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 identify which queries are taking longer than 1 second to run over an extended
period of time.
What should you do?
A.
use SQL Profiler to trace all queries that are processing on the server. Filter queries that
have a Duration value of more than 1,000.
B.
Use sp_configure to set a value for blocked process threshold. Create an extended event
session.
C.
Use the Job Activity monitor to review all processes that are actively running. Review the
Job History to find out the duration of each step.
D.
Run the sp_who command from a query window.
E.
Run the DBCC TRACEON 1222 command from a query window and review the SQL
Server event log.
Explanation:
Verified the SQL Profiler and DBCC answers as correct. However, while Profiler will show
this information, the best practice with Profiler is to use it short-term. The question
specifically states “over an extended period of time”. That means Profiler wouldn’t be the
best tool for this scenario. Therefore, DBCC would be the best answer.http://www.mssqltips.com/sqlservertip/2130/finding-sql-server-deadlocks-using-trace-flag-
