Review SQLdays: Keynote SQL 2025 – Thorsten Kansy

Review SQLdays: Keynote SQL 2025 – Thorsten Kansy

07.10.25 Thorsten Kansy SQLdays Konferenz English Version Als Thorsten Kansy 1993 mit SQL Server 4.2 loslegte, war das der Beginn einer langen Reise durch Features, Trends und gelegentliche Irrwege. SQL Server war – wie Thorsten so schön sagt – “ein Kind der Zeit”. Was gerade hip war, wurde eingebaut. Was sich später als Irrweg entpuppte, wurde… naja, irgendwann wieder entfernt oder ignoriert. Dann kam JSON. 2016 wurde es halbherzig eingebaut – als VARCHAR. Ein paar Funktionen, aber keine echte Liebe….

Power BI Report Server: Handling Agent Jobs in an Availability Group

Power BI Report Server: Handling Agent Jobs in an Availability Group

Deploying Power BI Report Server in a SQL Server Availability Group (AG) is a great way to boost resilience and uptime. But there’s a catch: Power BI Report Server itself isn’t AG-aware. That means when a failover happens, things can get messy—especially with SQL Agent jobs. The Problem with Failover When the AG fails over to a secondary node: The Fix: Add a Primary Check Step to Agent Jobs To avoid this, you can add a check step to each…

Troubleshooting “Service Unavailable” and URL Reservations in Power BI Report Server

Troubleshooting “Service Unavailable” and URL Reservations in Power BI Report Server

Running into a “Service Unavailable” error when accessing your Power BI Report Server? You’re not alone. This issue can be frustrating, especially when everything else seems to be configured correctly. One common cause is incomplete URL reservations in http.sys. This is especially relevant if your Report Server is set up to respond to multiple addresses, like in a scale-out deployment or an Availability Group setup (see my previous post: Power BI Report Server: Managing Multi-Homed URLs in an Availability Group…

Power BI Report Server: Managing Multi-Homed URLs in an Availability Group Setup

Power BI Report Server: Managing Multi-Homed URLs in an Availability Group Setup

Running Power BI Report Server in a high-availability setup can be a bit tricky—especially when you want it to respond to multiple URLs. A common scenario is when the Report Server is installed on nodes that are part of a SQL Server Availability Group (AG). Why Multiple URLs Matter In this setup, each server should be reachable via its own hostname, but the primary node of the AG should also be accessible via the AG listener name. This ensures that…

Power BI Report Server: Checking Folder and Report Permissions with a Paginated Report

Power BI Report Server: Checking Folder and Report Permissions with a Paginated Report

Managing permissions in Power BI Report Server can feel like navigating a maze. Just like in Windows, you can assign permissions to folders or individual items, and you can even break inheritance at any level to redefine access. While this flexibility is great, it can quickly become hard to manage—especially in larger environments. Keep It Simple: Best Practices for Permission Management Here’s my recommendation: If you’re new to this topic, check out Microsoft’s documentation:Roles and permissions in Reporting Services –…

Monitoring Power BI Report Server Execution Status with a Paginated Report

Monitoring Power BI Report Server Execution Status with a Paginated Report

Keeping an eye on your Power BI Report Server jobs can be a bit of a black box—until now. To make monitoring easier, I’ve built a paginated report that lists all ReportServer jobs, including both automated data refreshes and subscriptions for paginated reports. Big thanks to P. Theriault for the error criteria inspiration and to Alexander Korn for laying the groundwork with the base view! What the Report Does The report pulls job execution data from the ReportServer database and…
