The Office for Work and Pensions (DWP) has successfully shifted its Job Seeker’s Allowance Payment Process (JSAPS) from its mainframe to an X86 architecture operating on Purple Hat Enterprise Linux — a mammoth job involving reams of legacy code, some of which was written in the nineteen sixties.
The re-platforming concluded with the remaining migration of fifty four databases that contains six.three billion documents from the initial databases/s to a “leading modern relational databases administration system” in below 24 hours
JSAPS (released in the late nineteen nineties) was based mostly on an IT code set that had been created in the nineteen sixties, with code added about the a long time as new specialized and policy demands modified. It has about 50,000 close end users. The substitution method involves 7.2 million lines of code, and 29,592 batch procedures.
That is in accordance to IT agency Superior, which supported the DWP with the shift. The change has halved how prolonged it usually takes to system applications, Superior reported: the first total working working day of things to do on the new method was finished in two hours and eleven minutes as opposed to a prior five hours, making it possible for the DWP to challenge two hundred,000 particular person payments well worth about £53 million.
Mark Bell, VME-R Deputy Director at the Office for Work and Pensions reported: “This has been commonly recognised as a single of the ideal specialized achievements shipped by DWP Digital for several a long time and as floor-breaking towards broader field standards. It also enables us to make even more electronic enhancements to reward hundreds of thousands of British isles citizens.”
Tim Jones, MD of Software Modernisation, at Superior instructed Computer Business Critique: “The programme to shift DWP’s applications to a new system is aspect of a big modernisation initiative to safeguard and strengthen the programs responsible for a £170 billion of welfare payments per annum.
“The scale, complexity and value of the project is probably the most significant of its sort to adopt an automated re-system method.
To give an thought of scope of the project…
- The Job Seekers Allowance software is the seventh DWP’s software to ‘go live’ as aspect of a much more substantial programme of get the job done to decommission its mainframe which started off in earnest with Superior in August 2017.
- Each method gives a mission critical assistance and as this sort of has nationwide ‘critical asset’ position.
- C. 25+ Million Lines of Code transformed using an automated method
- All code successfully translated to a modern code set and a modern built-in enhancement atmosphere (such as a big language translation for critical code)
- The migration of nine billion info rows all transformed, loaded and confirmed
- Only three programs at the moment continue to be on the mainframe as the programme enters its remaining stage.
