Is your PDB state saved?

Is your PDB state saved?

This might save you a couple of minutes if you wonder how multitenant works in combination with Oracle Data Guard. The question I got was, is your PDB state saved after a switchover? The short answer is: Yes it is. No statements without proving them of course, so here we go. The primary database: I have the state of my pub always saved in my post creation script, but you can easily retrieve in what state the PDB will be…

Data Guard made easy

Data Guard made easy

Sometimes I hear stories about struggles to setup Data Guard correctly. It should not be hard. There are lots of ways which lead to a correct setup. Die hards prefer the manual or own scripted way. Other people prefer the point and click method in Enterprise Manager. But one way, which is very easy, and I don’t hear people speaking a lot about it, is using the Database Creation Assistant (dbca).

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…
