Have you been working with Oracle DBMS for a while, or just started discovering its features? Regardless of your level of expertise, there are always plenty of things to learn about Oracle since it’s one of the most popular DBMSs for handling large-scale databases and empowering enterprise-level applications.

When it comes to database performance optimization, database administrators or developers must understand the differences between blocking and deadlocks in SQL Server because these concepts often need clarification. Blocking and deadlocks help handle access to shared resources when working with concurrent transactions. However, improper management or a lack of awareness about their behavior may lead to performance issues, such as failures and delays in processing transactions.

Ensuring seamless data flow and robust application performance is crucial in modern networking and cloud computing. Traffic mirroring enables enhanced network observability, allows for effective troubleshooting, and facilitates the testing of new features without interrupting live traffic. It captures and replicates network traffic, providing a powerful solution for maintaining and optimizing network operations.

Reliability testing is ongoing work, and tracking that work can be difficult in large organizations. Engineers run one-off experiments, scheduled Scenarios run in the background, and, for more mature teams, CI/CD workflows fire off automated tests on demand. According to our own product metrics, teams run an average of 200 to 500 tests each day! With so much happening, it’s hard to keep track of everything going on in Gremlin—until now.

Docker is a helpful tool for application management. You can use Docker in various ways: in the standalone mode, using Docker Compose on a single host, or by deploying containers and connecting Docker engines across multiple hosts. The user can use Docker containers with the default network, the host network, or other more advanced networks like overlays. This depends on the use case and/or the adopted technologies.

This series of blogs, Monthly Module Mondays, started on April Fool’s Day 2024 discussing how to Inventory and remediate Red Hat Enterprise Linux with Security Technical Implementation Guides (STIGs) has now reached the 10th installment showcasing a couple of modules to take stock of what services are running on your systems.

Editor's Note: This post originally published May 2024. It was updated January 2025. In today's fast-paced world, the unexpected is always around the corner. Imagine an associate suddenly slips off a ladder in your retail store during the holiday season while it’s buzzing with activity. Would they be able to call for help? If not, someone needs to be notified, especially if customers or other associates don’t witness the fall or notice the injured associate on the ground.

Handling logs in a large-scale server infrastructure is no small task. It’s a critical component of maintaining smooth operations, especially for industries like healthcare, where over 1,000 servers might be managing everything from patient records to billing systems. When these logs are scattered and disconnected, this disarray slows troubleshooting, fragments operational insights, and ultimately undermines system reliability.
