Day 11 of the Oracle Linux Basic Administration Series – Configuring and Securing SSH Access Welcome to Day 11 of the Oracle Linux Basic Administration Series! Today, we move into one of the most critical parts of system administration, securing remote access with SSH (Secure Shell). SSH is how administrators safely connect to remote servers, and securing it properly is essential to protecting your system. In this post, you’ll learn how to: Install and enable SSH on Oracle Linux Configure key-based authentication (passwordless login) Harden SSH settings for better security Change ports, disable root login, and limit access by user or IP Use the firewall to restrict SSH traffic These are the same steps used in real-world server environments to prevent unauthorized access and reduce attack risks. 👉 Read the full post: https://lnkd.in/eiDsj-9w Follow along daily! each topic builds on the last to help you grow from Linux beginner to confident system admin. #OracleLinux #LinuxAdministration #SysAdmin #SSH #ServerSecurity #LearningSeries #BlogSeries #LinuxForBeginners #TechForStarters #DevOps #SystemAdmin

Conceptual Gravity is very inspirational for those working on knowledge representation and processes related to various management tasks applied to #genAI architectures. The #NLP and #ML community is quite familiar with vector spaces and hyperplanes. Representation tasks and dimensionality reduction with Singular Value Decomposition (#SVD, #LSI) can be seen as space and field manipulations. In our agentic architectures at UC San Diego, the knowledge representation and management analogy proposed by Vince Kellen, Ph.D., in the "Metabolism of Thought" uses a biological perspective. The underlying representations in #AI and biology have geometrical properties relevant to this discussion. The embedding vector space or internal linear algebra in neural networks would require a more extended discussion. However, the field concepts and spatial distortion make direct sense when we look at knowledge graphs. For example, essential concepts in a graph might be surrounded by stronger "fields" and attract more "attention" from other nodes. Spatial distortions or waves can certainly augment the idea of searching a data structure as a geometrical proximity problem in the presence of fields with topologies, as an addition to "hop counts" or connection counts.

In large Oracle estates, cost creep usually comes from: – fragmented support across modules – upgrades postponed because they feel risky – implementations that don’t transition cleanly into run-state – different vendors for build, operate, and change The result: higher effort, slower change, and rising support costs.

"Exadata" is engineered database technology working closer to where data is stored. This video catches the feeling very well when Oracle's 400k customers are moving to the cloud with their mission critical databases and where performance, availability and cost are extremely important parameters. 🤣 Oracle Exadata can now be provisioned in all major hyperscalers (OCI,AWS,AZ,GCP) and AI capabilities are built in.

When I look back at Oracle 9i days, Database Administration often meant long nights, manual tuning, and countless scripts to keep things steady. The Database was powerful — but demanded equal power from the DBA. Fast-forward through 10g, 11g, 12c, and 19c → We saw Oracle steadily shift gears and Over Two decades, Oracle has quietly shifted the focus: ➡️ From complexity → to simplicity ➡️ From effort → to efficiency ➡️ From control → to accessibility Now with Oracle 19c and 23ai, the narrative feels complete in many ways: 👉 Less about managing the database, more about leveraging the database. 👉 Less about fixing issues reactively, more about anticipating and preventing. 👉 Less about how the data is stored, more about how quickly value can be extracted. To me, this evolution is not just about technology but about how Oracle has transformed the role of the DBA — from caretakers of data to strategic enablers of innovation. It’s fascinating to see how two decades of progress have made the Oracle Database not just bigger and faster, but also simpler, smarter, and more accessible.
