You are a database developer for a company. The company has a server that has multiple physical disks.
The disks are not part of a RAID array. The server hosts three Microsoft SQL Server instances. There are many SQL jobs that run during off-peak hours.
You observe that many deadlocks appear to be happening during specific times of the day.
You need to monitor the SQL environment and capture the information about the processes that are causing the deadlocks.
What should you do?
Correct Answer: F
Explanation/Reference:
Explanation:
To view deadlock information, the Database Engine provides monitoring tools in the form of two trace flags, and the deadlock graph event in SQL Server Profiler.
Trace Flag 1204 and Trace Flag 1222
When deadlocks occur, trace flag 1204 and trace flag 1222 return information that is captured in the SQL Server error log. Trace flag 1204 reports deadlock information formatted by each nodeinvolved in the deadlock. Trace flag 1222 formats deadlock information, first by processes and then by resources. It is possible to enable bothtrace flags to obtain two representations of the same deadlock event.
