Upgrading from RHEL 9.6 to 10.1 is not just a routine update, it’s a major platform shift. When your server runs PostgreSQL compiled from source and a Patroni-managed cluster, the complexity increases significantly. System libraries change, Python environments break, ICU versions evolve, and your database binaries may no longer start after reboot. In this guide, I walk through a real-world…
This tutorial showing simple database upgrade to 26ai using traditional method and autoupgrade tool, For operational databases please properly test and plan your upgrade. https://docs.oracle.com/en/database/oracle/oracle-database/26/fppad/upgrading-oracle-database-software.html This is one from 3 Articles related to 26.1 upgrade: Step 1. Downloading software and preparing Linux Download Base Gold image from Oracle support software from latest Oracle AI Database 26ai (23.26.1) for Linux x86-64…
To run a Perl script directly like a binary from within the shell, you have to the 2nd and 3rd example will run the script with the given Perl-binary. The 1st example uses the 1st perl binary found in $PATH If you work with Oracle and want to use a Perl script connecting to the database, then the Perl from…
The Documentum Interactive Delivery Services (IDS) doesn’t seem to be very popular, at least in my experience, as I haven’t seen that one used in a lot of situations. However, when I did, I always had to increase the IDS Memory, as the default JVM was never enough to process an actual production load. Memory configuration on Linux On Linux,…
In the last post about SUSE Multi Linux Manager we had a look at how you can schedule OpenSCAP reports using the API. In this post we’ll look into something very basic: How can you patch the server components of SUSE Multi Linux Manager. We speak about components because you need to patch the host (which is a SLE Micro…
As we’ve recently supported some customers on SUSE Multi Linux Manager I’d like share something which was not as easy to implement as it appeared to be in the first place. But first of all, what is SUSE Multi Linux Manager? It is basically a fork of Spacewalk which was also used as the upstream project by the Red Hat…
DMK is a Database Management Kit that can be used in various database environments. It simplifies command-line tasks for Databases Administrator on Unix and Windows systems. It supports multiple databases including Oracle, MongoDB, MariaDB, and PostgreSQL. It also includes additional modules for automating RMAN backups, database duplication, and database creation.dbi-services recently released version 2.2.0, introducing significant improvements for Oracle databases with RAC/ASM and enhanced support…
Before we explore Microsoft Defender & Arc, I must clarify: Setting up Microsoft Defender and Arc on a Linux server, especially one without internet access and with robust security monitoring and hardening, may seem counterintuitive. However, because the software was already purchased, managers insist on deploying the same product across all servers. So here we are, deploying a Microsoft closed…
In this Blog post I will try to give a pure technical cheat sheet using Btrfs on any distribution. Additionally I will explain how to use one of the most sophisticated backup/ restore tool called “snapper”. What is Btrfs and how to set it up if not already installed? Btrfs (aka Butter FS or aka B-Tree FS) is like xfs…
Once you have your OpenStack playground up and running it is time to actually use it. What we want to do today is to create our first compute instance. Before we can do that, we again need a bit of preparation. If you know AWS EC2, or other public cloud services when it comes to compute, you probably know the…
We’ve finished the last post with a working Network (Neutron) service on the controller and compute node. In this post we’ll setup the final service which is Horizon, the OpenStack dashboard. Once more, looking back at what we need at a minimum, we’ve done most of it by now: Currently, the overview of our playground looks like this: Today we’re…
We’ve finished the last post with a working Compute (Nova) service on the controller and compute node. While only the compute(s) actually run compute resources, Nova is also running on the controller for the management tasks, while libvirt is only running on the compute node. Once more, looking back at what we need at a minimum, we’ve done most of…
