I’m pleased to share all my cloud posts on this page. As with all the other pages, posts are in chronological order.
Using Oracle Database Free in your devcontainer and GitHub Codespaces
Dev containers are pretty nifty when it comes to keeping your development environment isolated from the rest of your system. Quoting from the documentation: Development containers, or dev containers, are Docker containers that are specifically configured to provide a fully featured development environment. Whenever you work in a codespace, you are using a dev container…
Using Ansible to resize the root LV on Oracle Linux 9 in OCI
While preparing an upcoming talk at a community event I worked on some Terraform code I recycled. In a nutshell, I’m creating a virtual machine in Oracle Cloud Infrastructure using Oracle Linux 9. I’m fully intending to run Oracle Database 19.28.0 on that VM later. Rather than sticking with the default boot volume size I…
Identify driver details of your cloud VM’s block devices
While preparing a presentation for POUG 2025 I had a need to find out more about the block device driver in use on my system. I was particularly interested in the SCSI mid-layer and low-layer drivers. Unsure about these terms? I am referring to the Linux Storage Stack Diagram. It’s a great resource for anyone…
Oracle Cloud Infrastructure: establish a console connection to a Windows compute VM
You may occasionally run into issues with a Windows 2022 (or later) compute VM in Oracle Cloud Infrastructure (OCI) that require you to access the VM via the graphical recovery console. This article describes how to connect to a graphical recovery console, based on VNC using MacOS 15.3 Sequoia. The latest MacOS 15.3 ships with OpenSSH_9.8p1/LibreSSL 3.3.6. It…
Use Flashback Time Travel with Autonomous Database
This is a very short post, mainly for my own benefit, to summarise how to use Flashback Time Travel (previously named Flashback Data Archive or Total Recall) in Autonomous Database 23ai – Serverless (ADB-S from now on). At the time of writing the database was patched to Release Update 7: SQL> select 2 version_full 3…
Containers are awesome, not only for stateless things
This post describes why using containers, even for database driven applications, is very useful.
Troubleshooting the Oracle Cloud Infrastructure API
Sometimes, it can be interesting to learn how the Oracle Cloud Infrastructure (OCI) API works, particularly if your favourite Internet search engine fails to locate the exact syntax of an API call. This is typically due to unspecific search terms because the OCI CLI is really well documented, but those things happen. I would like…
Enable the MongoDB API on Always-Free Autonomous Database
Oracle Database API for MongoDB translates the MongoDB wire protocol into SQL statements that are executed by Oracle Database. It lets developers who have MongoDB skill sets write JSON document-store applications for Oracle Database that use drivers and tools that understand the MongoDB protocol – which is way cool! If you would like to get…
