Before then, there were two approaches to storing unstructured data in SQL. DB file. I would estimate that for every time Ive had to deal with an emergency restore, including point in time restores using transaction log backups, Ive probably had to deal with a hundred disk capacity issues. Overall, I would estimate that such issues account for around 8. SQLServer2012.jpg' alt='Reduce Mdf File Size Sql Server 2008: Software' title='Reduce Mdf File Size Sql Server 2008: Software' />DBA team faces on a weekly basis. Occasionally, the cause of these space issues is just poor capacity planning. In other words, the growth in file size was entirely predictable, but someone failed to plan for it. Predictable growth patterns are something that should be analyzed right at the start, preferably before SQL Server is even installed. In my experience, though, these space issues are often caused by bugs, or failure to adhere to best practices. In this article, Ill delve into the most common causes of space management issues, covering model database configuration, inefficient bulk modifications, indexes and Temp. Im not a SQL expert, and Im reminded of the fact every time I need to do something beyond the basics. I have a test database that is not large in size, but the. MS SQL Server Quick Guide Learn MS SQL Server starting from Overview, Editions, Installation, Architecture, Managment Studio, Login Database, Create Database. Th Planet Be Blatant Racism. DB abuse, and how to fix them. I will finish the article by describing a query that you should store securely in your the SQL Server tacklebox, Size. Query. I use this query on more or less a daily basis to monitor and track space utilization on my SQL Server instances. Used in conjunction with the DBA repository to query multiple SQL Servers, it has proved to be an invaluable reporting tool. I have given a name to the time in the morning at which a DBA typically staggers in to work, bleary eyed, having spent most of the previous night shrinking log files and scouring disks for every precious Gigabyte of data, in order to find enough space to clear an alert. That name is DBA M pronounced D BAM, and its usually around 9. AM. My main goal with this article is to help fellow DBAs avoid that DBA M feeling. Common causes of space issues.

Most DBAs today operating their SQL Server database in full recovery model, schedule their transaction log backups to recur on a. Growth, Recovery Model and so on that are inappropriate for their intended use. Inefficient Delete, Insert or Bulk Insert statements such processes, plus those that create temp tables, can very quickly fill the log file with unnecessary data. The situation is exacerbated by incorrect Model database configuration. Indexes and large row counts clustered indexes can take up a lot of space for tables that contain millions of rows of data. However, you simply need to plan for this because the consequences of not having these indexes can severely impact performance. Blatant misuse of Temp. DB Temporary tables often play an important role when developers are tasked with comparing millions of rows of data, to return a small subset of results. This practice can have unwanted consequences, such as inadvertently filling the Temp. DB database. It is our job, as DBAs, to make sure this does not happen, often by performing a code review and offering an alternate solution. Over the coming sections, I am going to delve into each of these issues, and discuss the techniques I have used to analyze and fix each one, where possible. I say where possible because sometimes data growth really does exceed all expectation and confound even the most rigorous capacity planning. The only course of action, in such cases, is to expand disks or add additional SAN space, things only peripherally known to many DBAs. I want to stress that this article is not going to shine a light on SQL Server internals. I will not be taking you on a journey to the heart of the database engine to explore the esoteric concepts of leaf level storage. Every DBA needs to understand where and how objects, such as tables and indexes, use up space on your servers, and be very familiar with core concepts such as pages, extents, fill factors, as well as internal and external fragmentation. However, I will leave those details to Books Online. Here, I intend to drive the All Terrain Vehicle of my experience right to the source of the space allocation issues that wreak havoc on the waking and sleeping life of the on call DBA. Being a model DBAThis article is about space utilization in SQL Server and there is no better place to begin than with the Model database. The first thing I will say about the Model database is that, if it were up to me, I would rename it. Out of the box, there is nothing model about it it is not a model citizen nor should it be considered a role model for other databases. Nevertheless, it is the template upon which all subsequent databases are based, including Temp. DB. In other words, new databases created on the server, unless otherwise specified, will inherit the configuration settings of the model database. The full list of options for the Model database, including their default settings, can be found at http technet. The defaults for most of the options are fine for most databases. Most significantly, however, the model database settings determine the following Autogrowth properties for the data and log files. Recovery model for the database. The default settings for each of these are definitely not appropriate for all databases, and its easy for new DBAs, or even us old haggard DBAs, to forget to check these settings especially where were working with a server configured by a previous DBA. Beware of default autogrowth and recovery. By default, the data file modeldev for the Model database, for both SQL Server 2. MB in size initially, and is set to autogrow in 1 MB 1. K increments, unrestricted, until the disk is full. The log file is set at an initial size of 2. MB and is set to grow in 1. These settings are shown in Figure 1. Note Microsoft SQL Server 2. Books Online states The sizes of these files can vary slightly for different editions of SQL Server. I am using Standard Edition for the examples in this article. In SQL Server storage terms, 1.

For applications that are going to potentially load millions of records, growing the data file of a database every 1. SQL Server is IO requests. Figure 1 Initial sizes and growth characteristics for the model database data and log files. Rather than accept these defaults, it is a much better practice to size the data file appropriately at the outset, at say 2. G. The same advice applies for the log file. Generally, growth based on a percentage is fine until the file reaches a threshold where the next growth will consume the entire disk. Lets say you had a 4. G log file on a 5. G drive. It would only take two 1. Model database. Coupled with the previously described file growth characteristics, our databases will also inherit from the default model database a recovery model of Full. Transactions in the log file for a Full recovery database are only ever removed from the log upon a transaction log backup.
