You administer a Microsoft SQL Server 2012 server. One of the databases on the server supports a highly active OLTP application. Users report abnormally long wait times when they submit data into the application. You need to gather blocking data over an extended period of time. You also need to ensure minimum impact to server performance. What should you do?
A. Run the DBCC TRACEON 1222 command from a query window and review the SQL Server event log.
B. Use sp_configure to set a value for blocked process threshold. Create an extended event session.
Which one of the 2 is correct and why please?
