第22题：
You are the administrator of a SQL Server computer. Users report that the database times out when they attempt to modify data. You use the Current Activity window to examine locks held in the database as shown in the following screenshot.
You need to discover why users cannot modify data in the database, but you do not want to disrupt normal database activities. What should you do?
A．Use the spid 52 icon in the Current Activity window to discover which SQL statement is being executed
B．Use the sp_who stored procedure to discover who is logged in as spid 52
C．Use SQL Profiler to capture the activity of the user who is logged in as spid 52
D．Use System Monitor to log the locks that are granted in the database
正确答案：A
解析：Explanation: The current activity window in SQL Server Enterprise Manager can be used to perform. ad hoc monitoring of an instance of SQL Server. This allows for the quick analysis of the volume and general types of activity on the system and can indicate current blocked and blocking transactions, currently connected users on an instance of SQL Server and the last statement executed and locks that are in effect on the database.
In the screen shot of current activity window the icon, labeled spid 51, indicates that a database lock is in place; the second icon, labeled spid 52, can be used to identify the process that is blocking one or more connections; and the third icon, labeled spid 53, can be used to identify the process that is being blocked by another connection
Incorrect Answers:
B: The system stored procedure sp_lock can be used to return a result set that contains information about resources that are locked and the sp_who stored procedure provides information about current SQL Server 2000 users and processes. The information returned by the sp_who procedure can be filtered to return only current non-idle processes. This makes it possible to identify which resources are being locked and which processes are responsible for creating those locks. These stored procedures require more resources and more administrative effort than the Current Activity window. It is therefore not the best answer.
C: The SQL profiler is not the best tool to immediately solve the locking problem. It could be used at a later moment if a long-term solution to the problem is required. SQL profiler would require more system resources and might impact normal database activities.
Note: SQL Profiler is a graphical tool that allows system administrators to monitor events in an instance of SQL Server. Data pertaining to an event can be captured and saved to a file or SQL Server table to be analyzed at a later date. It can be is used to step through problem queries to find the cause of the problem; to find and diagnose slow-running queries; to capture the series of SQL statements that led to a problem; and to monitor the performance of SQL Server to tune workloads.
D: SQL Server provides objects and counters that can be used by System Monitor in a Windows 2000 or by Performance Monitor in Windows NT 4.0 to monitor the system performance of computers running an instance of SQL Server. However, these counters are used for statistics and alerts and they cannot, in a direct way, be used to track down the cause of the locking problem.
