Earlier this year I was asked by the Business Analysics & Big Data SIG (of the UKOUG) to give a presentation on Oracle R Enterprise. Unfortunately I had already committed to giving the same presentation at the OUG Norway conference on the same day.
But then they asked me if I could record a video of the presentation and they would show it at the SIG. The following video is what I recorded.

I've never been to KScope. Yes never.
I've always wanted to. Each year you hear of all of these stories about how much people really enjoy KScope and how much they learn.
So back in October I decided to submit 5 presentations to KScope. 4 of these presentations are solo presentations and 1 joint presentation.
This week I have received the happy news that 2 of my solo presentations have been accepted, plus my joint (more...)

Error in .oci.GetQuery(conn, statement, data = data, prefetch = prefetch, :
ORA-29400: data cartridge error
ORA-40024: solution to least squares problem could not be found
ORA-06512: at "SYS.DBMS_DATA_MINING", line 2153

It seems to be traditional for people to write a blog post that summaries their Oracle Open World (OOW) experience. Well here is my attempt and it really only touches on a fraction of what I did at OOW, which was one of busiest OOWs I've experienced.
It all began back on Wednesday 21st October when I began my journey. Yes that is 9 days ago, a long long 9 days ago. I will be (more...)

When attending conferences sometime you get to hear about a good presentation or some other (more...)
Over the past couple of weeks I've been preparing my slides and presentations for Oracle Open World (2015).
One thing that occurred to me was that there was no icon or image to represent Oracle SQL and PL/SQL. I needed something that I could include in my presentations to represent these.
After a bit of Tweeting it turns out that there is no (official) icons or images for Oracle SQL and Oracle PL/SQL.
So I (more...)

BICS stands for Oracle BI Cloud Service.
Over the past few months I've been (more...)
