3 to 6 months architect/developer. Ongoing maintenance and support issues. No need to learn what s underneath the wrapper. Allows for adding more functions hidden under the wrapper. Open Source means that you can retrofit your existing wrappers without changing existing programs. CASP [Open Source APIs] ability to externalize the MQ configuration is exceptional. -Architect, Florida Health Care 7

8 Why File Transfer? Current choices Use the IBM Sample programs shipped with MQ file to Q, Q to file. FTP that comes with TCP/IP. Home grown (in/out/self sourcing) A Cadillac CASP is middle of the road and priced accordingly Puts Your File Transfer Process process under the same management as messages. Compression I am amazed at CASPs ability to import our entire Floor Plan copybook in one pass. - VP of Architecture Financial Services 8

9 Why Data Transformation? Start small, move to a complex Broker if needed It s an entrée to XML (because it does XML) Import Copybooks and DTD s No scripting language GUI driven Transformation knowledge is moved out to a directory The CASP product is very easy to use. Software Engineer, Insurance 9

10 Data Transformation highlights. Action Builder makes it easy to define mapping rules for transformation. 10

11 Why Microflow? Saves writing routing programs Simpler and cheaper than leading workflow products. Don t need to hard wire Q names etc. Allows you to dynamically change business logic AFTER it s written and in production. Service-Oriented Architecture 11

12 Microflow pattern LoanService 12

13 Why Systems Management? Things like Audit and Logging are used by most customers for message replay. Which costs 2-3 months to build yourself. Error Management System (EMS) allow you build common reusable error management processing. Feeds into vendor products CCC, Omegamon XE. Allows a deeper view than just MQ Monitoring - getting ready for serious computing Candle Leads the WebSphere MQ Monitoring and Management Market Place GartnerGroup,

16 What are the CASP tools? (Web Services WSAD/WAS) 1. Web Services / 2. SOAP Processor 3. Message Driven Beans 4. EJB Content-Based Routing 5. Full IBM Integration (CICS/IMS/WMQI) 6. Systems Management 16

17 Web and Application Services Reduce projects and maintenance costs by 50% Faster completion of projects with less code and complexity Reduce cost by reducing the number of developers and consultants required to complete a project Reduce risk by using proven technology that includes prepackaged services 17

18 Web Services Web services directory allows services to be invoked dynamically using XML and internet standards from a program or Web browser UDDI is a specification for web-based information repositories of Web Services UDDI uses TCP/IP, HTTP, XML, SOAP and WSDL to allow uniform service description format and service discovery protocol Services in WSDL that allow businesses to publish and find them 18
