Porting Apps? Downtime.. Eh
[quote]RBS faces a Herculean job in bringing online a new mainframe operating in a core part of its day-to-day business. It must plan and execute the job without interrupting the existing service by taking the old mainframe offline during the transition.
RBS did not say when it plans to bring the new mainframe online.
But hardware is only one thing: RBS must also determine what do with the existing apps running on the system. Either it must port existing apps to the new system - which is likely - or write or buy new apps. If the former, RBS must design, write, test and then shift. If the latter, RBS must make sure the new apps work on the new mainframe and interoperate with other RBS’s other, connected systems.[/quote]
Spoken by someone that knows nothing about mainframes. Are you a consultant by any chance ?
RBS are just buying a bigger mainframe and then plugging it into their existing parallel sysplex system. Whoop de doo. All that will get them is the chance to use the newest version of the bits of mainframe software and things will run a bit faster.
No porting of apps, no downtime required. That is what makes the mainframe such a great environement to develop and run. Something that lesser mortals dont get.
