Sql Server 2014 Error Log Location
Aug 19, 2011 by Paul 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 https://technet.microsoft.com/en-us/library/ms187885(v=sql.105).aspx 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: 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 http://sqlmag.com/blog/how-prevent-enormous-sql-server-error-log-files 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’ box and set your desired number of files – I usually choose 99. See the screenshot below. This doesn’t solve the size problem, but does mean that more error logs will be kept around. To solve the size problem, create a SQL Server Agent job that executes at some point every day and runs the command EXEC sp_cycle_errorlog; GO This causes a new error log file to be created and will prevent the error log becoming overly large on systems that do not reboot for a long time.

Tips: 1 | 2 | 3 | More > SQL Server Configurations Problem How do I find out where the SQL Server Error Log file is located for a specific SQL Server instance? In https://www.mssqltips.com/sqlservertip/2506/identify-location-of-the-sql-server-error-log-file/ this tip we look at different ways a DBA can identify the location of the SQL Server Error Log file used by an instance of SQL Server. Solution In this tip we will take a look http://blog.sqlauthority.com/2015/03/24/sql-server-where-is-errorlog-various-ways-to-find-its-location/ at three different ways you identify which SQL Server Error Log file is used by an instance of SQL Server. 1. Reading the SQL Server Error Logs2. Using SQL Server Configuration Manager3. Using Windows Application Event sql server Viewer Let's take a look at each of the above options in detail. Identify SQL Server Error Log File used by SQL Server Database Engine by Reading SQL Server Error Logs The SQL Server Error Log is a great place to find information about what is happening on your database server. You can execute the below TSQL command which uses the XP_READERRORLOG extended stored procedure to read the SQL Server Error Log to sql server transaction find the location of SQL Server Error Log file used by the instance of SQL Server. USE master GO xp_readerrorlog 0, 1, N'Logging SQL Server messages in file', NULL, NULL, N'asc' GO XP_READERRRORLOG The parameters you can use with XP_READERRRORLOG are mentioned below for your reference: 1. Value of error log file you want to read: 0 = current, 1 = Archive #1, 2 = Archive #2, etc... 2. Log file type: 1 or NULL = error log, 2 = SQL Agent log 3. Search string 1: String one you want to search for 4. Search string 2: String two you want to search for to further refine the results 5. Search from start time 6. Search to end time 7. Sort order for results: N'asc' = ascending, N'desc' = descending By default, there are six archived SQL Server Error Logs along with the ERRORLOG which is currently used. However, it is a Best Practice to increase the number of SQL Server Error Logs from the default value of six. Hence I recommend you read this tip Increase the Number of SQL Server Error Logs. Identify SQL Server Error Log File used by SQL Server Database Engine Using SQL Server Configuration Manager 1. Click Start -> Programs -> Microsoft SQL Server 2008 -> Configuration Tools ->
SERVER - Where is ERRORLOG? Various Ways to Find ERRORLOG Location March 24, 2015Pinal DaveSQL Tips and Tricks9 commentsWhenever someone reports some weird error on my blog comments or sends email to know about it, I always ask to share SQL Server ERRORLOG file. There have been many occasions where I need to guide them to find location of ERRORLOG file generated by SQL Server. Most DBA’s are intelligent and know some of these, but this is my try to share my learning about ERRORLOG location.I decided to write this blog so that I can reuse it rather than sending steps every time. At this point I must point out that even if the name says ERRORLOG, it contains not only the errors but information message also. Here are various ways to find the SQL Server ErrorLog location.A) If SQL Server is running and we are able to connect to SQL Server then we can do various things. So we can connect to SQL Server and run xp_readerrorlog. USE MASTER GO EXEC xp_readerrorlog 0, 1, N'Logging SQL Server messages in file' GO If you can’t remember above command just run xp_readerrorlog and find the line which says “Logging SQL Server messages”. B) If we are not able to connect to SQL Server then we should SQL Server Configuration Manager use. We need to find startup parameter starting with -e. Below is the place in SQL Server Configuration Manager (SQL 2012 onwards) where we can see them.C) If you don’t want to use both ways, then here is the little unknown secret. The ERRORLOG is one of startup parameters and its values are stored in registry key and here is the key in my server. SQLArg1 shows parameter starting with -e parameters which point to Errorlog file.Here is the key which I highlighted in the image: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Microsoft SQL Server\MSSQL12.SQL2014\MSSQLServer\Parameters\Note that “MSSQL12.SQL2014” would vary based on SQL Server Version and instance name which is installed.
