2017OOW – ACE Director Briefing

This year the ACE Director briefings were a little bit different.

There was a single day of content, and as we walked to HQ, I guess we were all worried that we were walking towards our own execution. There had been a number of changes to the program which sometimes looked as if funding was being cut or more difficult to get, and with the creation of the new Developer Champions Program; were we on (more...)

2017OOW – Travel and Hotels

It may just be me, but my travel could be a soap opera; there are always challenges and frustrations. During my trip I have been told I am very British and underplay challenges, so what I actually mean is you need to be a relaxed person or have your own techniques for surviving.

Twitter may be my technique, nothing like a public rant to let off steam!

Complaining is also a very British pastime. 


2017OOW – EOUC Short Talks

I wrote a lot about these before the event, and gave statistics based on pulling it together.

On the day, I always worry, will the technology be up to it? But most of all will people turn up for it?

This year, Oracle 'hijacked' User Group Sunday with 'complimentary content', and then the session before us was moved with just 10 minutes notice because one of these sessions had a larger number of (more...)

Oracle Linux: How to change from uek to Red Hat compatible kernel

After a standard installation of Oracle Linux the uek kernel is bootet by default (unbreakable enterprise kernel).
# uname -a
Linux localhost.localdomain 4.1.12-94.3.9.el7uek.x86_64 #2 SMP Fri Jul 14 20:09:40 PDT 2017 x86_64 x86_64 x86_64 GNU/Linux
This behaviour can be changed with these commands:
First you have to get the linenumber of your new target kernel:
# grep ^menuentry /etc/grub2.cfg  | xargs printf '%s\n' |grep Oracle

Update on the Family Tree

The Oracle Family has grown, we have adopted a new son, Gerald Venzl.
If you don't understand, the fun Oracle Family here is the original story.

This was Tim's idea, although I am 100% behind the decision, I was shocked as we had decided that Heli (from Finland) was more than enough.

So here is a new family tree because even we are confused. In fact Maria is very confused and thinks that makes Gerald (more...)

JDK 9.0 released! (but java.net is gone)

Some week ago, i downloaded jdk 9 via java.net. But this page in not available anymore:
After some searching i found the download page for the jdk: http://jdk.java.net/9/  (so java.net is not really closed...). But it is easier to download them from the official Oracle website:

$java -version

Java(TM) SE Runtime Environment (build 9+181)
Java HotSpot(TM) 64-Bit Server VM (build 9+181, mixed (more...)

As every week I was also updating the following two lists with the (more...)

The Fishbowl Team Wins the 2017 Modern CX Hackathon at Oracle Openworld

The Fishbowl hackathon team headed out to San Francisco on Friday September 29th with Chatbots on the brain.  Their goal was to develop a solution that would improve sales productivity and margin as well as to improve executive insights and information access by allowing 24/7 conversational access to a sales pipeline.  And so the sales assistant chatbot was born.

The team spent the following 2 days writing code, utilizing Oracle’s cloud based services, (more...)

IOT on #oow17 and in my life

Last Sunday i attended an interesting session at #oow17.

It was a session about how Federal Express, an American Company who delivers parcels, used the electronics in cars that monitor tyre pressure, a lot of parameters from the engine and the gps of the car to collect huge amounts of data. With this data they could coach drivers to drive more fluently to save fuel and prevent excessive engine and tyre wear. They saved (more...)

Oracle 18c: self-driving, self-scaling, self-repairing AND documentation-free (?)

Yesterday Larry Ellison announced Oracle 18c:
After 12c now 18c?
Why 18 and not another number greater 12?
Inside a whitepaper released with the announcment the version 18c is not named at all.

The whitepaper just contains some high level information about the autonomous database:

and some licensing information:
But no real information about this new database 18c.
If this new database works like promised:
Fully automated patching, upgrades, backups, and availability architecture perform (more...)

Oracle DB 12.2 on Oracle Linux: Preinstallation tasks and Installation

Virtualbox: How to use shared folders (aka gemeinsame Ordner)

If you want to use a directory inside a virtualbox vm without copying all files, you can use the shared folders.
Just choose a folder to share:

Then inside the vm type:
[root@localhost oracle]# mount -t vboxsf 12c /mnt
and that's it:
[root@localhost oracle]# df -h |grep 12c
12c                  180G    129G   52G   72% /mnt
[root@localhost oracle]# mount | grep 12c
12c on /mnt type vboxsf (rw,nodev,relatime)

When you are done just unmount the folder with
umount /mnt

Running Oracle Linux inside VirtualBox: Installation Virtualbox guest additions

My In-Memory Skills – Being a column rather than a row

Recently I have been thinking more about my skill set. 

I step down from the UKOUG board in March and the appointments board who are looking for candidates have asked what skills are needed and I am trying to articulate those I have.

The question about 'what I actually do?' is often asked:

Just last night I was speaking to a senior customer and an Oracle Account Manager introduced me as Certus' "Face" (more...)
