Jason's Blog on Oracle Modernization Solutions

I was recently visiting a customer in Latin America discussing what a target architecture would look like given that some of the code would migrate over 'as-is' in Cobol, and some new work would be done in Java, while at the same time, the 'new' system would need to integrate with existing mainframe technologies.

This is a combination of both WebLogic (for Java) and Tuxedo (for the rehosted Cobol) as well as our SOA Stack for integration and new Business Processes. Below is an excellent slide that Mark Rakhmilevich recently provided on what this target stack looks like.

You can see in this picture, we have the various layers all built on 11g Grid Technology.
The Oracle technology stack starts with the database grid, which is the cornerstone for data management. The next layer up is Application Infrastructure comprised of Oracle Tuxedo and WebLogic, which are two application platforms in OFM that host business logic – Tuxedo hosts re-hosted COBOL and C/C++ and WebLogic hosts Java for extended services, new components, etc. Both provide high degree of SOA capabilities and integrate with the Oracle SOA Suite technologies shown in the Services Infrastructure layer, and standards-based service networks. These technologies together enable re-host, expose, re-architect, extend, and re-use approach that we've gone over in this blog.

SOA Enablement and Integration of the Mainframe is a topic which is taking a lot of my time these days. Everyone wants to Integrate in the real time with IMS, DB2, Adabas and other systems to Oracle. Also, (like we mention in the book) this is also a great way to open up mainframe processes for BPEL Orchestration.

So, let me take some time to promote an event that HP is doing in Vegas in June. My partner in crime Tom Laszewski, is giving a session called Service Orientated Mainframe Modernization using Oracle Fusion Middleware (ession ID:3007 / Title: Service Orientated Mainframe Modernization using Oracle Fusion Middleware)

Tom works in PTS (Platform Technology Solutions) with me on the Modernization team at Oracle. He is our resident guru on all things SOA, and you don't want to miss this. He'll talk about real-world SOA Enablement projects from Data, Business and UI Tier integration.

In the world of Modernization, there are many options. It isn't just COTS, Rehost or Re-write. They are all valid citizens on the world of Modernization. SOA Enablement is one that I see quite a lot and is sometimes (more often than not) a first step in any modernization, and is usually done along side any option you choose.

So...go.
