I am an Oracle dba started in Oracle 9i. I am currently working as a Senior Oracle DBA at Exitas NV . Check their twitter handle ( @Exitas_BE ) some nice things are shared through there as well. Most of the time I work on short term projects which put me in touch with a lot of different aspects of the Oracle database, going from infrastructural point to complete designs and implementations, the result of this is a nice allround experience and a broad personal network. Currently the focus is on Exadata/ODA and virtualisation on exadata. Exadata experience starting from X2 to X7 including complete reinstallation’s and redesigns of the environment. My main focus is to help the customer to find the best solution fitting in his budget and offer the maximum out of it given restrictions. That sometimes requires taking an exam. My most relevant badges are also here on my badges page at http://vanpupi.stepi.net/badges/. The bit of free time there is left, is mostly spent on being husband and a dad for my son. The time left I like to spend with sailing and playing the double bass, bass guitar and the saxophone. You can find me on twitter : @vanpupi or find me on about.me
Hello Data Guard!

Hello Data Guard!

When you have read my blog before, you notice immediately that this blog post is not technical at all. Sometimes in life, there are moments that unique opportunities cross your path. That happened to me to. 1st of Februari 2019 I have joined the mothership Oracle as Product Manager For Data Guard. First of all, I want to do a big shoutout to Exitas, my (now) former employer. I worked with them for more than 10 years and I enjoyed…

The Exa-guard project

The Exa-guard project

Ok I cannot name the customer (Approval pending) but a very exciting project just came to an end. You might be aware that I currently have a focus on exadata and high availability and sometimes nice projects come across your way. The title is an invented one, as it was a combination of looooots of exadata stuff and dataguard. And admit, it just sounds cool, isn’t it? 😉 The beginning The initial question was: “Can we expand our X3-2 non-prod…

Keep it running, can you?

Keep it running, can you?

Recently I had a meeting at a customer with a very nice question. It was a kick-off meeting, but the question was … is it possible to have a system that gives us 99,999 or 99,9999 uptime for our Oracle database. My first reaction was, “But can your stack on top handle these requirements as well?” Apparently they already have this, so now it was time to put this on db-level too. I have to say that the MAA-team does…

ODC Appreciation Day : The Oracle Community

ODC Appreciation Day : The Oracle Community

This time I don’t want to say thank you to a particular Oracle Feature, but I want to highlight the entire Oracle Community. It started a couple of years ago. After a nice project implementing OVM on Exadata, Philippe Fierens convinced me to start speaking at conferences. Since then, I did not regret any second of that decision. The Oracle Community is such a warm group of people. The cool part is, you don’t have to be shy! Everyone makes mistakes…

OCI-Tenant admin locked, how to reset your own password

OCI-Tenant admin locked, how to reset your own password

There are some of those days that you rely too heavily on password tools. Yes, you always should use different passwords and strong ones. But I won’t preach to you, but due to this, I locked myself out of my tenant admin user in the Oracle Cloud Infrastructure (OCI). For those who have seen my OCI – talk already, you know I’m a big fan of the OCI – utility. Also a comprehensive list of things you can do with it,…

lab-time: upgrading grid infrastructure (gi) from 12.1 to 18c – the final version

lab-time: upgrading grid infrastructure (gi) from 12.1 to 18c – the final version

In an earlier blogpost, I was playing around in an unsupported way to upgrade my lab Grid Infrastructure from 12.1 to 18c. The problem there was, that the 18c software was not officially available for on-premises installations. Now it is! During my holidays I had a little time to play around with it and this is how I upgraded my cluster. Reading the documentation it seems very easy (and it really is). Unzip the software and run gridsetup.sh. I wouldn’t…

Exadata Security: the joy of PXE and UEFI: Secure boot violation

Exadata Security: the joy of PXE and UEFI: Secure boot violation

Today I had the honour to join my colleague Freek D’Hooge (find him here: @dhoogfr )in the datacenter. Task for today, reimage an 1/8th X7 Exadata using PXE. Andy (Colvin) warned me already that, when trying to reimage them, they are now using UEFI – boot. Knowing this in advance, this would be an #exatastic day. As usual, Andy was right. Trying to boot one of the cells on the pxe “the old method” resulted in: “Secure boot violation: Invalid signature…

Tunnelblick ovpn client for Mac os High Sierra

Tunnelblick ovpn client for Mac os High Sierra

This weekend I was playing around with Openvpn to a new site. I use Tunnelblick for this, but this time was the first time after I had upgraded my Mac to High Sierra (10.13.5). Suddenly my vpn connections didn’t want to load anymore. Tunnelblick threw these errors to me:

I was running a beta, so first thing was to install the stable release, but the message remained. This link: https://tunnelblick.net/cKextLoadError.html helped me. In high sierra to use or add modules…

Building bridges: “Bridge must not have discovery mode for LACP interface; Interface file: bondeth0;”

Building bridges: “Bridge must not have discovery mode for LACP interface; Interface file: bondeth0;”

Some days start as an exatastic day and end up grasping your hair. This post is about such a day. A brand new shiny X7 Quarter Rack exadata was being installed for a customer. This setup was a fairly straightforward one. Quarter rack, full ovm and 2 virtual clusters. Not too fancy. LACP is being used for the public network on the fibers and vlan tagging is done on the switch. Given that, my customer created a OEDA configuration using…

A heads up for my bad memory

A heads up for my bad memory

Gotcha! This post is not about memory settings at all, but a quick heads up. If you are dealing with several generations of exadata’s and you like ironhugging them as much as I do, sometimes things can get confusing. The X7 exadata has changed a bit so when you use them, it’s nice to do things right. Only way to do it right is check it, double check it and verify. One of the things which is always in my…
