What is CASP?
CASP is a toolkit for WebSphere WSAD / WMQ / WMQI / WAS
development & monitoring.
6
What are the CASP tools?(WebSphere MQ)
1. Open Source API2. File Transfer 3. Data Transformation 4. Simple Microflow5. Systems Management
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
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 accordinglyPuts 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
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’sNo scripting language – GUI drivenTransformation knowledge is moved
“out” to a directory
“The CASP product is very easy to use.” – Software Engineer, Insurance
10
Data Transformation highlights.
Action Builder makes it easy to define mapping rules for transformation.
11
Why Microflow ?
Saves writing “routing” programsSimpler 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
12
Microflow patternLoanService
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

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
18
Web ServicesWeb 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

Simple and Powerful Transformation Engine
Business Services Directory– Metadata Repository– Graphical “Action
Builder” for creating rules stored in directory
Data– Import COBOL
copybooks– Import & export XML
DTD’s
Dynamic conversion of messages– Transformation engine– Application service– Message handling API
- Transforms: XML, Standard record formats (I.e. COBOL)
23
Taking Full Advantage of WebSphere MQ Integrator
Out-of-box solution to integrate WebSphere Application Server with MQSI (WebSphere MQ Integrator)– Automated data warehousing for retrieval and updates– Complex transformation support with data enrichment– Development environment with visual component integration tool– Enterprise data integration and routing

Bridging the “Generation Gap” with Reliable File Transfer
CASP File Transfer– Is not FTP and does not use FTP– Transport over MQSeries for reliability– Optional data compression for faster service– Available on multiple platforms
Types of transfer supported– File-to-File– File-to-Message– Message-to-File
Enabling data exchange to/from any type of application Easy to use between Business Units or Business Partners (Fast B2B integration)

Security for Web and Application Business ServicesMQSecure
– Management and distribution of cryptographic Keys (Digital Certificates)
– Type of Security • Authentication - Verification of the sender• Integrity - Detects if the message was altered• Non-repudiation - Undeniable proof of messages received• Privacy - Message should only be read by its addressee
– Application integration• Transparent to application: Plug-in service, MQ channel exits• APIs to tightly integrate with specific application

Managing WebSphere Application Server
Candle OMEGAMON XE for WAS– Detect and report traffic and resource utilization within each
WebSphere Application Server.– Detect activity levels for each Enterprise Java Bean container
defined in each application server.– Detect activity levels for the enterprise bean object pools associated
with each container.– Detect and report statistics on container transactions.– Activity levels for individual EJBs, including method invocation data.– Detect and report utilization and contention for the database
connection pools associated with each application server. – Detect and report activity levels associated with each Web
application running in each application server’s servlet engine.– Report statistical information on HTTP sessions.– Reports showing activity level (CPU time) associated with each class
and class method currently loaded into the JVM.– Thread-related activity, such as CPU time per thread, and the
number of active threads.
