UoB ‘properly live’ on Oracle HCM/ERP Cloud

UoB Logo

Over the last 6 weeks the project that I’ve been working on for the last year – University of Birmingham – has gone live with their New Core programme.

New Core comprises a number of moving parts, but front-and-centre of it all is Oracle HCM Cloud and Oracle ERP Cloud. The reason I say ‘properly live’ is this isn’t one of those posts where someone says “we’re live” but it’s really only a part of (more...)

2019 Kscope – Seattle and the Event


Sometimes I worry that my event posts are very 'samey', however from the start this Kscope was different.

First the travel was without issue - worthy of a post on its own! Unfortunately others were not so lucky and I sympathise, but for me, this time it was excellent.

I had been to Seattle with Kscope before so it felt very familiar. Sadly I wasn't able to travel earlier and so missed the Community Day (more...)

2019 Kscope – My sessions and the joy of Mentoring


Last year Certus and Accenture had been working on a solution for government, part of our engage.gov offering.

The solution involves an extension to Oracle Cloud using both PaaS and Planning Cloud (PBCS).

I thought it would make a great  pair of presentations, looking at both the PaaS development and the PBCS components. We had partnered with Brovanture for the PBCS and I knew the consultant working on that component, Jazmin Ribeiro.

Jazmin was up (more...)

Managing API Gateway Costs with Oracle API Platform

The Oracle API Platform adopted an intelligent pricing model by basing costs on API call volumes and Logical gateway node groupings per hour. In our book about the API Platform (more here). We suggested that a good logical grouping would be to reflect the development, test, preproduction and production model. This makes it nice and easy to use gateway based routing to different environments without needing to change the API policy configuration as you (more...)

2019 OUG Scotland – I Learnt a Lot – A Coincidence – I think not



A bit late on this blog for the annual UKOUG conference in Scotland. I love the regional events, they cover a little bit of everything and give a chance for people to come together, learn and build local connections.


Polly Pervis from Scotland IS gave a great talk about IT in Scotland. How more local can you get?

Then there were 36 sessions over 6 streams. I had the privilege of presenting twice. Up first (more...)
