alt=\"\" width=\"80\" height=\"80\" \/><\/p>\n<p><strong>Notes &#038; Recommendations<\/strong><\/p>\n<p>1) The event-time in SQL Server 2008 may strongly deviate (hours and days!) due to a mistake in the XML-code of the system_health session. Please also see the following Connect Item:<\/p>\n<p><a href=\"http:\/\/connect.microsoft.com\/SQLServer\/feedback\/details\/649362\/extended-event-session-system-health-diferent-timestamp-datetime-and-datetime-on-server-getdate\" target=\"_blank\" rel=\"noopener\">http:\/\/connect.microsoft.com\/SQLServer\/feedback\/details\/649362\/extended-event-session-system-health-diferent-timestamp-datetime-and-datetime-on-server-getdate<\/a><\/p>\n<p>2) In order to make sure that larger deadlock graphs are also captured, I recommend increasing the maximal memory of the system_health session as one sees fit.<\/p>\n<p>3) The size of the <em>Data<\/em>-database (<em>SQL_Analysis_Data<\/em>) may greatly expand with time. Use the clean-up procedure (<em>Locking.del_DeadLock<\/em>) inside the <em>Code<\/em>-database to remove old deadlock entries.<\/p>\n<\/div><\/section>\r\n\r\n<section  class='av_textblock_section av-av_textblock-2de302bf1aa3cf4c9157dbe6f50ac7eb '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-2779 size-thumbnail\" src=\"http:\/\/andreas-wolter.com\/wp-content\/uploads\/2017\/09\/Deadlock-Collector_Icon-80x80.png\" alt=\"\" width=\"80\" height=\"80\" \/><\/p>\n<p><strong>Call to Action: Quick Poll<\/strong><\/p>\n<p>I absolutely invite you to use my code free of charge and comment on any problems you may have or improvements you would like to see.<\/p>\n<p>All I would love for you to do is send me a high level statistics of what kind of deadlocks you see on your systems.<\/p>\n<p>Simply run the following query after you have collected new deadlocks, and send me the result, purely consisting of the Number of affected processes and number of deadlocks.<\/p>\n<\/div><\/section>\r\n\r\n<section  class='av_textblock_section av-av_textblock-2de302bf1aa3cf4c9157dbe6f50ac7eb '   itemscope=\"itemscope\" itemtype=\"https:\/\/schema.org\/BlogPosting\" itemprop=\"blogPost\" ><div class='avia_textblock'  itemprop=\"text\" ><p><img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-2815\" src=\"http:\/\/andreas-wolter.com\/wp-content\/uploads\/2017\/09\/Code_free.png\" alt=\"\" width=\"543\" height=\"265\" srcset=\"https:\/\/andreas-wolter.com\/wp-content\/uploads\/2017\/09\/Code_free.png 543w, https:\/\/andreas-wolter.com\/wp-content\/uploads\/2017\/09\/Code_free-300x146.png 300w, https:\/\/andreas-wolter.com\/wp-content\/uploads\/2017\/09\/Code_free-450x220.png 450w\" sizes=\"auto, (max-width: 543px) 100vw, 543px\" \/><\/p>\n<p>You can use comments or also send me an email if you have access to it.
