As I mentioned on another post, I doubt they want to pay for a complete rewrite of the mainframe application. I think they want to port to CICS on RS6000 to save money, and that means they probably can't afford a completely new custom application. They might be able to use a VSAM emulator on CICS/RS6000 or convert the application to DB2 running under CICS on RS6000. I don't know if Oracle works with CICS on RS/6000.

I would probably stay on the mainframe until they find a packaged application that runs on a distributed platform. This may require that the company change parts of their business process to fit the package, but that is what I would do. If they don't want a new application, I would stay on the mainframe.

The odds of a medium scale application development project ever being completed with code in production is less than 50%. Of the remaining 50% that make it into production, the vast majority of those projects will be over way budget and/or seriously late to completion.

In a situation like this, picking the DBMS product is not the first decision to be made. Received on Thu Feb 05 2004 - 08:19:07 CST
