The WebSphere eXtended Transaction Runtime (WXTR) Feature Pack for Modernizing Oracle Tuxedo Applications extends WXTR's core value proposition of application modernization. The Feature Pack provides you application modernization capabilities and revitalization for existing Tuxedo style applications, by unlocking the value of these applications and extending them to use Java EE technologies. It simplifies the process of migrating Tuxedo applications onto WebSphere Application Server (WAS), complementing similar functionality provided by IBM WebSphere Application Server Migration Toolkit to migrate Oracle WebLogic applications to WAS. The current version of the feature pack allows you to take your Tuxedo COBOL and C applications and host them natively in WAS using WXTR, with minimal changes.
WXTR enables progressive modernization of existing COBOL and C application skills and assets, while reducing the risks associated with typical modernization strategies. It provides the following core benefits to customers:
- Capitalizes on enterprise-wide skill sets to effectively optimize and innovate COBOL and C assets while consolidating infrastructure around WebSphere Application Server, the industry's leading J2EE standards compliant application server.
- Increases operational efficiency by using simplified, unified administration capability to centrally manage multi-language workloads.
- Simplifies integration complexity and improves agility of the enterprise's service-oriented architecture (SOA) enabled application infrastructure to support growth.
- Improves productivity and efficiency through seamless problem determination and development across mixed language applications.
Programmers get complete autonomy to code and test in a mixed language environment, either in COBOL, C or Java using Rational® application development tools. The current version of the feature pack provides two broad sets of capabilities:
- Runtime environment: The runtime environment runs Tuxedo applications unchanged within WebSphere Application Server, thus modernizing them in context. The runtime provides a mapping of functionality between Tuxedo and WXTR thus simplifying application migration.
- Migration Assist tooling: These tools aid in simplifying the entire process of migration, spanning from profiling applications, identifying sections that might need changes to manage optimal functional mapping to building and deploying the applications on the runtime environment.
Key aspects of the Feature Pack include:
- High performance OLTP for hosting Tuxedo ATMI style applications: Leverage excellent reliability, availability and scalability features of WXTR to host and manage mission critical Tuxedo applications written in COBOL and C.
- Reuse of existing core business application assets: Existing Tuxedo applications can be reused within WebSphere Application Server and extended seamlessly using the SOA connectivity.
- Leveraging existing skills across the enterprise: Existing COBOL, C and Tuxedo skills can continue to be used to maintain and manage existing Tuxedo applications. Newer applications can be developed in Java for deployment into WebSphere Application Server.
- Minimize application changes during migration: Inbuilt support for handling ATMI style APIs using underlying transactional functionality provided by WXTR significantly reduces application changes during migration
- Simplified integration and management of mixed language workloads: Common administration console within WebSphere Application Sever for managing COBOL, C and Java workloads.
"Customers can use this exciting new WXTR Feature pack alongside the IBM WebSphere Application Server to progressively modernize their Oracle Tuxedo applications" said Dave Andrews, Director, Software Development, IBM. "Migration between different transaction processing platforms can be complex and risky without the right set of tools. With WXTR and this feature pack, such risks associated with the migration from Tuxedo are significantly reduced and the migration process itself vastly simplified. This feature pack along with the WebSphere Application Server migration toolkit enable customers to migrate their Oracle Tuxedo and Weblogic applications and host them within WebSphere Application Server."
