In my previous Blog I wrote how to install and configure SUSE Manager. In this Blog I will go more in the deep like repository management and PXE boot configuration. Configuring repository To syncronize products from SUSE repository, you need configure first the Organization Credentials. To get your username and password for repository you need to go: https://scc.suse.com/ Login with your SUSE Account Admin -> Setup Wizard -> Organization Credentials -> Add a new…
By Franck Pachot . In a recent tweet I wanted to highlight the importance of knowing what you measure with pgbench, because looking at “Transactions per second” without knowing if you are in shared buffer cache hits, or filesystem cache hit, or storage cache hit, or physical read… is just meaningless: When you run the #postgres builtin pgbench, you should know: – the size of the dataset on disk, about 15MB x scale – the…
In this Blog I will write the requirements and steps to install SUSE Manager Server. Maybe you heard about SUSE Manager but you could not understand why a SUSE Manager Server (SUMA) can help to manage your server environments easier. How can SUMA help you? Without automated processes, the systems management overhead increases, and this leadS to increased costs. Get a complete hardware and software inventory of your systems. Install Software with few clicks to…
By Franck Pachot . The Linux metrics that are usually considered for performance monitoring and troubleshooting have many drawbacks and frequent misinterpretations. The recent kernels provide PSI (Pressure Stall Information) which is not enabled by default in Oracle Linux “unbreakable” kernel. However, the kernel is compiled with it. Here is how to enabled it in a newly create Autonomous Linux instance (the Oracle Cloud Linux ,based on OEL 7.9, with no-downtime patching) Check PSI availability…
My Background Since I started at dbi services sa (before 3 Weeks), I was working and preparing for the SUSE Linux Enterprise 15 certification. I had worked with other Linux distributions like CentOS, Ubuntu and Debian on my old employer. With my basic Linux knowledge I was able to administrate Apache and nginx with virtual hosts, SSL Encryption with Let’s Encrypt, installing and configuring MySQL Database, opening/closing ports for services with firewall-cmd, network configuration and…
By Franck Pachot . Oracle Enterprise Linux (OEL) is a Linux distribution which is binary compatible with Red Hat Enterprise Linux (RHEL). However, unlike RHEL, OEL is open source, free to download, free to use, free to distribute, free to update and gets free bug fixes. And there are more frequent updates in OEL than in CentOS, the free base of RHEL. You can pay a subscription for additional support and features (like Ksplice or…
By Franck Pachot . I used to have many VirtualBox VMs on my laptop. But now, most of my labs are in the Cloud. Easy access from everywhere. GCP There’s the Google Cloud free VM which is not limited in time (I still have the 11g XE I’ve created 2 years ago running there) being able to use 40% of CPU with 2GB of RAM: top – 21:53:10 up 16 min, 4 users, load average:…
As discussed in a previous blog, working with LSS might prove a little bit challenging from time to time. In this blog, I wanted to share an error I saw while installing LSS 16.6.1 on an Oracle database. Initially, I developed my silent installation for LSS (while encapsulate the LSS silent scripts provided by OpenText) using a PostgreSQL database because it’s usually easier to setup an environment on Kubernetes with PG because of licenses. …
Oracle Database Appliance (ODA) is by default configured with software raid for Operating System and Oracle Database software file system (2 internal SSD disks). 2 raid devices are configured : md0 and md1.ODA are configured to run raid-check every Sunday at 1am.
Last days, I needed to test our DMK tool for the new MySQL and MariaDB releases on the most recent version of CentOS. Here you can find all important steps to configure a CentOS 8 VM with an Internet connection, a specific hostname and a static IP address, accessible through SSH on VirtualBox.
