SOA-enabling software for ClearPath OS 2200

OS 2200 software SOA enablers

• Java– Native JVM implementation

– JBoss application server

– Resource adapters for RDMS, DMS, TIP/HVTIP, DTP services, BIS

– Eclipse plug-ins

• Other OS 2200 SOA-enabling software– OpenDTP (Open Distributed Transaction

Processing)

– MQseries

– DTI (Distributed Transaction Integrator)

– MSMQI (Interface to Microsoft Message Queuing)

– NTSI (Messaging Integration Services)

– CITA (Communications Interface for Transaction Applications)

The right tool

for every job

Java on OS 2200

• Java Virtual Machine– Native implementation on OS 2200

– Integrated with OS 2200 security and file systems

• JBoss– Open source Java EE application server

– Validated, prepackaged and enhancedfor 2200 with security, transactionintegration and more

– Redhat-JBoss offers additional open source products, including JBoss Enterprise Middleware Suite (JEMS) – “The open source platform for SOA.” They are also developing an open source enterprise service bus.

Web Services

• Standardized way to implement SOA over the Internet (or any network)

• Based on XML files and messages

– WSDL (Web Service Description Language) to describe services

– SOAP (Simple Object Access Protocol) to format messages

– Dozens of other standards at varying levels of maturity

• When you want the highest degree of standardization, platform independence, and future flexibility

• When functionality is needed by business partners, clients, and suppliers who operate in a wide variety of computing environments

• When you have technology that supports them, such as the Java EE environment on OS 2200

What are Web Services? When should you use them?

Native OS 2200 middleware

• Described in the OS 2200 modernization white paper:

– OpenDTP – MQseries– DTI– MSMQI – NTSI – CITA

• When you have no need to extend the services outside the data center and your internal, active networks

• When you have real-time performance needs that cannot be met in a Web Service environment

• When you have specific platform and technology integration needs

• When you do not have Java expertise but do have expertise in direct use of these middleware solutions

• When you are using distributed transactions that span services

Remember: SOA and Web Services are NOT

synonymous!

Use native middleware…
