SQL Server maintenance

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.

Using sp_server_diagnostics

January 19, 2017 by

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. We could for example, use the results of various DMVs to look at wait statistic and resource information to help us focus our investigation in a particular area of SQL Server.

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.

Perform volume maintenance tasks security policy

April 4, 2016 by

Introduction

You may see it more commonly referenced as Database Instance File Initialization (DIFI). If you are not familiar with the file initialization, this is the process SQL Server has to go through when it is creating the data files for a given database, and also during an expansion event (either manually or from auto growth) for a database. It only pertains to the data file(s) of the database, as log files are not affected by this security policy. SQL Server will “zero out” the file, basically fill it up with a bunch of zeros to allocate the amount of space requested. If you are a new DBA, this configuration actually goes all the way back to SQL Server 2005.

How to execute jobs on multiple SQL Servers

February 18, 2016 by

Introduction

In earlier chapters, we explained how to administer multiple servers using the ApexSQL Backup and how to run queries in multiple SQL servers using the SQL Central Management Server. In this new chapter, we will show how to propagate a job from a SQL Server Master Agent Job to a target server.

This feature is called Multiserver Administration. In a multiserver administration, you need a Master Server and one or more target servers. In the master server, you create a copy of the job and then it is copied and executed in the target servers.

How to run multiple queries using the Central Management Server

January 25, 2016 by

Introduction

When you have thousands of SQL Servers, it is very hard to administer all of them. These article, will show some tips to help you on these types of tasks.

In other article, we showed how to backup a database on multiple SQL servers at the same time using ApexSQL Backup. In this new article, we will show how to run T-SQL scripts against multiple Servers using SQL Server Management Studio (SSMS). To do this, we will use the Central Management Server. The main idea of this feature is to administer multiple servers in a centralized way using queries or policies. This feature is available in SQL Server 2008 or later versions and cannot be applied in older versions.

Removing the risk from important maintenance tasks in SQL Server

January 18, 2016 by

As database professionals, we are often in very close proximity to important processes, data, and applications. While we adopt the mantra of “Do no harm”, many maintenance or reporting tasks that we create carry unseen risks associated with them.

What happens when a drive fills up during daily differential backups? What if an index rebuild job runs abnormally long and interferes with morning processing? How about if a data load process causes extensive resource contention, bringing normal operations to their knees? All of these are planned events, yet can cause considerable disruption to the very processes we are trying to safeguard.
