September 19, 2017 by

Database migration is a vital task in any environment, complex or otherwise. Seamless migrations are the goal but the efforts required to ensure it are tremendous.

Backing up and restoring the database is surely a preferred and a robust approach, but does it work well in all situations? How do we plan this when the source and the destination databases need different configurations? How do we make such a migration seamless?

How to replace hardcoded lookups using SQL Server Master Data Services

September 14, 2017 by

Introduction

A big part of the technical debt in my organization’s data warehouse (DW) and business intelligence (BI) environments relates to hardcoded lookup data. This is data required by the business to make sense of transactional data but was never planned for in the underlying source system and consequently get injected into DW and BI solutions. Inevitably, it is only a matter of time before DW and BI team lose track of the places wherein the hardcoded data reside thus making it difficult to maintain. Furthermore, due to lack of documentation or staff retention, anyone who subsequently takes over these DW/BI solutions can unknowingly create duplicate lookup data. In this article, I explain how we reduced such technical debt in my organization by moving most of the hardcoded lookups into SQL Server Master Data Services (MDS).

Synchronizing SQL Server Instance Objects in an Availability Group

September 8, 2017 by

Availability groups can no longer be considered new. The feature was released in SQL Server 2012 but I often notice that SQL Server Failover Cluster Instances (FCIs) are much better understood. For a very long time, when people thought about SQL Server they thought about the entire instance as a unit. Microsoft has been implementing new features and services which begin to segment the concept of an instance from the concept of a database.

Introduction

Let’s say we have a database role that we don’t need anymore because we defined another security policy using another database role. What are the steps to follow in order to properly drop this database role? That’s the question this article will try to answer, covering as many cases as possible.

How to use Microsoft Assessment and Planning (MAP) Toolkit for SQL Server

March 31, 2017 by

As a Microsoft SQL Server Database Consultant, I have to visit multiple companies with variety of SQL Server versions and patch level. Generally speaking, we need to analyze the environment of these clients and get information about the infrastructure. To do so, we have to run multiple scripts and tools on almost all the machines at client. Though it’s a part of our job but at times it takes hours to get even the basic information about the SQL Server versions, patch level, configuration and small details which even client does not have.

Troubleshooting SQL Server is all about gathering the right evidence. Ordinarily we utilise a variety of different methods and analyse their output to look for specific areas where we would focus our diagnostic efforts.

How to build better alerting

May 4, 2016 by

Background

One of the most popular complaints from developers to DBAs involves alerting, whether from third party tools or alerting built by other developers or DBAs in the environment. Building or using alerts for important applications, data layers, or processes within a SQL Server environment offer everyone benefits, but can become noisy if they’re architected poorly, or the purpose isn’t considered. In this article, we look at considerations for building effective alerts that tell us when something is wrong without creating situations where we learn to disregard them. We want to make sure that we respond when we need to, and not always be on high alert when there is no issue.
