Sven's humble thoughts about Oracle and tech
Once you are hosting an application in some environment, doesn’t matter if on-premises or in the cloud, you want to get notified by the application when soemthing happens or you need to take action. As an example let’s assume that may be a GitLab community edition you manage yourself in the Oracle Cloud Infrastructure. For this purpose there’s an Email Delivery Service which you can use to send mails from your cloud applications. For this to work you have to... » more
This year I had the possibility to attend the DOAG CloudLand for the first time and also had the honor to talk about an OCI migration project from 2023. Although I had a rather unpleasant time slot during lunch on the last day, the audience was quite intereseted. Of course I also attended quite interesting talks from other people. In general the topics were quite container centric and basic infrastructure or even Oracle software had to be looked for. So... » more
Maybe you have realized that when you deploy a compute instance in your favourite cloud environment that the “hardware” clock is set to UTC - which is the coordinated universal time. And that of course totally makes sense, since your cloud provider is operating a global business. That also isn’t a problem if you handle your times and dates in your Oracle database application properly with a timezone component. For this you can save time related data in the TIMESTAMP... » more
Recently I was playing around with the go programming language by google. Although I am not a fan of this company anymore for various reasons, the programming language is fun to work with. Especialy when it comes to development of CLI utilities it has quite some advantages and combines the ease of use like perl and the feature of producing a compiled binary like from C. Also I am a big fan of strictly typed languages. So I developed a... » more
Recently me and some of my colleages from Robotron visited the DOAG Database conference in Düsseldorf. I also spoke about Transparent Data Encryption and it’s little helpers on Oracle Engineered Systems. You may already have read about some of these in my blog in the past. I was happy that although during my speech nobody asked a question - which is kind of irritating since you can’t know if that’s out of misinterest or because you answered already everything -... » more
Terraform is a nice tool when managing infrastructures in your cloud environment. It becomes really powerful when it comes to mass deployment and managing resources where you don’t need to repeat yourself too much. I think many of us experienced the start of a project with singleton resources when we were bloody newbies. But as time passes by the need for a more scalable solution emerges and you need to transform that singleton into a more iterative manner of resource... » more
Oracle lately introduced the Oracle Database Appliance Software Release 19.22 with the usual fixes and updates to all of it’s components. It also provides an eagerly awaited fix to the included ASR manager, so now you can use that again. But where’s light, there also may be some shadow. If you are using a newer version of PuTTY on Windows, a recent version of OpenSSH on macOS, you might get the following errors after patching the system to 19.22. macOS... » more
I am happy to announce that I will be appearing at least at two conferences organized by DOAG, the German Oracle user group. The first talk will be held at the DOAG Datenbank 2024 and the topic is Transparent Data Encryption auf Engineered Systems - Kleine Helfer which is about TDE and their helpers on engineered systems on premises and in the OCI. I love this conference in Düsseldorf and am happy to be there again. The second appearance will... » more
