Sascha Lorenz presents a short talk on a surprising finding: Microsoft's preferred ORM often runs more efficiently on PostgreSQL than on SQL Server. We'll examine why PostgreSQL sometimes optimizes EF workloads more effectively, compare execution plans, and discuss which index strategies make the difference.

Consider this a brief overview of Query Store: What is it? How to enable it? A couple of important settings Built in reporting Forcing Plans

Demo-driven session covering the benefits and key considerations of Contained Availability Groups, with insights from real-world projects.

Your role as a DBA is crucial, as a pivotal figure in the realm of Microsoft SQL Server. Your ability to monitor and analyze your server's performance and troubleshoot issues is essential, and it's what keeps the system running smoothly. One of the most effective ways to do this is by utilizing the built-in data collection, which records a wealth of information.

This session will delve into six collections (Logs and traces) that can provide valuable insights into your server's configuration, health, and performance. By the end of this session, you will be equipped with practical knowledge that will empower you to handle any SQL Server issue confidently.

• Default trace • SQL Error log • SQL Agent Error log • System_health • AlwaysOn_health • Telemetry xEvents

I will show you each one's default location, retention, and content captured. We will discuss how to access and interpret these logs and demonstrate how they can be used to identify and diagnose issues such as failed logins and deadlocks, the health of the Windows cluster and availability group, and schema changes. By effectively utilizing the SQL Blackbox, you can ensure the smooth operation of your server and maintain the highest performance and reliability.

Prerequisite: Familiarity with SQL Server administration

Goals: 1. Know the default location, retention, and content of the six built-in SQL Server logs/collections. 2. Know how information from these collections can be extracted for different troubleshooting scenarios and ensure reliable and highly available database systems.

For data practitioners, working with NULL is inevitable. Its odd nature can lead to bugs and unexpected results for even the most experienced data pros. We'll discuss what NULL is and isn't, why it needs special handling and consideration, and some best practices in SQL Server.

Software Architects choose tools and patterns with an eye toward cost, time, shelf-life, and standard features. Data API builder is not source generation — it's Microsoft's free Data API engine that exposes secure REST & GraphQL endpoints over SQL Server, Postgres, MySQL, and Azure Cosmos DB, whether in Azure, on-premises, or even in AWS or GCP. In this session, we'll discuss security & architecture options, and when to use GraphQL versus REST endpoints.

SQL Server has had the ability to run on Linux for a number of years now but what are the differences to running on Windows? What are the benefits of running SQL on Linux? Are there any?

The focus of this document is to highlight early threat detection by using Splunk Enterprise and proactively start a cyber resilience workflow in response to a cyberattack or malicious user action. The workflow uses IBM® Copy Services Manager (CSM) as orchestration software to invoke the IBM FlashSystem® storage Safeguarded Copy function, which creates an immutable copy of the data in an air-gapped form on the same IBM FlashSystem Storage for isolation and eventual quick recovery. This document explains the steps that are required to enable and forward IBM FlashSystem audit logs and set a Splunk forwarder configuration to forward local event logs to Splunk Enterprise. This document also describes how to create various alerts in Splunk Enterprise to determine a threat, and configure and invoke an appropriate response to the detected threat in Splunk Enterprise. This document explains the lab setup configuration steps that are involved in configuring various components like Splunk Enterprise, Splunk Enterprise config files for custom apps, IBM CSM, and IBM FlashSystem Storage. The last steps in the lab setup section demonstrate the automated Safeguarded Copy creation and validation steps. This document also describes brief steps for configuring various components and integrating them. This document demonstrates a use case for protecting a Microsoft SQL database (DB) volume that is created on IBM FlashSystem Storage. When a threat is detected on the Microsoft SQL DB volume, Safeguarded Copy starts on an IBM FlashSystem Storage volume. The Safeguarded Copy creates an immutable copy of the data, and the same data volume can be recovered or restored by using IBM CSM. This publication does not describe the installation procedures for Splunk Enterprise, Splunk Forwarder for IBM CSM, th Microsoft SQL server, or the IBM FlashSystem Storage setup. It is assumed that the reader of the book has a basic understanding of system, Windows, and DB administration; storage administration; and has access to the required software and documentation that is used in this document.
