WebSphere Migration Workshop

by Roman Kharkovski

Frank Golazeski from the IBM WebSphere Competitive Migrations Team wrote an article about the new “WebSphere Migration Workshop”.

QUOTE: “One thing is to recognize the business need for a change, and another is to have the guts to do it. Even after the CIO recognizes the business sense in the migration effort, the rest of the IT team needs to be brought on board. This is where the IBM Migration Workshop can help. IBM has migrated hundreds of Oracle customers from WebLogic to WebSphere — with minimal disruption to their business. We’ve taken that experience and have packaged it into a free one, two, or three day class room experience that’s designed to ease the fear– both technical and emotional — that might hinder a migration…” ENDQUOTE.

How to cut your WebLogic license and maintenance costs in half?

by Roman Kharkovski

 I recently worked with an Oracle customer in Northern Europe helping them to replace WebLogic with WebSphere. You might ask why would a Fortune 500 company with significant existing investment of time, skills and money would decide to move off WebLogic? In this and many other cases high cost of WebLogic support and new license cost was such a powerful motivator that CIO decided to uproot their established environment and move it off WebLogic. Indeed, this has become a common pattern among former BEA and current Oracle customers. Since Oracle acquired BEA in 2008 there were a number of changes that WebLogic customers had to deal with. Most of these changes had to do with the way Oracle decided to price and license WebLogic Server and other BEA software. One example of such change is the Oracle license policy for VMware and other hypervisors. This article describes the licensing and pricing changes Oracle introduced to ex-BEA customers.

Oracle Service Bus review by Oracle customer

by Roman Kharkovski

I always thought Australians have a good sense of humor and this article is just another proof for it. This is a must read for anyone evaluating Oracle Service Bus – published little over a year ago, but the latest version of OSB has not changed much and most of the experience described in the article can be had now if one so desires:

QUOTE from the blog:
“…Ever heard the joke about regular expressions: Once upon a time a programmer had a problem. He decided to solve it using Regular Expressions. Then he had two problems. Welcome to my world (with an OSB flavour) :-) . I’ll try and capture a few thoughts and experiences below. It is very rare that I react so strongly against a technology… Can’t really think of another example. I’m usually pretty gung-ho and even suffer from odd breakouts of evangelical fervour. I can even find a place for UML in the nerd-ish pantheon :-) For this product all bets are off. I’m struggling to find a silver lining in the cloud…

… OSB has an “everything is XML” approach (OK I acknowledge that it’s slowly divesting itself of this, but there’s a way to go yet before the alternatives are anything approaching useable). I like XML as much as the next guy, probably more; it’s a great interchange format, but requiring it for all internal channels as well is a bit much: one ends up touching the in-flight data (translating/extracting/recomposing) too many times…

…an OSB proxy created to service a JCA adaptor is extremely fragile: changes to a database table requires a regeneration of the adapter files (or more like a recreation from scratch…manual click, click, clickety, click). Any slight change to an adapter forces a regeneration of the associated OSB proxy…which blows away any business logic (== pretty drawing) associated with the message flow. One is then forced to recreate the flow from scratch by hand (more manual click, click, clickety, click). Ghastly. Tedious. Error prone. Nonsense. It’s in the nature of the systems integration task that changes happen often. One gets tired of (re)drawing OSB’s pretty pictures very quickly, let me testify…” END QUOTE.

IBM and Oracle software licensing and support in virtualized private cloud environments

by Roman Kharkovski

Oracle license and support policy does not allow companies to take advantage of the server partitioning and imposes high costs practically negating many benefits of virtualization. IBM embraced virtualization years ago and provides support and flexible sub-capacity pricing for its customers. In 2010 Larry Ellison decided that “clouds are ok”. Since that time Oracle embraced both virtualization and private clouds at the “buzzword level”, yet Oracle license and support policy has not caught up yet and punishes Oracle customers who are using virtualized environments. How can there be such a disconnect between the marketing machine and the company legal and support policy?
