How To Reduce Log File Size In Sql Server 2008
S. Randal in SQL Server Questions Answered RSS EMAIL Tweet Comments 0 Question: Some of the SQL Server instances I manage routinely have extremely large (multiple gigabytes) error logs because they are rebooted so infrequently. Trying to open an error log that large is really problematic. Is there a way that the error logs can be made smaller? Answer: sp_cycle_errorlog best practice I completely sympathize with you. Very often when dealing with client systems we encounter similar problems. Thankfully there is an easy solution. (See also, "Choosing Default Sizes for Your Data and Log Files" and "Why is a Rolled-Back Transaction Causing My Differential Backup to be Large?"). The number of error logs is set to 6 by default, and a new one is created each time the server restarts. Old ones are renamed when a new one is created and the oldest is deleted. As you’ve noticed, this can lead to extremely large error log files that are very cumbersome to work with. There is a registry setting ‘NumErrorLogs’ that controls the number of error log files to keep in the LOG directory. This can easily be changed through Management Studio. In Object Explorer for the instance, navigate to Management then SQL Server Logs. Right-click and select Configure as shown below. This brings up the Configure SQL Server Error Logs dialog. Check the ‘Limit the number of error log files before they are recycled

This command returns information about the amount of log space currently used, and indicates when the transaction log needs truncation. For more information, see DBCC SQLPERF (Transact-SQL). For information about the current size of a log file, its maximum size, and the autogrow option for the file, you can also use the size, max_size, and growth columns for that log file in sys.database_files. For more information, see sys.database_files (Transact-SQL).Important! Avoid overloading the log disk!Shrink log file sizeTo reduce the physical size of a physical log file, you must shrink the log file. This is useful when you know that a transaction log file contains unused space you will not need.You can shrink a log file can occur only while the database is online and at least one virtual log file is free. In some cases, shrinking the log may not be possible until after the next log truncation. Note Fact

The sql server error log is what allows you to restore your database if there is a failure.The way you truncate a log file depends on what version of sql server you are running. If you are going to truncate the log file I would suggest that right after you truncate it you create a backup of your database so you are covered.You should regularly backup your database and at that time you could truncate the log file.All of that being said, to truncate a log file in sql server 2008 you can switch between recovery modes:declare @dbname varchar(100)exec('alter database '+@DBNAME+' Set Recovery Simple') exec('alter database '+@dbname+' Set Recovery Full ')Your database name would have to be in the @dbname variable.

Facebook Twitter LinkedIn YouTube GitHub Forgotten Maintenance - Cycling the SQL Server Error Log September 30, 2015Jeremiah Peschka20 comments Most of us get caught up in fragmentation, finding the slowest queries, and looking at new features. We forget the little things that make managing a SQL Server easier - like cylcing the SQL Server error logs. What's the Error Log? The SQL Server error log is a file that is full of messages generated by SQL Server. By default this tells you when log backups occurred, other informational events, and even contains pieces and parts of stack dumps. In short, it's a treasure trove of information. When SQL Server is in trouble, it's nice to have this available as a source of information during troubleshooting. Unfortunately, if the SQL Server error log gets huge, it can take a long time to read the error log - it's just a file, after all, and the GUI has to read that file into memory. Keep the SQL Server Error Log Under Control It's possible to cycle the SQL Server error log. Cycling the error log starts a new file, and there are only two times when this happens. When SQL Server is restarted. When you execute sp_cycle_errorlog Change everything! When SQL Server cycles the error log, the current log file is closed and a new one is opened. By default, these files are in your SQL Server executables directory in the MSSQL\LOG folder. Admittedly, you don't really need to know where these are unless you want to see how much room they take up. SQL Server keeps up to 6 error log files around by default. You can easily change this. Open up your copy of SSMS and: Expand the "Management" folder. Right click on "SQL Server Logs" Select "Configure" Check the box "Limit the number of error log files before they are recycled" Pick some value to put in the "Maximum number of error log failes" box Click "OK" It's just that easy! Admittedly, you have to do this on every SQL Server that you have, so you might just want to click the "Script" button so you can push the script to multiple SQL Servers. Automatically Rotating the SQL Server Error Log You can set up SQL Server to automatically rotate your error logs. This is the easiest part of this blog post, apart from closing the window. To cycle error logs on a regular basis, restart your SQL Server nightly. Only joking. You can set up a SQL Agent job with a T-SQL step. All it has to do is EXEC sp_cycle_errorlog. Schedule
